Hi Again
Just got another one of these sets in for repair with a similar (but not quite the same) problem. Thought it might be worth comparing with your specimens. Set was stuck in standby and no amount of cable removal would persuade it to start. Found that if I heated the area around IC U696 (MP1583) with a hairdrier the set would operate normally. U696 is located on the top right hand edge of the signals board. Turn off and leave for ten minutes and it was back to the standby problem. Got the impression that this 8 legged step down regulator chip might be faulty. Interestingly it supplies the 3.3 Volt rail for the eeprom which could explain possible eeprom corruption or damage. Never quite sure using a hairdrier though as the heat seems to spread out a bit so guess replacing the IC would be a starting point. Don`t know if I`ll get to try though as the owner is considering his options!
Hope the info might be usefull.
Regards
John.
