Own PT-50LC13 since 12/03. As of today set comes on normally and plays for about 3 to 5 minutes and then turns off. The POWER indicator flashes red and does not stop flashing even after a LONG time. The red LAMP indicator flashes every 6 or 7 seconds or so. I removed the lamp and it looks OK. I know the fan is running because I can hear and see it. I am baffled as to why the set would look normal when on , but then shut down with a LAMP warning. I can repeat this over an over.
Hopefully someone here can tell me what is wrong. Thanks a million!
