Toshiba 50V71 Chasis TAC 9958 Convergence Issues
Need help troubleshooting convergence issues on this set. Have
replaced both STK 392-110. Replacing the stk's seem to have not had any effect. I've checked all of the resistors near them and haven't found any open. I don't see any pico fuses to check. Is there any way I can rule out the digital convergence board? I could probably post a pic if this would help. Any ideas would be appreciated. Thanks in advance. Regards, Chance |

Check the +/- voltages to the STK Devices, either one missing indicates
either an open fuse device and/or power supply problem. A bit more deligence checking those particular circuits may resolve your problems. "b" wrote in message oups.com...
