I have an old VS-50703, it turn off after 3 second, I realize that the Diode D522 (the one in the PCB-main that rectify the -24V that powerup the convergence power amplifiers) was burned, I change it and the TV work for some 15 minutes and after burn the same diode again. CAn any body help me? |

maybe, I also was trying to set up the convergence, how to restart every thing to the factory default?
By the way, I'm using fast recovery diodes, I will try changing the capacitor |
