Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

The usual cause of this is the sensing IC (there are 2 of them) on the power supply board. Sony usually recommends pulling the board and returning it to them for service.

Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.

Hi, this is a very common failure, you need to replace 2 IC chips on your power supply board, marked on the top of the IC`s is this number: MCZ3001D you can purchase them here if you are very proficient at soldering & un-soldering, and the board has to come out of the tv to do this, you might want to call a tv man for this one, but it will fix your set, happy holidays, BMW Rider
