You wanna try changing the mode of sound. And for the volume, try contacting RCA to figure that out. Could be interfeiring remote signals. Also, you can post a question, just like this, on their support website. Click Here for that website.

All speakers work on sound level test but i have no music coming from rear, center and sub when playing 5.1 dvd. also i am unable to use any of the surrond sound modes. richard

What cable did you hook up your dvd? The 5.1 sound works only with optical cable or HDMI. Check in the input settings wich one is selected. With the analog cable ( Stereo RCA) is not working. Good luck!

RCA 3860 Audio/video receiver. Problem is that the volume knob doesn't change the volume, and if you touch it, it either gets too, too soft, or way too loud.

Sounds like dirty contacts on control itself. I would switch machine off from mains and spray the volume control with switch cleaner,YOU WILL NEED TO GET INSIDE THE MACHINE TO DO THIS. available from say cpc components preston. this should cure fault.

Speakers way too loud

You don't say how the Samsung routes out to the receiver. I assume you're using its RCA audio L and R jacks. Inability to adequately lower volume usually means you're NOT using a Line Level input, but maybe a speaker feed.

Your TV may have a setting for variable audio out, but even if you use the fixed setting you should be able to lower the playback volume to something comfortable with the receiver's volume knob. It does go down to completely OFF, right?

Speakers sound tinny

Did it ever work right? When did the problem start?


There are many DSP modes with this unit. Echoing voices is probably one of them. This is a user setting. Look at the front panel for information regarding that. I imagine the Straight/Effect button might change it.

Have you read the manual and followed the specific menus for setting up the DSP modes?

Screeching, Scratchy Sound: I don't think this is related.

Did it ever work right? When did this problem start?

Is it from all sources? All channels? All DSP modes?

I need more to information be helpful.

Mine does the exact same thing. If I pick up the front end of the unit and slam it down on a hard surface, it then displays HP out and sound comes out!! Freaking retarded. I wish I knew what was wrong with it! I asked RCA and of course they never responded. What a joke!

Echo when connecting Samsung Plasma to Onkyo TX-SR602

Make sure you have the tv volume turned right down as this will cause an echo,also set amp to prologic 2, and set up xover to suit your speakers or go for the THX standard of 80 hrtz and as a rule of thumb set front L,C,R speakers to zero rears to about +4or5 and your sub to -5[ dont know which speakers you have but try setting the subs on board volume to the 10,o,cloak position],also make sure the speakers -,+ are wired the same at the amp and speakers.

Hope this helps.
