Question about Televison & Video

1 Answer

Tried turning on my Sony and no picture no sound, just a black screen

My cable works but there's no picture. The timer/bystand light blinks and few times and then just stops. Please help!

1997 Sony KV-27S26

We have to let the TV warm up before the picture will come in.

Sometimes it takes 25 minutes and it is just luck that after turningthe TV on and off the picture will come in. Volume is fine, channel's are fine, the picture is perfect when it finally warms up.

We know the TV works.....just frustrating because we never know if the picture will come in. Jcrary@comcast.net

Sony is known for having problems with the picture tube. Sometimes it will blink on and off. also bad connections on the main board. A CRT restorer will sometimes help with picture tube problems but this must be done by a tech that has one.

Sony bravia KDL-37XBR6 wont turn on at all, and blinks 6 times..


The 6X blink code is a bad back light error. could be one of the florescent bulbs in the panel if it shows a picture for a couple seconds and there is a darker band across the screen. Also Found loose connector CN6153 on the G5 Power Board.
CN6153 goes to CN6702 on the D4 board. Or the power board

32 Toshiba TV no picture / bad pciture


Hello Suzid, It looks to me like you have a possible power supply issue (poor brightness on screen, shrinking of the picture, and initially no picture) This problem may put you in danger of electrical shock, so I would suggest that you not try to repair this set yourself. I would suggest that you take the television to a television repair shop.The power supply issue could be a low power or a high power supply problem.
