SOURCE: No sound unless VIDEO signal is plugged into receiver

Connect the DVD player audio with digital coax into the digital audio connection as you described and the DVD video directly to the TV. Now switch the input mode on the receiver to DVD. Then switch the video output mode on the TV to correspond to the input you plugged into. Any source in 5.1 dolby digital or dts should now work properly and have picture too.

SOURCE: ''Power off ''flashes ten times after the receiver is turned on.

Most often it will require an output IC, but I have seen it be a bad ground or a transistor in the protect circuit.

Hi, Bennie.

I am going to take a try at helping you out with this today.

First, make sure that the DVD player works.

Attach it up to another tv, and make sure you get both audio and video.

If you do, then we go on to the next part.

If not, then the player has the problem.

Let's say that it works on the other tv, ok?

So, if that is the case, then it may be something as simple as having the input settings wrong on your receiver.

Sometimes, this can be from static discharge, other times bad cables.

Also, make sure that tape monitor 2 is not turned on, if it is you won't get anything out of your receiver unless the sound is run through the tape 2 jacks.

There also may be a burnt out fuse, or connection inside your old receiver that has gone and bit the dust.

After all, the receiver model you list was originally made in 1999, so it is well past life expectancy for it.

I know this may or may not be what you were wanting to know, but I tried.

I hope that it does help you in some way, and good luck.

An output transistor has shorted and is drawing too much current. It's fixable, but use a matched pair of output transistors instead of just changing the bad one.

Why is my RCA STAV-3860 not coming on?

It sounds like the unit is getting power but is going into standby mode due to an internal fault. Sadly, newer receivers these days are not designed to be repaired but replaced!

RCA Stav-3880 turn stereo on goes to full volumn

Take the batteries out of the remote control, then apply a piece of black tape over the IR sensor, Unplug the power, wait a few minutes, now power the unit back up, does the unit still have the same volume high symptom? If so, remove the tape and see if the unit responds to any other commands(other than volume) from the front panel. If it responds to the panel controls, the processor is most likely good. very seldom is the IR transistor bad, if it is no input command will work.

Use one of the screws that hold the receiver's case. Also, if you haven't already tried to use the turntable, make sure that the receiver's volume is turned way down, typically phono inputs are a lot more attenuated than aux inputs are. You may damage your speakers and or your ears!
