One of the components within the Picture Board blew something, please take it to your Authorized Sony repair person and have it fixed.

Hey,

Let me know how it goes.

I would look for intermitent solder connections on the small horizonal driver transformer as well as other HV Componets.(HV Transformer etc.) Also solder up the Vetical output IC. These have been common causes of failures. I would not use the set until these have been checked and soldered. If you don't, a massive failure of the hoizonal circuit and powersupply will occur.
Hope this helps,

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.

Hope this helps and Good luck.

Try changing the input device to something you are sure, works such as a DVD player. If result is same, if this is an LCD TV, show a flashlight (torch light) from a safe distance on the screen and check whether you can view the picture. If you can, the backlight is not getting on. A case to be handled by a qualified service technician.
