hello everyone,
ok, same problem as everyone. only mine was a bit more severe, as in, the regulator fried. so i got replacements off ebay, had a good read of the problem, worked out what to do and replaced the three capacitors, C807, C814 and C850. then replaced the burnt out regulator (U801). coundn't work out the number on that one because it was fried from the top (i understand the original number is AZ1021), but the replaced one was numbered Z1021HAI with the number ZA1023 underneath it.
but now the problem seems to be the PSU, or at least it seemed at first. checked voltage output at the white connector to the motherboard and had no reading whatsoever. no 5v no 3v or no 12v. the hhd connector showed a little voltage but nothing what it should be. so replaced PSU with another one from my other working box (both Vu+ Duo), and had the same result. no output at the connector. how can that be? i put the first PSU (from the fried regulator box) into my other working box and it is working fine. the box is working as i am writing this post.
can some expert suggest what might be the problem, and tell me what to check next? everyone else says that replacing the capacitors and/or the regulators gets the box working again. but obviously not in my case.
thanks in advance and apologies for the very long post.
