Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

My sony Bravia kdl-46v5500 screen has colored lines on the left side then half the screen flicks black then the same left half side of the screen stays black then will go back to normal and then go...

These sets use for the most part two boards--each drives the screen on one side---also possible as suggested here the problem is inside the panel or where it connects to these boards--if inside the panel (the entire front screen unit) it is fatal as it cannot be got at and the display costs more than the set did new.

THIS set uses 2 boards inside--one drives the left and the other the right side of the screen.

You have to id which is which (GOOGLE?) AND replace it-every brand has different names for these but it sounds like your problem

Some research (you or me) should give a board breakdown for this model---not looking for main or power board but another like sustain etc. and there will be 2 listed (for right and the left sides)

Half screen is blank 42lg20 or 42lg50 when

This is likely to be the T-con board. If the entire screen glows but you have no picture on the second half of the screen then it is the main board, not the backlight inverter. If the screen is half picture and half gray it is the T-con board.

Replacement of one of the above will fix the issue.

Please rate if this helped :)

The TV has a Black cloud on the right half of the

My parents have the same issue with their Sony KDL-46V4100 TV and were told by the tech that the LCD screen was physically broken and would have to be replaced. The replacement of the screen would cost more than a brand new TV and the TV is not longer under warranty. After the TV is on for awhile the Black cloud goes away but it always comes back when they turn the TV off/on. It stays for 20 - 30 minutes sometimes. The Tech took both top corners of the TV and pushed one back and pulled one forward to show them he could recreate the problem after the black blob cleared up. By twisting the corners he made the blob reapper which he claimed was becuase of the damaged screen. I have no idea how the screen was damaged? I helped them take it out fo the box and set it up. We never dropped it bumped it once? It's never falled off the stand so go figure? It would be nice to find more people with this issue and get a recall going. Something that expensive should last longer than to two years.

I have a 32in element flat screen had for couple of months now tonight there is a black box in the middle of my screen what should i do

I would like to know the same. We purchased ours on 10/25 and on 12/29 a black half moon shape showed up in the lower left hand side of the screen. Now the rightmost side of the screen is almost covered in black circles. There are also varying widths of lines going up and down on the right half of the screen.

We have tried contacting cusomer service and keep getting voicemail.

42" LCD tv shows picture on only half of the screen,other half dark!

The T-Con board (otherwise known as LVDS) connects to two seperste parts of the LCD panel. If you do have half a picture (left or right) replacing the T-Con board should resolve this issue. Open your TV, find the part number and search on eBay or at sites like where you can search by TV model number.
