Power cycle the unit and it will reboot and display for a while. The
longer the power supply is unplugged, the longer it will play but will
eventually shut down. Overheating? took the unit apart and could not
find a fan that might have went bad. Could power supply be heating up
and failing? I am trying to find a compatible power supply to try but
the plug is an oddball type. Model is SV1011. Seen that SV811 and ev1011 have same problem
Same exact problem here. I don't think it's the power supply, because if I leave the unit on and press the reset button (using a paper clip through the tiny hole on the back), I can get the configuration screen up. The unit, however, will again shut down a short time later. I fear this unit is toast because getting it repaired out of warranty would probably cost more than buying a new one. In fact, I've already bought a new one (different brand, obviously).Same exact problem here.

The unit is drawing too much power and is being protected by a current/temp sensitive device that shuts down to protect unit. When it cools, the power is restored until it heats up again, and the cycle continues.
Sounds like something in the power supply area is the cause of the anomaly.
According to your information you gave you either have an extended circuit (electrical) or a short/weak connection in the unit. If you can get to the outlet for the unit, try another outlet (different circuit would be better) this would rule out the electrical issue, either the unit or the power supply to the unit could be the issue. If you can you might want to call a subzero tech to look at this. This units main power supply into the unit is located in front on the freezer compressor, if you have a dark or blackened molex connection you would have a short there. Try the relocation of power first and see were the issue can be isolated to supply or unit.
Good day, The problem you describe is probably due to a faulty power supply. The four pin connector which you unplugged supplies power to the CPU, which means you will not be able to get a display with it plugged out, as there will be no power to your CPU. The fact that the PC does not shut down when removing the 4 pin connector strengthens the evidence that your power supply is faulty. By removing the 4 pin connector you are reducing the power required from the power supply to the point where it is not 'overloaded' enough to switch off. You can test this by plugging in the 4 pin CPU power connector, then unplugging something else, such as the DVD writer. Then switch on your PC and see if it still shuts down. If it remains on then the cause of your problem is definitely the power supply. Replace the power supply and make sure it has a wattage rating of 400 watts or more. These power supplies are relatively cheap, and should be available at your local PC store for about $15. Best wishes, Graeme.
Shut down
Unplug the power supply. Remove the battery. Insert power cord
Reboot with power cord but no battery
If it comes up, your battery is dead or weak Replace the battery.
If you don't even get a flash, your power supply may be bad. Get a new power suppy.
If it continues the restart cycling, then there's something wrong elsewhere.
I would check fusable link on power supply 12 volt DC from battery voltage. if compression springs loose inside link, possible that bumps are causing loss of contact causing power down, then when the reconnect, you get reboot, check entire power supply line from point of power connection to unit.
pow5 - your receiver has an internal problem, most likely with power supply unit. As soon as macroprocessor detect the power problem it shuts down the receiver. Check the power supply at first.
It sounds that you might having problem with your power supply unit,
try replacing it with another working one. Problems like this one can
be caused by defective power supply unit.
A couple of possibilities: the bad electronics unit might have power supply problems, optical sensor problems, or other problems with the electronics.
If you have some tech savvy and a voltmeter, you could check the power supply voltages. This circuit is likely in the close vicinity of the fuse. On the output side you should see a +5 volt, +12 to 15 volt, and perhaps a -35 volt (approx). The +5 supplies the logic circuit, +12 the motors.
If these voltages are missing, or way out of tolerance, you will have a dead unit. A frequent cause of problems in the supply is bad electrolytic capacitors, especially in the older units (Panasonic manufactured rigs, late '80s/early '90s). Possible values on these capacitors: 2200MFD/10V 1000MFD/16V and several others. Replacements can be supplied by MCM electronics, Mouser electronics. I use the Panansonic FC series from Digi-Key Electronics.
Sensor problems: Many VCRs have the sensor opticals mounted on the main circuit board, and locate themselves in particular spots in the mechanical section. One or more sensors detect tape loaded, one each for the supply & takeup spindles. If any of these sensors (especially the supply/takeup sensors) are non-working, the logic circuit will detect an error condition, and shut down the unit or at least put it into a stop mode.
Disconnect speakers one by one and reset the unit each time. If the speaker is blown, or the wires are frayed, it will shut down the internal amp. Also check the fuse in the back of the radio first, it should be near the wire harness. Power cycle the unit as well, unplug it from the power source, plug it back in. Hope this helps.
