SOURCE: Sound through right speaker is not proper Creative Inspire M2600

This sounds like an electrical problem in the speaker circuitry - between the speaker(s) and the control knob.

SOURCE: Technics SA-DV290 Amp. Sound cuts out as volume is increased

hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

Make sure this is happening from two sources such as a dvd player and a gaming system as well. If it happens from two sources the speakers are more than likely not working or the sound board will need to be replaced. A cheap way of getting around a repair is by getting a surround sound and running a cablebox, dvd player, and/or your gaming system directly to the surround sound system using it for sound instead of the tv.
