I have an IED 11
Good job of troubleshooting... I assumed you have tried other triggers into the kick drum input and found it is dead. This leaves the problem in the "brain". Look in your manual for anything to do with sensitivity of the kick drum input. It is likely all the inouts are sampled and digitized by the same A-D convertor via a multiplexor switch. I was unable to find the schematic of your unit so I downloaded one for a Roland TD8. Often the different companies rob designs from eachother so one can glean methods from a different brand. As expected the inouts are conditioned and then go to a MUXX chip that samples the input. The signals are conditioned before going to the MUX by a limiter and before that there is an RF bypass cap on the input. IF you might have had a static discharge, that capcitor(s) may have shorted rendering those inouts dead. This is what I want you to try:with a suitable cable I would like you to pulse the kick input by momentarily connecting a 9 volt batery to it... try both polarities. If NEITHER polarity fires the kick, then I want you to take an ohmmeter and measure the resistance of the input. The Roland schematic has coupling capcitors and if your brand has similar circuits you should see infinite resistance... if you find it very low, say 100 ohms, probablly the RF bypass cap at the input is shorted. These will be surface mounted caps and you need to be a bit adept at electronic repair to replace them. Essentially I believe you will find a failure in teh interface ckt where those inputs come in.

Electronic circuit diagram for a bass collection bass guitar Japanese 1988
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??!

MY ORGAN HAS NO SOUND
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?

After about 30 minutes of
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.
