I have a Philips Magnavox TS2744 C123, chassis 27B800-7562. When I turn it on the green LED comes on and then the TV immediately shuts off. I don't see any damaged components on the main board or the CRT board. It appears there is a current overload that triggers a safety shutoff, but where? Perhaps a voltage regulator or rectifier is shorted? Any ideas?
Philips TV power problem
vmac: You are very correct in your assumption.... something is shorted.... could be any where... the power supply regulation circuitry, HOT, flyback, flyback derived B+ loads, HDr, VDefl, etc, etc. The fact that you "don't see any damaged components on the main board or CRT board" is obviously a nonsensical and unreasonable statement..... as we all know, parts that "look" OK can easily be defective.... they must be properly tested with appropriate test equipment and test proceedures. Dust off your DMM and start performing some basic technical troubleshooting, meter readings and component tests. You may want to go to the website for this newsgroup at
