VIZIO flickering Tv screen easy fix( no money ) .... I left town unplugged the Tv. When I came home home ...
Failure of the vertical deflection module/circuit. The tv will have to be opened, the vertical deflection circuit found and replaced.
Definitely a job for a pro - the circuit is going to be extremely difficult to extract. The repair will cost you about $200: $20 for a new circuit and $90 per hour for the 2 hour job.
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

I have Sony KDL-32XBR9 and I have noticed a similar problem. When the picture is showing mostly black, for example during the ending credits of a movie, the TV will further darken the display. Once the picture lightens back up, the TV will adjust the brightness of the display back to normal. I just called Sony customer support and they indicated it was a firmware problem and they will be sending a USB device in the mail to update the firmware. Hope this helps.
