    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?

    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.
