LOG26LW782 Logik Display Fault

[D.R.]

Hi,

I have recently saved a Logik LCD TV from a trip the skip and I'm looking for some advice on how to rectify its fault.

When you switch it on it displays a grey screen for up to 20mins, depending on when it was last switched off, during which you get sound and can switch channels and after which it works perfectly. The grey screen fault can be as little as 3mins or no grey screen if its just been switched of then back on.

I was thinking it was a capacitor charge / discharge issue due to the variable grey screen time and rather too eagerly re-caped the PSU to no avail but after reading several posts I am leaning towards a faulty T-Con board.

I cant find a service manual for the TV so if anyone can suggest places to look it would be appreciated. I'm an Electrical Engineer (but not a TV Eng) so feel free to suggest a place or two to poke around with a multimeter.

I've found a place selling the correct T-Con board for £35 but I'd rather fix it if at all possible. Any help would be much appreciated.
