Sony Bravia KVL-V40A10 - pixelated lines top and bottom of screen

that isa capacitor at vertical area mostiy 1000 uf to 22000 /35volts

this is caused by the panel's edge contacts coming loose(delaminating). would have to replace panel(approx. 1500.00 usd.)

top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

sadly you have a bad panel. Sony panels carry a two year warranty.
your best hope is to call Sony and ask for a warranty extension to cover the cost of the part.

This sounds like what I managed to do to my screen, even though I knew better. Is there any chance you layed the screen face down at some time?

Even though you can still watch it OK, you probably have hairline fractures in the screen face (NOT the screen itself- be thankful for that- the cracks are in the screen coating). LCD screens are a very thin glass laminate with a thin protective glass-like coating. When they are laid flat (like I did to connect cables) if the screen bears any weight, microcracks develop on the front of the screen.

I am sorry to say that the effect is permanent.

Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.
Thanks.

It sounds lcd screen problem and lcd panel (screen) will be replaced. Please check with local tv repair shop or nearest Sony service center for lcd screen replacement.

I don't know what does your mean by "line up and down my screen", if the line goes up from the bottom to reach the top of screen then goes back down to the bottom cycles, that symptom I have never seen. But if the line goes off and on, very high probability is the panel defective (see the picture, the ICs inside the panel loose, shall cause the Vertical or horizontal dead pixel lines). It is the most serious issue on the flat panel TV. Because the manufactory sells the panels, price even excess the TV.
If you need more accurate diagnose, you can post a picture.

Sounds like someone hit and broke the screen. Not repairable and not a warranty claim...

Hi,

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty

The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.

All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.

The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

Thanks
