Auto off my sony trintron 100hz, switch off automatically. One of the light at the front right bottom blink occasionally. i've to power off the tv, then on. it work for another 1 or 2 minutes. This continues for about 20/30 times. but sometime it work fine. please guide about it.

1. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative). If you wish to get more details about the blinking codes to Sony brand TVs, check this link. Pull up older posts there.

count the blinks on the power light--most will have a error code where the power light blinks a specific number of times---does not point to a specific part but indicates what area problem is in.

standby light blink 7 times

I already seem this on that model and it was a short diode D503 part # BY228GP.

looks like a horiz.output transistor is shorted.check it...

Since the set recovers under some conditions, I would first look for poor solder connections. With a set of your vintage, it is common for some of the connections to become faulty. If you can solder, resolder any connections on the board that appear grainy or have rings. Please note that there are potentially dangerous high voltages present inside the set even when unplugged.

Keep us posted on your progres.

The 2 blinks is a diagnostic code that should indicate the problem circuit. This is unique to each model though. Can you confirm that the model in question here is KV-32FS120?

Thanks,

it sounds like a b+ cap going bad and is intermittant that feeds the the video drivers on the crt pcb or the crt is shorting.
