Problem with coloured vertical lines covering a 5" section of a 32" logik lcd tv

Hi there,

I'm trying to repair my Logik LOG32LW782 lcd tv. The fault is a set of numerous vertical coloured lines running from the top of the screen to the bottom with an overall width of about 5 inches. The affected section is on the very right side of the screen, and the rest is completely fine and shows a good picture from all inputs.

Can anyone help in suggesting what the cause might be? I've had a bit of experience before in changing inverter boards, but not seen this before. I'm trying to diagnose the cause before I resort to taking it in for repair.

So if anyone can suggest what might be causing it, and/or what part might need replacing or looking at, I'd be very grateful!!

Thanks very much!

Dan Henderson

    Hi there,



    Thanks for the answer. If the driver is having a problem, is there any way of fixing that rathger than replacing the screen? Surely the actual screen is in working order as it's showing light? I've taken tv's apart before, so do you know what part I'd be looking to replace, or what I'd be looking for?



    Also, is there any way of finding out how to restore the tv to it's factory defaults? I've not got a manual and can't find anything on the internet...do you know if there's a sequence of buttons that can acheive it at all?



    Thanks very much,

I have a 22" Logik


The problem is related to the section which processes the video/picture information in the TV. Most likely an IC or its surrounding components.
Try consulting TV repair technician.

All the best

If you're relying on cheap cables - like the ones that are usually tossed in with electronics - you could be running into a signal issue because they aren't shielded and they lose alot of signal due to leakage.

You don't have to overpay for Monster cables, mind you, but cables that are shielded - in gold is even better - should help improve your signal.
