I found this with a google search. I will put the link here to give credit to the site. This is not my own info. Full credit goes to the site owner.

• 3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

It is due to over voltage form the SMPS power supply to horizontal output section circuit. If this voltage goes higher than normal, the set will shut down, showing two blinks of standby lights. I've recently found one site that details all these matters well. "electro-help' is the site name. Google for it. have all details, and I'm sure that you will get all details.

HI,
By three blink it means the B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is because there is problem in the power supply circuit. Check for any dry soldering in the power supply side. If the tv is working properly for 20 minutes then its sure that there is some dry soldering joints in the power supply side. You have to resolder suspected soldering contacts using soldering ion and solder. The dry soldering joints will look like on in the picture.


ok

Hi,

May I know if the standby led light at the front panel is blinking, if so please count how many times it will flash to determine the error code? If not follow the steps below.

In standby mode press the button of the remote control in sequence, " Display ", " Channel 5 ", " Vol (-) ", " Power ". Self diagnosis screen will displays. Le me know the result.

2 blinks means - over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power supply of
any of the circuits.

the picture comes for 2 secs on the screen and immediately goes to stand by and red LED Sony bravia standby mode blinks 8 times

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.
