    I have the same problem, 4 blinking lights and no picture. I took the back off to look for the backlight inverter. What does it look like and do you have a website where I can purchase the parts needed? Thank you

A 4 flash shutdown indicates a backlight problem. It can be acused by a bad backlight inverter board (the backlight power supply) or by a defective backlight in the panel. There are fuses on the backlight inverter board called "picofuses" which will need to be checked in order to isolate the problem to the board or the panel. If the fuses are good, you have to replace the panel (very expensive!). If the fuses are opne, most likely the back light inverter board has failed.

Hi,
4 times red standby light indicates problem with exhaust fan that is not running for some reason.
Recheck fan that you replaced and make sure its connector is plugged properly and it running freely.
4 times red light blinking is fan error in this tv.
Thanks.

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.

Sony Tv Problem


The 4 blinks indicate the problem circuit, but I need the model number to give you the specifics. The category you entered is KV-36fs120 which is a 36 inch set. Please update this with the model number. It should be on the back.
Thanks,
Dan
