Hi I have a Toshiba 36zp18q, the set is two and a half years old and up until now I have been very happy with the it. It has now developed a problem where as it is stuck in standby mode. After many attempts it turns on but this is getting worse. When it does power up it sometimes sticks when switching from EXT 1 to EXT 2 etc, sometimes after 5 mins or so it corrects itself but more often than not I have to turn it off and then am unable to get it back on. I have been searching on the net and have read of other similar problems and have read of cases where a new microprocessor has been recommended at gbp300.00 plus. Can anyone offer an advice I am new to this forum so apologize if this has been highlighted before. many thanks for your time.
