Question about Philips 27PT81S 27" TV
TV shuts itself off. TV will be on for an undertermined time and Red LED power light on front will flash then TV turns off. TV will turn back on either by remote or power button on set and the majority of the time will continue to shut itself off immediately after being turned on. If TV is left off for a long time TV will stay on for about an hour then start shutting itself off again. I have a feeling that it is a chip problem and needs replacing. The TV has been a good workhorse and in all other respects a worthwhile purchase.
Capacitor problems in power supply or a regulater isolate the power suppley by disconecting the line output stage/unplug scan coils for example and run a 60w bulb as a dummy load one wire to earth and the other to rail voltage colecter of line output transister if the bulb glows steady the power supplys fine
