Hi,

I am trying to repair a Philips receiver 70FR260 or FA260. It had shorted
clamp diodes and open control transistor for the power relay. I replaced
them, but still the microcontroller does not wake up.
If I pull down the micro output, the power relay turns on the set. All
supply voltages are present but the display is dead. Also removing the back
up batteries for a while didn't help.
The micro controller oscillator is running, all of its signals seem to be
ok, including the key scanning pulses. So its program is probably running.
I would appreciate suggestions to wake up this stubborn receiver!

Best regards,

Gerhard
