Sony STR DE 197 Reciever with No Sound

The rear left and right channel has a audio output ic problem, first check rear speaker wires for shorts, if okay! the system will need to be assessed for repair costs.

try to check balance adjustment if working.

make sure the FM antenna is connected and in a good place then check to see if the A-B speaker selector is selected properly.check to see that the sound field is set properly, My 800 allows for several different options and if your speaker wires are reversed or not in the correct position front left at front left etc it will not send the signal to those speakers. try using the TEST TONE feature if you have one it will send a signal to each speaker in sequence (LF< C< RF<in order) it will go all the way around to see if they are connected properly, that way you can tell if they are connected at all or in the wrong spot on the back interface. I dont know if that is what you meant by AUTO CAL, but that is a seperate feature when you use the connected mic to determine range, height and distance to the position in the room you are most likely to be seated for optimal sound.

unplug,leet capacitors discharge, check back of unit where speaker wire clips are to make sure there are no wire strands touching each other,check same thing @ speakers, try turning unit back on.

still warranty period contact ur dealer ...............free of cost

Hi,

THe problem is with the variable resistor present behind your volume control knob, try replacing the volume controls variable resistor, this must work fine... this is a common prblem for all the music equipment that has knob control for the volume....

This resistor can be replaced with your product warranty, contact your seller for the details regarding warranty...No need to woory about this, this is a sommon problem for most of recievers

I have a problem with vintage reciever Sony STR-11L. Power transistors were replaced and I dont know what were original ones. Sound is no good and radiator is hot-I think problem is in replacement. Can anybody help me with?

go to your manual and repeat connection and setup and try with new cables because may be the cat bite something hidden from your eyes.

your RCA on your tv is acting like its in mono..it may be a problem with the jacks.  alternatively..you can buy a splitter and split teh side that sounds stronger (L) or (R) with a male to 2 female spliter out of the tv then back into l/r input on your reciever... It wont give you surround stereo...but it will soudn a whole lot better.

Power Amp IC gone in your set, replace it.
