Sorry, no freebies from what I see online. But, when you power up, does it play before it shuts down? This will help me formulate a better answer for you...accordianman

Select an input that is not connected, for example select CD with no cables going to the CD input on the backside. Will you then hear equal humming on both channels? If so, the amp stage is ok,
and the problem lies in the signal level circuitry.
Open the cover and use a plastic (insulated) stick to touch suspectible cables and components. When the sound returns, you've found the cause. Resolder or reseat the component/cable/card.
Use the insulated stick, NOT your fingers!

Hi,

Since it was just recently installed, would it be safe to assume that it is fairly new? If yes, perhaps your best bet would be to return to dealer/manufacturer for repairs/replacement. It is highly probable that the unit has sustained major hardware fault at least on the right channel. Even if it were just a fuse, it would still be to your advantage going that route.

Should for some reason you would venture a DIY, diagnosis and repairs of course would require fair familiarity with electronic components and circuitry, use of a VM and a soldering iron and preferable access to a service manual or at the very least a schematic diagram with voltage readings.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
