MC-8 was working fine within several years and on one day something happened and it started to occassionally 'reboot'. This looks like when you start to watch the movie/listen to audio, everything starts fine, but it takes 2-5 minutes and MC-8 'reboots' and runs diagnostic tests. When they are passed, they start over again, this process is similar like you power it on, then power off and power on again. I tried to turn it off from standby mode, let it get cooled and turn on again. It worked a bit longer but then started to do resetting all the time again. I changed the power cord, tried to plug it to another outlet, but it gave the same result.
The only difference that I was able to catch is that when I took it away from all the devices, disconnected all the wires and just plugged it into the outlet without any input/output and turned on, it worked fine during several hours so I started to think that something was wrong with the outlet. But when I returned it to the usual place, connected to DVD/amplifier, everything was the same, it started rebooting after the small amount of time.
Can anyone help me troubleshoot this? Is there any way to return it to normal working condition?
Thanks in advance!
