    Lg 37lh3000 white screen issue

    Hello to all.

    I was hoping I could get some advice. I have just realised how much I depend on my TV now it's stopped working.

    It's an LG 37lh3000 and over 5 years old. When I changed the input selection to PC, the screen started to flicker for a few seconds, then turned white. I can still operate the menu, although can only just make out the text. Sound is still OK.
    It's been playing up for the last year, where it can take a while to pick up a connection, and flickered from time to time. I put this down to bad connections on the HDMI and never happened enough to annoy me.

    Anyway. Having looked around, I keep hearing the Tcon board is most likely the problem, although I'm struggling to find a replacement part. I have tried to reconnect the video cable going to the Tcon, and also the connectors going to the screen. However, I cannot access the connectors to the actual screen as it's enclosed within a mental frame.

    I have a nasty feeling I will need to buy a new TV, but obviously want to try everything else first including finding a new TCON.

    Does anyone have any ideas please?

    many thanks

    I've located the tcon board here for 30 pounds, does that sound OK?

    http://www.lcd-plasma-parts.co.uk/t3...n?search=26793

    The number I have, is UT-5537T04C36-998-2075669-00492-03

    There is also another code: T37OHWO2 VG

    Not sure what to do.

      I have ordered that part. I'll be sure to update in a couple days when it arrives. Fingers crossed. Far cheaper than a new TV

        Just reporting back to let anyone know that the replacement Tcon board fixed the issue.
        There is a certain chip that is notorious for failing.

            Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
            by Daren87
            Hello everyone,

            I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

            TCL 50S535 bad tcon or panel issue?
            by x_orange90_x
            Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

            Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
            by wizard13
            Hello everyone,

            I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

            I have checked the forum and the available documentation but could not find a solution specific to my issue.

            Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
            by Ryan.man
            Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

            My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

            This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

            HELP - Contrast/brightness issue with subtitles on screen
            by cloudy
            Hi everybody
            Since day one I'm having an unpleasant contrast/brightness issue on my Asus laptop.
            Basically while watching movies, if subtitles appear on screen, the contrast or the brightness of the entire screen increases a lot (not sure if it'is brightness or contrast), disturbing the viewing of the movie.

            Last year I replaced my screen because got damaged and this contrast/brigthness issue persists. It happens only on the laptop screen, in fact If i plug an external HDMI screen the issue does not occour on it.

            It occours both on ubuntu and windows...
