I have a Kicker ZX750.1 that I have been running for years without issue until just recently. Lately, it would intermittently cut out. Yesterday I noticed it was not coming on at all so I decided to check it out. The red light will come on for a couple of seconds when I turn the system on and then the light goes out. The red light will also come on for a couple of seconds when the system is turned off. There is no light at all in between those times. I checked power, ground, and remote and they checked out ok. Nothing has been changed with the system. Any ideas on what would cause this or something else I can check? I would like to fix this myself if possible but I am fairly ignorant on the inner workings of an amp.
If you're new to repairs, read through the following page:

Don't take the amp board out of the heatsink yet.
