Sony TV Error Code - Seven Blinks

You try to turn on your Sony TV and nothing happens. Then you notice that the standby light is blinking. Counting determines that it is seven blinks about a second apart followed by about a three second pause.

Your problem is that the B+ (high voltage) is over the normal maximum value. You have a problem in the power supply regulation and horizontal circuit. It more than likely is a bad solder joint. Solder all the connections in the high voltage area. This is the area around the flyback transformer.

The flyback looks like a can and is at the rear of the TV in a Sony. It has large red rubber wires comming out of it. One of the wires is connected to the CRT near the top.

If this does not solve the problem I have a tip at http://www.fixya.com/support/r4916851-diagnosing_repair_tv_high_voltage which should be helpful to troubleshoot the problem.

If you cannot locate the problem or do not have the necessary troubleshooting skills a better plan may be to purchase a new circuit board.

Fortunately these days circuit boards are not that expensive. I would recommend replacing the defective board. The board with all the power supplies in a Sony is generally the "A" board and contains the High Voltage power supply.

Two of the best places to get the board are http://www.encompass.com or http://www.shopjimmy.com . Prices are similar but both sites are trustworthy and will allow you to return the boards if they are not the problem.

If you haven't replaced a circuit board I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which explains the process and should be helpful to complete the repair.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.
