Question about Sony Televison & Video

1 Answer

I have a Sony 52 inch bravia LCD TV KDL52W4100 which has developed a problem recently. it started with a couple of horizontal lines about six inches long and about 1/3 of the way down the screen, then the next day or so more lines are appearing. these lines are only visible in the lighter areas of the screen (never when black is present in a picture). every week or so more lines are appearing in different areas of the screen always horizontal and always in a straight line. Please help!!! Thanks, John....

You have a bad t-con board . Replacing it should resolve the issue. It is rather inexpensive too. If you want to do it yourself then let me know and I will help you find a replacement board.

    It is pretty easy. There are a pair of ribbon cables that go into the display(in some cases the board is attached to the display itself. That will be tougher) . Just unplug the connectors, unscrew it from the chassis, screw the new on in and plug the connectors. However there are a couple of precautions you should take.

    1)Unplug the set before you start working on it. Also do not touch any capacitors that hold potentially lethal voltages for several days even after the set is unplugged.
    2) Make sure you discharge the ESD by touching some grounded metal for a few seconds before you start touching the PCB. ESD is the worst enemy of the ICs.

    I can find you the part if you can get me the part number off the board!

    John, did your lines start out green when you turned on the TV and when the picture came up they are white???? because I'm having that problem and my TV is only 2 years old.... wondering if it's the same thing???

    Thanks,

    Stacey

If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Sony 52 inch XBR with bands of ghosted images


Its a TAB bond Problem with the LCD. You can take apart the TV and install a rubber Bumper to put pressure on the TAB. TAB bonds always get worse... I dont know how long it will solve the issue... but u can get a little more life out of it.
Rember when working with the TV the voltages can kill!!
Heres a link to see someone fixing.
I have the same TV...same problem...common problem...unless u ask Sony.

I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...


The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

12 little horizontal lines in Sony Bravia KDL-52W4100


It's the panel. Mine took a sharp force trauma when it fell only 1 foot onto something very pointy (a cellular external antenna) and it looks like it got shot by a bb gun. And it has lines kind like what you are describing.

You can't fix an LCD tv with this kind of problem. You just can't. The LCD panel cost more than a new TV. I know I asked the local Sony Shop to just order me the LCD panel. It was over $900 on a $600 retail TV. I was going to replace it myself ... I fix laptops ... but not at that price. So far I'm just using it as it is, until I want to, and have the $$$ to buy another one.

Good luck on yours.

(a laptop lcd panel repair costed over $300 by the way on a $600 laptop with a few years age on it. I did it mainly as a learning experience. But never again.)
