I will ask a question: Did you remember to power ALL inteconnected equipment from the SAME and I do meanALL and SAME receptacle or power conditioner module? If you powered your stuff from several receptacles in a large venue, likely ground system bounce has caused damage. I don't know what you mean by "dont get any signal in."... explain that... There are tests to run to isolate the problem but if you got hit with ground bounce transients you could have major damage. That is a big board for an outside venue so you might describe what you had configured from mics, etc. to speakers. ALL professionals know to run power back from where their amps are to the mixer alongside the snake. I will give you points for carrying a spare... ALWAYS a good plan as electronics DO fail and of course at the worst time.

Run the RCA cables into TWO channels of the mixer. PAN those two in opposite directions to create stereo signals inti and out of the mixer.

Usually this problem happens due to bulging of filter capacitors in the Power Supply Unit. identify and replace faulty capacitors with higher voltage ratings to fix this problem. Replacement of the capacitors is very easy if you have repair experience or at least soldering experience.

Above is your user manual below is a service and repair manual.

Indeed i would suspect something around your Final Output semiconductors, and any associated resistors?
You really must obtain a service manual, here there are the troubleshooting steps required to isolate and hopefully allow repair of your unit.
Look for any discolored components etc, check if any are overly hot... use a temperature probe on suspected components. Freeze spray may also be useful in diagnosis.
Use your eyes & nose to isolate the bad burnt overheated components, I sometimes use a straw up a nostril and selectively go over suspect parts, and "Sniff" to try and detect the overheated smell... it works.

I understand your pain - was googling for similar, and came across this post, 5 years prior. My SGC Nanyo Bass Collection has just started to play silly beggars with the pots, and a bridge fault. Nowhere online seemed to have any details of the wiring, as the problem is, as you say, the fact that all of the tone and volume pots are based on a printed circuit board. If theres a nick or short on the board, its a pig to replace, and I really wouldn't like to have to wire any pots onto it. I'm currently looking at the options of ripping out the old electrics and wiring it from scratch myself. If you're still after answers, good luck!

PS - noted that none of the previous replies are relevant to this - mostly going on about the amps or a Fender guitar??!

To verify, often the voltage is stamped on the back of the keyboard, near the power jack. Should say 9V

Can you please Edit or add a comment to your question, what make and model of organ is it? Have you tried it in a different AC outlet? Do any lights come on when you switch it on? Have you tried the headphone output as well as the speakers? Does it have a line output? What happens when you move the volume knob and or the swell pedal, do you hear any noise?

Have you checked that it is not the amp that is the problem? This is a fairly common thing to have the amp heat up and the thermal protection shut it down partly. Since the bass drops, a loose connection or bad guitar cable can cause that. If the signal becomes capacitively coupled only the treble will come through and be very distorted. Try a new cable. For the guitar, open the electronics area and look for loose or broken wire.
