I have a magnavox 42mf521d/37 that turns on for about 3 seconds then shuts off again. When I got it I noticed there were 4 caps that were bulged. 3 were 1500 uf and 1 was a 2200 uf. So I changed the caps, and same issue. I thought this was going to be a quick repair like all the youtube videos, but of coarse not.The main filter cap has 165 volts on it and when you push the power button it jumps up to 390 for 3 seconds then back down to 165vdc. There is 24v and 17 going to the main board, the rest are 0. And 24v going to the driver boards.
