Hi,
My Aria AS-690B Sinsonido has
First thing is to check that batteries are good. Next, verify your guitar cable is a good one... some are microphonic and the cable can actually insert noise into the signal. The plugs on cables can sometimes be noisy as they move while playing. Try to keep the guitar from "hearing" the amp as it can create feedback. Verify the amp itself isn't the source of the noise. Try a different guitar. The input of the amp is grounded by a contact when cable is removed, If there is a problem right in the input stage it can be masked. Plug only the guitar cable into the amp... Is ti quiet? If so make sure to try the first few suggestions. ALso be aware of other noise producers like fluorescent lights an dimmers... these generate electrical noise that sensitive guitars can pick up.

OK, plug in a cable, borrow a multimeter from a friend and meaure the output resistance on the other end of the cable, between the 2 connections on the plug. Should be between about 3000 to 15000 ohms with volume control flat out. Then report back here with your findings.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.
