I have a Sharp that shuts down on its own. Sometimes it will last for 1hr. some time only for a few mins. Two things I notice are that it will not come back without unplugging it,and when it goes off there is no voltage out of CPU to turn on relay drive. I do have the drop in the 5volts from the on button to the CPU. I dont have a schematic of this one as there are not too many Sharps around here ,so I'm working in the dark. Does anyone have any notes on this as I don't want to change CPU as it is a flatpack anI dont have the facilities for them. I am just wondering if it might be an xray shutdown. Is there anything in winstips on this. any help would be appreciated. Buck Pasher Buck's TV Gander Newfoundland Canada 709-256-7738 (Fax & Phone) --- Outgoing mail is certified Virus Free.
