    Inside a 32" LCD TV panel

    I just recently was able to repair a 32” LCD television.
    The broken one was Samsung and it had a broken CCFL,I had a Sony of the same size with a broken screen so I was able to salvage a CCFL from it to repair the Samsung.
    Here's a picture of the inside of the panel
    Looks like the returns of all the CCFLs are hooked to a chassis ground
    The CCFL was actually easier to replace than the ones I do on LCD monitors

    Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

    On the inside of this monitor there are some white plastic clips that secure the CCFLs to the frame of the LCD.The CCFLs snap into these to position them in the correct place. I was very careful when I removed the CCFL tubes but the clips broke. Is there a place where you can purchase these if they do brake?

      rtv silicon will work fine and take any heat (auto parts store). The plastic clips are very easy to break.

        Nevir 39" LCD acting up. Broken panel?
        by edugimeno
        Hi! I got this TV that was supposed to "not work well".

        I turned it on and the BL got lit but nothing was showing on screen

        Opened it and found that the only PS voltages present (12v and backlight) were 100% perfect

        Plugged it back in and the screen kind of started up showing a NEVIR logo but it was split into several chunks with also missing lines in between. Nothing else

        Next time the screen showed an amorphous large color cloud in the screen swinging from side to side (maybe a screensaver picture) with all broken lines everywhere....

        Sony KD-65A1 Repair – 4 Red Blinks Error
        by AK_777
        Hi everyone!
        I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

        Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

        Acer Nitro XV273 and Predator XB273, look inside and disassembly guide.
        by Flaku_34
        Introduction:
        Hello everyone, this topic is more of a knowledge sharing and look inside type of post, but for someone working on this model of display it might be useful. Recently I bought Acer Nitro XV273 XB MIIPRZX with busted electronic, but screen was intact, price was incredibly low, so I took a gamble and bought the unit and try to fix it. As I dug inside, I found out that my motherboard was not responding, although all voltages seemed fine. I wasn't able to find any reliable information about this monitor on the web (only some pictures of motherboards from Ebay). By some research...

        HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
        by ttmi100x
        Greetings everyone,


        I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


        The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
        Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

        Upon closer inspection...

        LG L192WS-BN backlight turns off after 1 second
        by www
        I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.

        I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue....
