Revive Your Broken TV with THIS SECRET Method - මෙහෙම ටීවී හදල බලමු

#ledtv_repair #repair #backlight #nopicture #nosound #easy #tvrepair LED TV Backlight Repairs. When TV backlights have failed, we usually find between 1 and 3 LEDs have failed however there are usually between 40 and 120 individual LEDs in your TV so it makes sense that the backlights all being the same age, are all ready for failing. You could argue that some would last another 3 or 4 years however most engineers that repair the individual LEDs will end up repairing your TV again perhaps 4 or 5 times in the next 2 years, which becomes far more costly than doing the job properly first time. Repair Method 1 As a TV backlight repair specialist, we are one of the few in the UK that import backlight strips directly from China and Korea. We always replace all the strips which contain all the LEDs and effectively put the set back to the same condition as it was when new, hence we can offer a full 12 months part & Labour warranty on the new set fitted Unfortunately, some backlight strips are not available to buy new, so some TVs we cannot offer a repair. Repair method 2 This involves removing the diffuser lens from the backlight strip and replacing the individual LEDs that have failed. These LEDs cost pennies so you are essentially just paying the labour charges for the engineer to do the job. if done correctly and replacing the faulty LEDs with correct replacements this method is not dangerous or a fire risk. however, we do not understand why engineers still prefer this method. perhaps it’s the fact that they can charge you every time another LED fails or possibly that most engineers are over 60s and close to retirement and do not want to invest thousands of pounds and the risks and time involved in importing from China and Korea. This repair would usually have little or no warranty Repair methods 3 This is very common but is one to completely avoid, this involves removing the diffuser from the faulty LED and removing the LED itself, then getting another second-hand strip and cutting a backlight from that strip and gluing it on top where the faulty LED has been removed. then the backlight strip is scraped to reveal the copper connections and wires are soldered to connect the new backlight to the existing backlight strip. This looks an awful mess and is potentially dangerous and we have seen these burnt many times. Again, it will last for a few weeks to a few months at best till that one or another fails. this repair will have little or no guarantee * facebook group :- https://web.facebook.com/share/g/TKMEjv8rqj7bbr2b * blog :- https://srilankaamatech.blogspot.com/ * instagram :- https://www.instagram.com/sisirachaminda36 * twiter :- https://twitter.com/AmaTech99 Join this channel to get access to perks: https://www.youtube.com/channel/UCwvy7eno-geCMY6XPAI105Q/join Thank you !! for watching , like , comment and share my videos.

👀 Are you experiencing issues with your TV’s display? It could be due to a faulty T-Con board. This small but essential component is responsible for controlling the timing and signal processing of your TV’s display. If it’s not functioning correctly, it can cause a range of symptoms that affect your viewing experience.

📺 One of the most common signs of a faulty T-Con board is horizontal or vertical lines on the screen. These lines can be thick or thin, and they may appear in different colors. Another symptom is a blurry or distorted image, which can make it difficult to watch your favorite shows or movies. In some cases, the screen may even go completely black.

💻 Other T-Con board symptoms include ghosting, where images appear to trail behind moving objects on the screen, and flickering, where the display rapidly switches between on and off. If you’re experiencing any of these issues, it’s important to get your TV checked by a professional. Ignoring the symptoms could lead to further damage and a more expensive repair bill.

led tv panel blue color problem - led tv එක ඉක්මනින් ගෙඩදාමු

#sony #led_tv #coloring #problems #how_to Follows these steps to fix a TV that looks blue. These steps should resolve the problem caused by incorrect settings on your television, incorrect settings on a device, or a faulty connection. Turn the TV off and back on again. Doing this rarely helps but only takes a second and has a slight chance of resolving the problem. Press the Menu button on your television's remote. A list of settings should appear on the television. Look for a section labeled Image Mode, Picture Mode, or Display Mode. This section will include preset modes with labels such as Cinematic or Bright. Flip through these modes to see if the resulting image is more to your liking. Press the Menu button on your television's remote. Look for a section labeled Color Temperature. It will list presets with labels such as Warm and Cool. Change the color temperature setting to Warm. Some TVs will instead list color temperature in degrees Kelvin, such as 6500K or 5700K. Adjust the TV to a setting below 5000K. Try changing the color temperature on the device sending the video to your television. The steps for this will vary depending on the device, but many offer image, video, or picture settings that can impact image quality. Consult the device's manual for more information on the settings it provides. Check the connection of the device sending video to the television. Make sure the video cable, usually an HDMI cable, is firmly connected to the TV. How to Troubleshoot HDMI Connection Problems Check the HDMI cable connecting the device you're using to your TV. Look for signs of wear, including cuts, tears, exposed wiring, or knots. Replace the cable if you notice any damage. Remove the HDMI cable from the television. Check the end of the HDMI cable's connector and the TV's HDMI port for signs of damage. Replace the cable if the connector appears damaged. If your TV's HDMI port seems to be damaged, try using a different port. Try connecting a different device to your TV through a different HDMI port. It will help you determine if the problem is with your TV or the device connected to it. facebook page :- https://web.facebook.com/groups/amatech99

