My old (20 years) faithful Philips TV-set died last day, and I have tried to
find the cause, without success. As far as I know, I think it is in the startup circuits. What do I know? -Chassis: 26CS5779/13Z -Death: Just died while watching -Fuses: checked OK Symptoms: -No high tension. -Faint hiss in speaker -Responds to remote control but channel indicator dead. -13V and 190V test points on board have no voltage. -140V collector-emitter voltage on flyback transistor. No base voltage. Unsoldered and checked OK. -Most transistors tested by using diode test. 0.7v drop. =ok -Diodes checked OK. Any clues as where to look? thanks a bunch! Andy |
