Wireless guitar system was working
This has the earmarks of battery problem... Supposedly this uses a 9 volt battery... You CANNOT use rechargeable batteries in these as the actual voltage of the rechargeable is lower than alkaline and they will fail quickly and as they age you may get only seconds of operation. When they go off the battery will recover a bit and even look like it comes on again. Do NOT count on the battery LED to give actual answer. When you turn on the unit, read the battery voltage under load with a meter. It should be at least 8.5 volts. NEXT possibility: A chronic problem with body packs is the battery contacts. There is a fine line between having good contact and being able to get batteries out. I have seen where people stuff paper in to increase tension on the contacts.

Yamaha P-250 Stage Piano won't boot up...
Yamaha pianos go through a self test on start up. This could indicate a problem on the main motherboard.
Try a hard reset.
Hold down top C key while turning on.
Wait for it to start up, if it still freezes its time to take it to the repair shop.

Fix Reverb unit on Fender Hot-Rod Deluxe Amp
Could have broken a spring in the reverb tank, or a wire connecting it to the amp, or the reverb driver tube, or a few other things, but those are the most likely in this situation. Thats what I'd check first. Give it a little slap and if it vibrates like normal, your spring is probably ok, you can still open it up and double check though. Check your wires. Then pull your reverb driver tube and replace it. If that doesn't work, it is probably in the circuit somewhere, and you should not work on your amp unless you know what you are doing. They store large amounts of electicity in the caps and they can kill you.

Why zoom g2 point blinking ?
There is damage/burnt at Transistor Q4 or Q3 or both. Usually followed by R8. Replace it.
Q3 = BC337 (SMD marked as 6C) NPN.
Q4 = BC327 (SMD marked as 5A/B/C/D) PNP.
R8 = 470 ohm (SMD marked as 471).

I have a stagepas 300 it turns on but wont produce sound
I once had this problem. Turns on but no sound. I tested the fan next to the power supply and it ran rough like it was worn out. I found the fan on eBay A5010L12S and replaced the fan. The Stagepas 300 came back to life. This fan blows toward the power supply and the other fan sucks air to create a circulation of air inside the mixer.

Hi my Marshal G15 is making an echoy twang
I suspect the vibration when it is loud is vibrating a reverb tank within the unit.
Test this bylistening with headphones and see if you get same sound.
It may be the reverb has a resonance or the cabinet does that is sensitive to your E chords.
The shock mounting of the reverb may have failed to isolate the reverb tank from speaker vibrations... hence the headphone test.

Sometimes the reverb works, then next day it
Fender Amplifiers are notorious for their reliability issues.However, I'm sure that amp will sound sweet once you get everything working again!
The problem is likely your "tank". The tank contains the springs which create reverb as the guitar's signal is sent through them. A broken spring could be causing your problem.
Luckily, any of the larger music stores should have them avalible.
Good Luck!
