Does anyone know how to troubleshoot the T-Conn board on a Sony Bravia KDL52wl130?

I have ruled out the PS board, the TV drops the 3.2 v to the back lights.

Sony Bravia model #KDL52WL130 worked fine for first year then picture went very dark for the 1st 30 minutes it was on but eventually cleared up. Now it takes longer and screen is completely blank. Sound...


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years, some sooner, because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

No picture or sound. Red light blinking four times on sony bravia tv. Suspect power supply problem?


Red light blinking 4 times on Sony bravia TV.This is the problem of INVERTER BOARD.The inverter board has to be replaced.Every Sony bravia tv has a particular model number and the Inverter board part number depends on model number of the tv. As you have not mentioned the model number so the exact part number of the inverter board is hard to tell.But you can get the required inverter board part for your tv from www.partstore.com ----------- Thanks. Keep updated for any more query. You can rate thissolution and show your appreciation.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Buzzing/fizzing noise from back of sony flat screen tv


Below is an image of rear side of your TV, Sony KDL-40W5500
Top right corner is marked there and possible cause of noise seems back light inverter board, there are high voltage going to CCFL inside LCD panel and seems high voltage leakage causing that buzzing/ fuzzing noise.

Replace back light inverter board upon voltage leakage confirmation.
Thanks.

I'm getting an invalid format on my hdmi inputs when i hook up my ps3. It's wierd because it works on my viszo, but not on my new westinghouse or my samsung.


If you accidentally set your PS 3 for 1080p resolution, when the TV can only support 720p, you get a black screen. The Westinghouse TV I used displayed a message that said "invalid format." To reset the PS 3 to the standard AV format, you shut the PS 3 off. Then you hold the PS 3’s power button down for about 10 seconds. It will reset to standard video

Toshiba HDTV + SONY PLAYSTATION 3 + SONY Home Theatre DAVHDX265


I have looked up the infomation on your TV I noticed that your TV has two HDMI input plugs. Since your SONY BRAVIA is hooked up to one port, you need to buy another HDMI cable for your PS3. On your tv remote you should have an option to switch from video 1 to video 2 so then you can switch from the SONY BRAVIA to the PS3 the problem is you will only hear your PS3 Sound from you TV. If you want to hear your PS3 sound from your SONY BRAVIA you need to buy an optical cable (also called TOSLINK) to connect from your PS3 to the SONY BRAVIA.

Hope that helps!
