Question about Sony FD Trinitron WEGA KV-32HS500 32" TV
It started about three weeks ago. I wasn't able to turn on the TV with the remote or the power button on front of TV. No sound or picture, just 7 blinks (sometimes 6) of the standby light, pause then 7 blinks again, etc... . After a day the TV would turn on again. Then it wouldn't come on for a couple of days, but would then work for a couple days. I'm now on the TV doesn't turn on cycle and it's been a week. Please help.
7 flashes is horizantal deflection stopped.
There is apparently a service bulletin, Service bulletin E28041743, that the general public is not privy to which further explains the common D board faults. The D board is what I replaced two power transistors (1RF1B7N50A) and 1 18 pin chip (SHINDENGEN MCZ3001D 03525) on.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.
