It sounds like you may have a power-supply problem. You need to measure the DC voltage across the B+ and ground terminals of the amp. If it doesn't remain near 12v when the amp is on, you need to determine why the voltage is dropping. It could be due to a defective fuse or a corroded connection at the battery.

Ok, i love the tones on this amp, but for some reason, i start to play, not even on at a high volume, just like at a nice level, ill play it for like 5-8 mins and it will shut off, like the power is still...

This is a tiny amp good for practice at low volume levels. You are likely overdriving it and the power amp chip goes into thermal protect. If you volume level is much louder than a small boom box, you are driving it too hard. Best to get a bigger amp.

-it is a power problem. -i turn on my ps3 system using the main power button on the back of the console and the red light comes on in front. -i then touch the standby button in front and the red light...

You can fix it yourself. The CPU was to hot and the solder has come off. Bad part is the solder is under the CPU and must be heated up. It is lead free so it needs more heat then lead and you need to add flux. I would start by getting the board out. Remove the thermal paste off the CPU. Add flux with a flux pen. You want to get the flux under the CPU so you might want to tip it on its side. After you have a good amount of flux under the CPU you want to start to heat the parts around the CPU. I would use a heat gun with temp. settings. You first want to heat around the CPU to keep solder on the other parts from cracking. You dont want to over heat the parts. After you preheat the board you want to heat the CPU. It needs to be around 400 or 500 degs f. a good 15 or 30 sec. keep moving the heat gun. After heating the CPU you want to start the cool down. Same as warming up the board but you want the board to cool down slow. After all this you want to add New thermal paste to the CPU. This helps transfer from the CPU. This is a must because your PS3 is overheating as it is. After you do all this some people say it only works for 2 to 6 weeks. Its all on how you fix the board and how good of a job you did. I would back up your hard drive. Then hope for the best!! good luck and i hope this helps you out.

When I turn on my Playstation 3, a green light stays on and then the fan goes into "Turbo Mode" for about 30 seconds, the Playstation 3 beeps 3 times and the green light blinks. -No yellow light appears.

have you ever had the playstation taken apart? Maybe you need to replace the Thermal past on the processors. It is due to an overheating problem. I have one right now that does that.

Disc stuck and then Ps3 system when turned on goes from green to yellow then blinking red

PS3 has overheated and the thermal compound between the cpu/gpu and heat sync need to be replaced. the gpu and cpu may need to be reflowed as well. Had the same problem and fixed mine. The thermal compound was pretty much gone when i opened up the system. Also dont keep your ps3 on its side leave it flat this will help keep the compound from moving as much.

Press power button green light comes on.But no picture no sound,

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

Amp cuts out

Check your ground wire that's more than likely the problem.Try grounding it in a different spot make sure your ground is a paint and dirt free surface also make sure its directly metal to metal.

The yellow wire goes to + (hot) 12 volt constant, red wire goes to ignition switch, Hook up your amp together with the red wire
(switched) and the amp will come on with the ignition switch.
Blue and white wire is for the power antenna.

I have a xm6660.... yellow light...

There are some things I want you to check, 1) Make sure your ground is good and I mean very good, 0 ohms resistance to the negative battery terminal 2) Make sure that your AMP is grounded to that ground point you checked in step 1. 3) Make sure that your power supply B+ wire is one continuous run no taps or spliced connections. 4) Your speakers and woofers are all properly impedance matched to your amplifier (if your amp is 8 ohms then your combined speakers impedance must be 8 ohms total). 5) voltage regulation to amplifier is good. 6) Check all connections and ground points again After these items are done power on your unit and then see if the problem happens again, if it does the issue is inside of the unit, one of the internal components has gone bad and you will need a schematic, a multimeter, and an audio tracer to work on the AMP with.
