Question about Philips Magnavox 51MP392H Rear Projection Television
When I push the power button the light flashes, the TV Chirps and goes off, It then repeats this over and over until the power cord is unplugged. I need to know what parts to buy to make this repair , where I can buy them and if they are plug in parts or if they will have to be soldered to one of the boards. Thanks Bassnut_22
This sounds like a power supply problem. 9 times out of 10 you are dealing with soldered components. Now for the bad news, you are not going to solve this problem by just getting the parts that you need as easy as you think, any number of things can be wrong with tis TV. First I would check the Horizontal Output Transistor to see if it is shorted to ground (check the collector in reference to ground), also I would advise checking the Integrated High Voltage Transformer (voltage output test, resistance test, capacitance test and ring test). The tests of the IHVT will tell you if the transformer is bad and in need of replacement. These are the first checks you will need to do.
I hope this Helps,
