SOURCE: Sony BRAVIA KDL-46V3000 Television goes black

Hello,

This issue is related to a power problem in as much as the TV turns off on it's own. I think the TV has developed a power problem.

The problem is consistent with overheating on the power supply board of the TV.

The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.

When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.

This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

This is a common problem faced by many other users too. To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply board.

Sony specifically uses GM1 Board. In other words, Sony power supply board is called "GM1 board"

It's a bit technical job but yes its not at all a costly repair to do or get it done by the technician.

You can buy this part at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor (capacitors) most likely the normal operation will be restored. Or you can buy a refurbished complete GM1 power board from shopjimmy.com to save you some stress.

If this task is too technical for you, you can call a family or friend who has the ability to assist you (two heads are better than one).

SOURCE: the screen lost horizontal then vertical lines ,

Hello,

All plasma an LCD ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken....
Also note that the power of the television could be at fault in this regards you have to follow
the instruction that i will provide below

Your power supply board is not yet dead, you must have knowledge on basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this help in solving the problem....

SOURCE: sony bravia l42" LCD TV. No power. Green light on

7 blinks in the this series(KLV) means there is a short in the power supply board. The easiest way to fix this would be to swap out the board. I can find you a replacement if you want to try fixing this yourself.

Sai.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
