The amplifier stage, which consist of power transistors, is experiencing an overload. Possibly due to the transistors breaking down or the DC threshold level is too high. The latter can be adjust when the input to the transistor is at quiescent or when no input is entering the transistors. I recommend having a professional make the adjustment.

because the audio amplifier IC´s are damaged and need to be replaced

These have a built in protection unit that senses heat. Capacitors are sensitive and will shut the unit off when there is a lot of heat or even if you turn the unit on more if it is too loud or the bass is turned up. It is a capacitor fault. Some of these units have a wire to the protection unit circuit you can unplug, but not sure where yours may be.

A record player has a very small signal coming out from the cartridge.If your amp doesn't have "phono in" then try "tape in".If no luck then you have to plug the record players output to a preamp first then from there to "aux in".

please refer the service manual if you have it....thank you

try RETREVO

check all the speakers connections for short circuits

unplug from wall
and
unplug all of the speakers and extra components and turn it on to see if the message disapears

if it does one by one start plugging that speakers back in
unplugging from the wall every time you add a speaker
(just in case the reciver only realises there is a problem after it shuts down)

if you find that after pluging in a speaker and when you turn it on check the wires for cuts or short circuits and check the speaker itself replace it with another and see what happens

need replaced power out ic and transistor....

Hi...
Some cable companies dont put the FM band on cable and some others put an FM trap (which kills the FM band) in line with the cable.
One of those is your problem.
You'll need to buy a FM antenna

Replace the IC 1101 with Part No. 6-806-144-01. This Ic will have updated software on board to fix the problem.

Hi,
This receiver has 2 modes for remote AV1 and AV2 that can be changed as per following procedure:

While depressing the [ENTER] button, press the [POWER] button to
turn on the main power. Either the message “C.MODE.AV 1” or “C.MODE.AV 2” appears for a moment and select the desired mode.

Hope this info will help you.
Thanks.

Hi, the manual for the vip622 (the model I have... not sure what you have) says to use the following codes for Sony Tuners / Amplifiers.

639 645 650 687 728 729 730
(located in the Appendix)

See Chapter 10 here:
http://www.dishnetwork.com/support/documents/receivers/vip622/default.aspx

for instructions on how to program the AUX setting on your remote and how to set your remote to adjust the receiver volume while controlling the Dish receiver.

channel is shorted. which means parts are needed.

This sounds like a very poor connection. Please make a new splice on speaker and receiver. This should take care of this for you.

here's the link to the manual in pdf form:

would go over the connections but depends on what you are connecting and there are 7 pages of connections in the manual.

Cheers!

disconnect all the speakers and turn it on. if it does not go into protect mode, then youve got a bad speaker or wire. good luck

Yes, it only supports an Active Subwoofer. That's what the Sub Pre-Out is for.

Your sub will take that input, possibly split to two RCA connectors, and its internal amplifier will do the rest. Its own manual will give the specifics.

Before you throw it in the garbage check all the speaker wires, if you have one strand of wire touching the case of the receiver that acts as a short to ground and will make it trip into protect intermittently.

First things first unplug all speaker wires and see if it turns off, if not reconnect them one by one until the unit goes off.

Hope this helps,

Thanks!

Radio will default to 2 channel stereo. You will need to use one of the soundfield processing modes to expand. Try using surround mode button to get to 6 channel or pro-logic.
