Magnavox 30MW5405 trouble, Shuts off
I have a 4 year old Magnavox 30MW5404/17 Chassis L05U AA that suddenly turned itself off with no warning or prior problems. Turning it on gives no picture and only a few seconds of sound before shutting back off. The power light after "shut off" repeatedly blinks 3 short and 1 long. The usual click heard when turning on or off is quieter than usual. Took back off. When turned on, there is a faint buzz near the back of the CRT tube or from the horizontal PCB mounted there. Coming from the balance coil mounted on that board??
I saw many on this forum guided by Pee Wee who were able to find a bad resistor or cap and fix units with the same problem but on units older than mine. I can not find similarly described resistors on my unit. I did random testing of resistors and could not find any open ones. Can't find any bloated caps or signs of damage. Does anyone (Pee Wee?) have any ideas? I hate to toss a great TV bc/ of a potentially minor failure.
