i have heard that transformers never go bad, but i am working on my 720 degrees game right now and all i can think is that the +12 volts that is supposed to get to the audio board is not working? i get no audio, no picture, and the video and cpu boards show the proper +5 measurements.
is there an easy/safe way to measure the voltages coming off the transformer so i know its getting power and working? i know the 2 wires coming off that go directly to the monitor are giving power, but not sure about the 3 (red, orange, violet) going to the fuses then to the audio pcb...and there is the red/white common wire as well coming off...all the fuses show continuity and are the correct type of fuse.
any ideas?
if this is a transformer issue, is there an easy replacement or fix?
thanks
