Top 20 Sony BRAVIA KDL-52W4100 52 in. LCD HDTV - Page 6 Questions & Answers

Press the "WIDE" button on the TV remote a few times to change the TV wide mode settings until you get it to "FULL". If that does not fix it, look on your Cable box remote for an "Aspect" or "Format" button and press it a few times. I hope this helps.

Ensure that the TV plug connected firmly to the mains power supply, if nothing happens,
It is require of you to open the cover of the TV to check for blown fuses, if found, do replace with a new one of the same current rating.
if otherwise your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power suppply board just have dead leakages gases capacitors.These capacitors alway bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like, to buy a whole rerfurbish power supply board for the replacement.

If lines at 1/4 of bottom part of screen are across the screen then it could be T-Con or LCD Panel problem and if lines stop in halfway then its confirmed LCD panel problem.
Below exploded view (taken from service manual) shows T-Con board location in this tv.
Hope this info will help you.

NOT unless it is a DUAL frequency Standard, as Europe is PAL & SECAM, USA is NTSC. Also the HERTZ is different too 50Hz Europe, 60Hz USA, so really NO. IF it would work, it would have an international power supply, meaning it was usable any where in the world. and also it would have a multi tuner. Otherwise it will NOT go.

Servicing the unit requires a service manual , only with a fee.

I wish I could tell

you there was a quick fix or button to push that would fix

the TV problem but that is not the case or the solution needed to get

the unit operating correctly.

There could be many reasons. But, more Often, it would be

on the Circuits Board. You need to Open the TV, unplug the

wires from Circuits Board, pull it out and check it.

More often, you would find either a Loose Solder /

connection or Leaked / Bulged / Swelled capacitor. You

need to note down the part number and you could order it

online or go to your Local Electronics shop and

purchase it. Once you solder it, it would be all set.

Determine the symptoms; identify the cause of the symptoms;

repair the unit to eliminate the cause

Let me know, if needed further assistance.

Thank you for choosing FixYa for assistance. I hope that my

information proves useful to you. If so, please take a moment

to provide me with a positive rating. I'd really appreciate it.

The only answer is to trade your TV with my old 13" RCA with the rotary channel selector knob. You obviously were not prepared for the incredible performance and effects today's technology can provide.

Let me know when you are ready to swap.

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.)
