7 times mean no horizontal deflection. So check horizontal output an solder of it and associate parts.Often resistor and transfo driver of base of h. output.

My sony trinitron xbr tv turns on stays on a few seconds then powers off by its self and it gives 5 red blinks from stand-by


This is according to the sony service manual

Five 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.

Sounds like a failure in the C Board or AKB Circuit.

Best to take it in to a service center.

Light blinks 7 times when i try to turn it on. sony kv 36xbr800


Are you sure it isn't eight......try turning on this method....display, 5, vol+, power on. Should bring it on in the diagnostic mode. Mine and about kazillion other owners have the same problem, bad M board and they never issued a recall on it. Costs 2-300 to have someone repair it, cause its' too heavy to carry it in, I think they used cement in the bottom for weight.

Tv wont fire up stand by light just blinks


Try this to see if you can get it to come on in the diagnostic mode. Display, 5, vol+, power on........need to do it in rapid order and sometimes you have to try turning it on with the power on then display, 5, vol+ then power on. Use the remote for this method. Will bring on the diagnostic mode and you will have green numbers on the screen and like we did, we got used to it......

36xbr800 sometimrs will turn on sometimes won't


it may be open contact on the flyback or
bad solder in standby power supply

Give it a smack open hand on the side
or better yet if you can have someone press
the power button as you rock it back and forth
this can tell you if its bad solder some times.