led tv repair no sound no picture - පහසුවෙන් LED TV එකක් හදමු

#panel_repair #backlight #no_sound #no_picture #standby_ok How to replace Tv Led Backlight? Backlighting is at the heart of how TVs work. ............................................................................... TVs work by allowing a filter system on the back of the display to generate the image seen on the screen. However, if the "backlight" is damaged or stops working, the owner may be left with a very expensive paperweight. No need to buy a new TV, just a few steps to replace the backlight. Step 1 Remove all screws on the back of theTV. The number of screws will vary by model, however, the screws are usually located around the edge of the rear case. Gently lift the rear panel away from the monitor and remove any metal pieces underneath to expose the TV's internal components. Step 2 Locate and remove the backlight from the LCD. The backlight will be a slender tube in a clear plastic case. In a well-ventilated area, use a dremel tool to carefully cut into the end of the plastic housing closest to the end where the tube lead connector enters the plastic housing. Step 3 Use a hair dryer to heat the area where the tube wires go into the plastic casing. Once the glue holding the wires in place is hot enough, carefully pull out the wires and tubes. Use extreme care when handling backlight tubes, as the presence of mercury vapor can pose a health risk if the tubes are damaged. Make sure to perform this step in a well-ventilated area. Step 4 Unscrew the reflective strip and reinstall the new backlight just like the old backlight you removed in step 3. Reattach the reflective strips to the monitor and screw the LCD TV's housing back into place. Thank you !! for watching , like , comment and share my videos.

How to fix vertical colorful bar and lines LED TV - led tv ගෙදරදීම හදමු

#led_tv #Hisense_led_tv #vartical_line #panel_problams #colorful After a year or two or owning your Hisense TV, vertical lines can start to show on-screen. Many people choose to chuck their TV and get a brand new model, but it’s actually very simple to fix Hisense TV vertical lines. Hisense TV Vertical Lines on Screen To fix vertical lines on a Hisense TV, check all HDMI and signal cables are securely seated with no oxidation on their contacts, then power cycle your TV to reset it, unplugging it from the wall for 30 minutes and holding down the TV’s power button for 15 seconds, before plugging it back in. In the vast majority of cases, this will fix your Hisense TV, but in case you still see vertical lines, or if you need more info on how to apply the fixes above, then you can follow the detailed steps below to get your TV working again. This guide will give you all the necessary know-how to fix this yourself and get your TV back up and running again without needing an expensive replacement. 1. Power Cycle Your TV Running your Hisense TV through a power cycle will help to clear any potential issues that could be caused by its capacitors retaining charge or internal flash memory holding onto a glitch that is causing the vertical lines. This is quick and painless and won’t cause you to lose any of your saved settings. Unplug your Hisense TV and hold down the physical power button beneath the IR receiver on the TV for at least 15 seconds. Wait for at least 30 minutes for any residual power to drain. Plug your TV back in and try switching it on. You should see a red light if you have been successful. Although this seems a very basic step, don’t overlook it because in the vast majority of cases a simple soft reset fixes most issues. 2. Unplug Your HDMI Cables There’s a strong possibility that a poorly seated cable is creating signal noise which is displaying as vertical lines, and is also a common cause of horizontal lines on Hisense TVs. Faulty HDMI cable with a break in it Damaged HDMI port with broken pins Poor HDMI connection where the cable and connector are not fully making contact To check your HDMI and other cables: Switch off your TV. Remove any HDMI or other physical cables connected to the back of your TV. If you have any compressed air, use that to clean the contacts both of the cable and in the connector on the TV. If you don’t have compressed air, then blow gently on them. Firmly push the cables back into their slots on the TV. Switch your TV back on again. It that hasn’t fixed the problem, then try using a different HDMI input. Most TVs have 3 or 4 HDMI ports. Update Your Firmware Software and firmware issues have been known to cause problems with the display on Hisense TVs. As with any product, you should ensure that you have updated your TV’s firmware to the latest version, even if it is new. Most Hisense TVs support auto-updating of firmware, but you can’t assume that this is turned on for you. Check Over-the-Air (OTA) firmware updates are enabled for Smart Hisense TVs by pressing the Home button on your remote, then go to the “cog” for settings, then Support and System Update. Make sure the Auto Firmware Upgrade is enabled. If your TV doesn’t have OTA support: Press Home on your remote. Click the “cog” icon. Go to All. Then About. And System Update. Click Detect to check for updates. For older Hisense TVs, even this option for updating your firmware might not be available. In this case, you need to download the latest firmware and install onto a USB stick to install it manually on your TV. Call Hisense Support and they will be able to guide you through the process. Try Reseating the T-Con Cable The Timing Control (T-Con) board is a small PCB board that drives your TV’s panel, translating the signal into a picture on your screen.It’s hidden away under the back panel, behind the screen, and is a regular source of vertical lines in TV images because it connects to the LCD / OLED panel with ribbon connectors which can come loose. To access the T-Con board, you need to remove the back panel. If you’re not confident doing this, then now is the time to get an expert in. Otherwise: Unplug your TV, hold down the power button and wait for at least 30 minutes. There are large capacitors in the power board for the backlight and these can hold charge for an extended period of time. Place your TV face down on a large table or workbench. Make sure there is nothing that can scratch the screen on your work surface. Ground yourself. Open your TV by unscrewing the screws in the backpanel. It should come apart in two pieces: front and back. Put the back panel somewhere out of the way and take a look at the circuit boards that have been revealed. You will see a T-Con panel for translating the signal into a TV picture, a power board and a motherboard board. Thank you !! for watching , like , comment and share my videos.

