When i turn it on..autosearch starts after a few minutes and sometime volume rises up ...help me plz

The most common cause is damage to the volume potentiometer.
Replace it.

No real clue on your problem, but try plugging your PS3 to a surge protector or an Uninterruptible Power Supply (UPS) because it's bad to have it directly plugged in to a power outlet.

could be a weaf water pump also check or replace radiator cap

This is often caused by a defective tact switch on the front panel. With the system turned off, try puching all of the switches on the front( except power on). You should feel the switch engage. If not, then the switch is likely to be faulty and require replacement. Parts cost should be in the $5 range.

First, swap the speakers to see if it stays with the speaker or the amp channel.

Second, disregard the throretical ability of any speaker to handle any amplifier's maximum output. Amp ratings are at a certain power output with a certain amount of distortion. Turn the volume a click higher and power output might rise just a tad but distortion starts to go ballistic. Continue and you get total high current garbage. Clipping (high DC output) will kill any speaker.

Since it seems to go away, I doubt the speaker is damaged, unless torn speaker cone or burnt voice coil can self-repair in a few minutes every time.

Need more information on this if possible.

It may be the speed volume is enabled on your radio, does it fade out when you start to come to a stop? Some vehicles have a speed volume setting in their radios in which the radio raises and lowers the volume during driving conditions, like when your comming to a stop, the volume will automatically lower and during faster driving speeds will rise to a higher volume.

If you check at the back of your hi-fi, you'll see a projection at the top where the cooler fan is located. The most likely reason is that your fan is not working (as required). In this system, the fan is turned on automatically at high volumes >=10, because then, the amplifier starts to get a temperature rise and without proper cooling the system might fault.
Try check and see if at these high volumes the fan is running, if not, then that's what needs to be fixed. Alternatively you can try running an external fan to see if it will produce the desired cooling effect.

Check your Processor FAN and Heatsink lock if the heatsink firmly sit tight on your processor, sometimes the heatsink lock is lossen making the processor extremely heat and shutdowns automatically, if its ok, then try replacing your powersupply.

Two things I think are happening. It is overheating and it has suffered some sort of damage to a component inside. Try to make sure there is ventilation on all sides. Can you remember a time where you did not have adequate ventilation for this device? If so maybe that is what caused the part inside to fail.

Hope this helps

Thanks for reading!

The tact switches on the front of the unit are going bad, need to replace them internally.
