Question about Sony FD Trinitron WEGA KV-36XBR800 36" TV
Several people seem to have this problem. Mine is the same: "standby light" blinking when tv is off and it takes several tries to get tv to power on. Today it took about 20 tries to turn tv on. Help!! I'm no techie so please keep in mind us simple folks. Standby light blinks 7 times in a row. Attempts to power up fail each time. Unplugged TV after first hitting the power button but before TV turned itself off again without success (this was suggested by people at Sony). Still can't get TV to power up. Standy button fashhes 6 times when off. Takes several tries to get T.V. turned on. Usually about 3 tries, but yesterday it took about 20 times. What do the flashes mean and how can the problem be fixed?
I have spent about 4 hours tonight researching several tech sites and the Sony service manual for the same problem with my Sony KV-32HS510 unit. I was able to download the manual from a website http://www.eserviceinfo.com/downloadsm/31649/Sony_KV-32HS510.html and a TV Repair training lecture paper at http://www.repairfaq.org/sam/tvfaq.htm#tvhvp .
These TV sets have a safety feature where it will shut back down if a high voltage is indicated. Unfortunately, the electronics for these safety features are not very reliable and give false indication. Letting the unit sit off lets the capacitors leak voltage as well as cool off. These two factor help with the unit not falsely indicating a high voltage condition.
The D Board seems to be the most common failure component, but a 6 times flash could be an overcurrent/voltage failure from the A, B, or M boards. A 7 times flash is a Horizontal Deflection Stopped error with no additional information given in the manual for a fix. Again, in most blogs, the D Board seemed to the source of the failures.
A refurbished D Board part no. A1300319A can be bought for around $200 with a new board at $550 per the www.partstore.com site. Then add $100-$200 for an actual TV service technician and you have a repair bill approaching the costs for a new flatscreen TV.
Some tech types posted that they have actually repaired their boards by replacing individual components for around $40. You may find a service shop that can do the same component level repair at the $100-$150 level cost. It turns out that the closest authorized Sony repair shop is 2-1/2 hours away from us. Good luck finding someone close by.
We were able to get our TV to come back on after dozens of attempts and plan to leave it on until it dies all together. I may attempt my own D Board replacement when the time comes.

I think I have the solution for you. I have the same tv and it does the
same thing when you turn on the power button on the remote when the tv
turns on you hear a click then the red light flashes about 5 to 6 times
then the tv comes on. on the remote there should be two buttons on top
of the remote one says power and the other one says system hit the
power button to turn on the tv when you hear the click and see the red
light flashing then hit the system button which will turn off the tv
then hit the power button again and it will turn the tv on without the
red light flashing it should work
