Hi everyone,
Just want to see if anyone could help me with how to go about fixing an upa 500. About two week ago, my upa stop working after lightning surged my power line. Now my upa go to protection mode after i press power button, red light keep flashing. It already ran out of warranty!!!!
Have anyone had that issue before? If yes, how did you fix it?

Lightning can do serious damage.
Unplug and let it sit for a couple hours before opening the case IF you decide to check fuses.
While you are in there, LOOK for any burned traces or cooked 'stuff'. Use your NOSE, too.
If replacing popped fuses doesn't work, you need some Serious Technical Help.
Do NOT use any fuse of a higher rating than what comes out of the amp.
Do NOT use slow blow where a regular fuse was.
If you live in a lightning prone area, you MIGHT consider a whole-house surge suppressor.

My XPA-500 has blown fuses twice over the last 5 1/2 years. Mine just stopped working on all channels and the front lights stayed on blue when on. Replaced the two fuses that are closest to each other both times--left other fuse alone (I think I called Emotiva the 1st time and was told if 3rd fuse blows light will not work). This fixed the problem both times--but my issue was not exactly like yours since my light did not flash red but stayed blue. Hope your problem is as easy to fix as mine was.

Thank you

I’d suggest checking the fuses first, if they look ok then my next step would be to disconnect everything from it, leaving just the power cable and see if it powers up then. If it does that means something else is casing the problem, so try connecting them one at a time.
Cheers

IMO, Fuses should be checked with a METER. Some higher current fuses 'pop' with enough evidence that it SHOULD be obvious.
Lower current fusess, maybe 4 amps and under, can sometime just go 'open' without easily visible signs.
Ceramic fuses should ALL be checked with a meter.
A meter is your best bet....and ONLY for those fuses removed from the circuit.
