For CD playing, can you swap the front R/L chnl. to the rear R/L chnl?

Okay, my Sony ES receiver is 16 yr. old. But I only use it for 30 min. every 2 days on listening CD music, currently connects to 2 speakers. Every so often, it gives a high pitch static sound, someone told me this is due to the front R/L channel contact has wear out

Now, the rear channel were hardly used, what if I swap the 2 speaker to the rear Right/Left channel?

As it should be 100W/channel.

I would think it would automatically play 2 channel music through the 2 front channels. I can't think of a way to make it use the amps in the rear channels as the fronts.

how about spraying a little contact cleaner in there?

You can't make the surround R/L your front channels.

The problem is, in where? The contact is the fiber optic connecting from the output of the DVD player to the Optic In of the Receiver

The 2nd connection is the Speaker B of Front Channel to the speaker.

The static, high pitch sound seems to be caused by the unit can't detect the connection is currently at the DVD player. So it play a high pitch sound as the volume is up

Check the Owner's manual and see if there is a way to reset the Sony ES. At a minimum the FL/FR speakers must be connected (so no you can't swap to SL/SR), although if there are separate Front B connections, you could try those instead. If the issue only presents with the CD player, then you may want to replace the CD player.
