Hi all,

Just after a little advice.

I have a 37" LG LCD tv.

For the past few days everytime I watch tv there is a vertical line about one pixel wide on the left hand side.

It runs from the bottom until about half way up the screen.

It is sometimes yellow and other times blue.

Can this be repaired or will i need to buy a new tv?

The tv also has a buzzing sound when first turned on, I don't know if that related.

Many thanks

It's most likely a fault in the LCD panel, and replacing that would probably cost more than a new TV.

Could it be that you have changed the Aspect ratio from 16:9 to what LG call Just Scan? In 16:9 the TV very slightly zooms into the image so you lose a small bit on all four edges. With Just Scan it "zooms" out and displays every pixel "as is".

I noticed on my LG TV that when you set Just Scan you can sometimes see odd imperfections round the edges from time to time. Depends to some extent on what you are watching.

Just Scan is on the Picture menu Aspect Ratio setting. Might be worth double checking. Though what I can't remember (and not in front of the telly to check) is if this option is available on every input or just the HDMI inputs.

It could be a faulty T-CON board which is the majority of the vertical lines problem !

most common fault is a capacitor, cheap and easy to fix. not if you let the repair men fix it..

Sorry, capacitor problems don't cause lines of duff pixels - that's the LCD panel (or - as Prilica suggested - the T-Con board, which is part of the panel anyway, but most likely the LCD panel itself).

Thank you all.

I might try and replace the T-CON board as suggested.

Is this easy to replace?

Otherwise i'll just send the tv to the tip.

It's fairly easy, but can be a little 'fiddly' - as they often have very thin ribbon connectors, and these often latch in devious ways, you might have to lever it up, push one end in, push both ends in, squeeze them together etc.

However, the T-Con board is a fairly low percentage option, assuming you can source one at a reasonable cost (it's actually part of the LCD panel, and often not available separately).