how to Turn on led lcd tv power board

A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power, see AC adapter) to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy. A hypothetical ideal switched-mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time (also known as duty cycles). In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage.

Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller. This is because it operates at a high switching frequency which ranges from several hundred kHz to several MHz in contrast to the 50 or 60 Hz mains frequency. Despite the reduced transformer size, the power supply topology and the requirement for electromagnetic interference (EMI) suppression in commercial designs result in a usually much greater component count and corresponding circuit complexity.

Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight is required. They are, however, more complicated; switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.

Sony Led Tv Coloring Vertical Lines: Easy Fix

#led_tv #repair #pannel #Vertical_Line try these below methods and your issue with sony tv vertical lines on screen will be fixed successfully.These are the simple issues to troubleshoot and fix. First start removing and resetting video cable of both TV and video source. If it is not the problem, use different cables to know better. Still you are facing the issues, switch it to different source For example: if you are watching TV through coaxial cable, then switch it to HDMI input or VGA input. If your problem exists that continue to appear lines, the issue is likely an internal problem. Usually TV screen pixel is made of semi transparent colored crystal and light is shined through Crystal’s. If pixel of vertical row or line has died, then entire row will become solid black. Then pixel cannot be repaired entire screen will be replaced to repair the TV. So, of there is white or flickering line it involves in the internal connection from signal processor to the screen.Each pixel is connected Separately through a firmly wire to the Signal control circuit board and sometimes it may disconnect. A useful way to determine if it has happened is to spray canned air along the left and right edges of screen with vertical line appears. If line disappear after spraying cold air along edges of screen, it might be a boarding problem, that can be solved by cooling wires Which improves conductivity. If bonding failure It cannot be repaired permanently so screen should be replaced.When the line appear as thick or thin, black or white, it may be centre or border, it may interfere in viewing experience. Unfortunately, these may signify several technical problem that signal between unit processor or display screen.T- CON means timing control board, it is the one of the part of screen that relay message between the device processor, brain and display itself. When the T-CON board fails, the timing between different parts interrupted and lead to both horizontal and vertical lines are well as pixelation. The only way to fix is to have T- CON board is replacement.While some #vertical_lines are the result of damage to your screen. Anything that interface with an internet or satellite signal such as improper aligned satellite dish or frayed coaxial cable, may has potential to cause picture distortion, including but not limited to lines on screen and fixed problem. Even the source itself transmit image with lines on it. For example: local TV news station that suffers signal interface during live shot may broadcast image with lines pixelation or ghosting. #pannel_repair #vertical_line #sony_led_tv #led_tv Thank you !! for watching , like , comment and share my videos.
