CrownCRP14 Matsui 2096Child Lock removalConnect a tact switch between pin 4 & 17 of IC1 (in r/c) . When TV is sw on via R/C & a chan is selected that has a PASS code no. (child lock) will allow access approx 1 sec after pressing the tact switch once. The pass channel will clear & pic will return. To remove child lock permanently press tact switch again a message "PASS CLEAR" will appear on screen14-09-04
CROWNCTV-7296I have this tv model and at this moment it just has sound, not image. Could possibly be suffering from frame collapse, try turning up the screen voltage on the LOPT slightly and see if a white line appears across the screen, otherwise I would be looking to see if the tube heaters are lit.04-05-06
