Mitsubishi TV CS-3506 What is proper B+ voltage ? alt. ref: CS-3506R CS3506 CS 3506 CS3506R CS 3506R
Hello,
I just fixed this Mitsu CS-3506 in a trade deal with a friend of mine. Crikey after replacing every Nichicon black cap with a " + " stamped into the top of the can and also hours of reworking electrolyte damaged traces I think I'm about ready to make the drive and put the chassi back into the set. Before I pulled the chassi out, I measured B+ to the HV section to be 149 V None of the Mitsu schematics I have for other sets indicate any B+ this high. Could this be normal for this model, or should I take a closer look at the SMPS regulation before I reinstall the chassi and fire this puppy up? Thanks, Dave Moore |

Sorry for the double post. My news server wasn't posting so I made a Google account for the screen name "DSP" and posted only to find to my extreme dismay that now ( special thanks to Google Groups), my email address has been posted.
