I have an unusual problem. I have an Onkyo TX-28 receiver. When I got the unit I connected it up and the right channel put out distorted overdriven audio and the left channel had no audio. I looked inside and the left channel fuse was blown. I replaced the fuse now the right channel has no audio and the left channel puts out the same distorted audio. When I remove the left channel fuse it reverts back to its origial state. Quite a puzzle. Thanks! DJ...
You may be confusing +/- power supply rail fuses with left and right speaker fuses.

No, I am positive it is the speaker fuses. The power fuse is near the power switch.

After checking out all the supporting components. I replaced the STK amplifier chip and it works fine now.

I have the same problem. Where did you find the STK (power envelope chip)?
I also just picked up a TX-28 that's exhibiting pretty much the same problem.
djhack or Regena, where did you get your new chip from?
petraman7, the chip is a Sanyo STK4863.
If someone could get the STK number off the amp module, I can suggest where to get some.
Thanks
can this system be set for the knob to be turned left and right to go through the channels. the way it stand i have to click the top of the knob to get to channel which while driving can cause problems.
