My receiver blows fuses F801 and F802 as soon as power is turned on. Been working on this for hours. All MP1620 and MP2488 check out fine. Diode 801 has no shorts. Only thing I'm thinking of is the output drivers upc2581v. I've read that they get really hot. I could not find the datasheet on them. Not sure how to test them. I do notice that the area on the board around the drivers are dark. Must have gotten very hot. If anyone could help, let me know where I could check next?
