        Im new so if Im not suppose to reply forgive me but I have a Magnovox 46 inch 14 months old doing the exact thing. I bought it for $50 to repair from a friend. I can plug it into outlet in the morning and turn it on with remote or switch on tv but if i turn it off after even 5 mins with remote or switch it will not turn back on . The stand by light stays on but does not flash or anything but i can unplug it for 30 mins and start it back up again but its the same process. It will play for as long as you leave it on but once you cut it off it will not turn on until its been unplugged at least 30 mins. Thank you for posting maybe we can both find the problem.

          First of all you'd need to find out if it is the power supply or the mainboard that is at fault.
          Monitor the ps-on signal form the mainboard and see if the mainboard is trying to turn on the power supply.

              Sry Tom. Made new thread because fault changed from title in first thread. Tried to delete original one but was unable to.
