You have some semi-conductor device that is effected by heat and is faulty. When it get's to hot it switches off, then it cools down and comes back to life. If this is a stereo amp and it happens on both channels then you are looking for a device that is used by both channels. The only way to find out which part is to use Servisol Freezer Spray on suspect parts. You wait while it plays up and then blast (only one at a time) the suspect part with the spray. If it comes back to life you have found the part that's faulty.

SOURCE: problem with my Peavy CS 1200x power amp

The Idle bias or channel offset circuit is not functioning and the longer you wait before you have it repaired by a pro, the more its gonna end up costing you. At this point its probably just a small bias diode or even an channel bias alighnment .Good Luck

Output transistors or the preceding driver stages may be failing. Check for electrolytic capacitors for bulging tops, they will have to be replaced.

Rutabaga, The most common reason for intermittent power is a small IC chip on the backside of the I/O board which is attached to the rear housing of your unit. If your unit's warranty has already expired I would recommend the following. This is at your own risk. Grounding yourself is recommended. 1. Take off the antenna by rotating it as far counter-clockwise as possible (all the way up) and pull it off. 2. Take out 4 screws 3. Hold both front housing and rear housing with and gently pull the two housings apart. Once it's barely opened unplug the RF cable attached to the corner of the main board. It will either be gray or black depending on when it was made. 4. The other end of the RF cable is connected to the I/O board attached to the rear housing. This is the board that has the small IC chip that rubs against the rear housing which causes it to come off. 5. There are 6 or 8 small screws holding the I/O board to the rear housing. Remove them. 6. Once you got it off, look at the back. On the bottom backside of the I/O board next to the metal heat shield there should be 3 small IC chips. The lowest one is the one that rubs off. If the IC chip is present try looking at it through a magnifying glass and even push it a little bit to make sure it's not loose. If the IC chip isn't there, then look around for that rattling piece. (Either way I suppose look for the cause of the rattle) Soldering: If you find that the IC chip is loose, then you will need to solder it back on. This is not a lead-free unit therefore you can use lead. If you do not feel comfortable doing this, then atleast you have found the problem and can take it to an electronics shop for them to solder it back on. If you feel comfortable doing it, then by all means knock yourself out. If you have any further questions then please ask before proceeding. -Daniel

USUALLY if the output transistors go, they stay gone. You may have a thermal cutout switch shutting off because of over temp. Make sure fans and heat sinks have free air flow. I have seen broken solder joints in these near the volume pots. Those can also cause a failure as unit warms. When it stops again, let it sit without playing for say 10 minutes and see if it comes back on... if it does, the over temp sensor is probably shutting it down so it doesn't fry. Is it possible you are driving it too hard? Often people try to get more sound level out than unit can deliver.

Video output settings

You might have to reset your display settings. You will need to turn off your PS3, Holding down the power soft key, turn the unit on in the back. Keep holding the soft key until the unit turns back off. Wait for about 15 seconds. Press the power soft key again. You will hear one beep, then a second beep. Then you will hear 2 quick beeps, as SOON as you hear those two consecutive beeps, let off the power soft key and a screen should come up to reset your display settings. Good luck!
