Right speaker jack not working

Try interchanging the speakers. If the right channel works, you have a problem with your speaker.

Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

Right output transistor is fried, replace . Take old ones (both left and right) to radio shack for new replacements.Replace BOTH

check the ohms on the amp output and the amount of ohms on the back of your speakers they should be the same (or at least the amp should be more) ....your speakers may be overpowering your amp

some amps have a switch to bridge them rather than wiring a bridge meaning output is mono check to see if yours has this switch if you do simply put back to stereo

Hi...
Have you tried swapping speakers to see if the trouble moves to the other speaker?
It could be a dirty selector switch .

It could be a broken solder contact on the input or output RCA jacks

Hi,

Based on your post, the pre-amp is doing its job. What might be the mismatch would be the powered speaker system plugged into the output of the Rotel. Depending on what the "powered speaker system" is, it might be that it is a low impedance such as those used in computers whereas the Rotel requires high impedance to be connected to its output. What could be tried is to connect a regular amp or receiver to the Rotel.

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.

This sounds like there is a problem with the final output stage. Is this a new amp? Is it under warranty?

Sounds like wiring problems. Unhook everything, then get owners manual for proper instruction

Try only A speakers.
