Onkyo TX-28 Receiver Output Problem (by 2 users)

posted by djhack on Sep 02, 2007

Report abuse

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!

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)?

You may be confusing +/- power supply rail fuses with left and right speaker fuses.
