Sony KV-HZ29M65

I have a Sony KV-HZ29M65 TV, about 1.5 years old.

Recently this TV turned on for a while with sound and no picture at all, and then shutdown and the lamp indicator, blinking 10 times.

After some checking, actually accidentally, I can turn the tv on. It is happened when I measure the voltage at pin 2 or 3 or 4 of IC8002 (MCZ3001). It's running normal, can be turn into standby mode and being turned on again. But if I unpluged the tv from the main power, or turn it's main power off, the tv can not be turned on again. It can be turned on again if I unplug its main power, turned it on (it would go to standby mode) and turned it on with remote control (the audio would come up, no picture) and touch the pin 2 or pin 3 or pin 4 with the tip of multitester lead. (The other end of the lead is open.)

Thanks, Agusril
