JBL Amp P80.2 - Random output failure

At random times my Amp will stop putting out any sound. The green LED turns off and the red LED lights up.. The amp will output sound at a low volume then when I turn it up it cuts out back to the same problem..
However this problem is not consistent and randomly comes and goes since I have recently re-installed it, it can be working fine then the problem just occurs again, and randomly fixes itself after a while ! Anyone any idea's how I can stop this problem occuring ?

I had an amp that did that for a while before frying. its possible that it could be overheating causing it to go into protection mode which can be fixed with a cooling fan or remounting it somewhere else so it can get some air. it needs to be mounted in a way that it will have at least 1/2" clearance under it so it can have plenty of airflow. the other thing is you may be putting too much of a load on the amp causing it to go to protection mode. check and see how u have the sub wired and if the amp is stable. if u have the sub wired at 2ohm for more power output and the amp is only stable at 4ohm, then the amp will overload and cause the problem your experiencing. thats what happened to my amp. i had it wired for more than it was stable for and it fried

I have a JBL S120PII sub that stopped working. All I get is the red and green light flashing on top. Is this indicative of a specific issue?


Check and replace the power output MOSFETs [at the power amplifier circuit]. A damaged MOSFET can cause this continuous LED blinks. It is important to replace all the 4 MOSFETs at one time. Also, check for any further damaged to any other components too have occurred. Contact any service technician. If you wish to get some details; check the site linked here.

Omnibook 6000 will not run POST. Has LEDs permanently on


When was the last time a BIOS update was done? See if one is available for this laptop and give it a try. FOLLOW THE INSTRUCTIONS TO THE LETTER WHEN DOING THIS OR YOU CAN RENDER THE LAPTOP INOPERABLE!! If youre not comfortable doing this, have a service technician do it for you. Sounds like the problems really went into overdrive when the new drive was installed.

It's likely that the amp has blown output transistors. To eliminate other possible problems, read through the following page:

You programmed it for usb interface, but the scanner is keyboard wedge. Try pointing the scanner at the "recall defaults" barcode in the manual as you plug the scanner back in.

No Output from amp, green LED on


are you absolutely certain your subs are in good shape? have you put a meter on them and measured the ohms as you depress the cone [causing the cone to move up and down on the pole of the magnet? do the ohms stay constant? go up to infinity[ suggesting an open] or go to zero or close to zero [ suggestting a short] both of these conditions will result in a zero or a very limited output from your amplifier, while still showing a green status light, if or when a full short or open occurs on the subs, a fault led will become lit, and whet that means is that u have fried the outputs....do a bit more testing with your vom....and good luck or try another speaker for testing purposes...
