Re: Westinghouse DWM50F3G1
Caps EC20 and 21 are both 100uf 100v. I found these Q15, IC3, startup/running caps EC2, EC3. and the rectifier, but not sure how to check those with a meter. About the only thing I am good at with a meter is checking voltage and continuity. I did try heating it. EC5 I did have voltage there when I checked before but after I put a little heat in that area I have nothing and also now the voltages on the LED output are all over the place. Anywhere from 25v all the way to almost 200v. It was not doing that before that I noticed anyway , but I was not holding the probe on there very long either. I too notice that I have a hum or buzz coming from 1 of the 2 transformers? between the 2 heatsinks. At blk/on I am getting close to 4v. As far as knowing if they are known good no. I bought these all in bulk and they where all suppose to have cracked panels, but I now know that is not the case because I have got at least 10 working sets.
