More on Sony KV-1380R with shrinking picture
Just saw the picture shrink and the HV drop from 25KV down to 20KV.
Found what appears to be the regulator, which appears to have already been replaced and will have to find the output terminal and watch what it does when the trouble reappears. Did find out that just clicking the power button off and then back on, within 10 seconds or so, the picture returned to normal and the HV went back up to 25 KV. More detective work to do. Regulator has markings STR 30135 6NO1. Five terminals, only 3 have connections, other two terminals may be for conducting heat out of the unit. |
