Acovea Posted September 16 Share Posted September 16 (edited) These components are black with like heatshrink tails coming off the top. TV2 in the lower left of the power board, but in this image the back panels are upside down so they would be in the upper right in this image next to those 2 big caps.

Imre Posted September 26 Share Posted September 26 Hi guys! I found this thread. I have an R-112SW that is dead now. I found a problem with the zener diode ZD4. Can anyone tell me what the voltage for this zener could be? Quote Link to comment Share on other sites More sharing options...

Currently, it is passing everything that is coming from the power supply (ca -55V). Edited October 17 by Imre Quote Link to comment Share on other sites More sharing options...
