SMPS Board Parts/RepairCE4000
Posted 10 June 2013 - 08:08 AM
Can anyone advise for the correct replacement part(s) for this board or, barring that, if there is a replacement SMPS board available?
I would prefer to try and fix the circuit myself, because I am sure an entire board is going to be an expensive component... advice and/or suggestion is appreciated.

The diode is high speed stuff. There is also some ajusteable precision diodes (such as U3, at 2.5V) that may have been taken out.
Hope this helps!

Unfortunately I am not the most electronically-inclined. I know how to muddle around a circuit board with a volt-meter, but I would have to D/L every spec sheet for every part on the dang thing. All of the rest of the parts appear undamaged - but the ones I mentioned above are definitely damaged.
Thank you for the suggestion(s). I will keep them in mind if step 1 repairs fail to rectify.

Even if you replaced those two parts, it still might not be enough to power up the amp. If the VIPer chip doesn't power up normally, it might just blow up again! Very touchy circuit. Beware!
Also, close to 170VDC is present at the VIPer chip. That's a lot of voltage if something goes wrong!

Note: I still have a lot of 4000 resources (some spare defective boards, hardware, etc), in Canada. In Canada you say? Pity! (from an old tea commercial)

He was super-helpful and seemed genuinely optimistic that they could isolate and solve the problem and get my amp up and runnng again. He said the CE4000 shares little in common with the 1000 and 2000 and is more like the K series, which sounded like a "good" thing in the way he presented it.
It's going to cost me a few bucks and a few weeks, but if he can rebuild/repair it for a couple of bills and I get 5 or 6 more years out of it... I'll be pretty ecstatic.

For what I paid for the amp over twelve years ago, considering what I've heard about these amps and their service lives, and comparing that to what it would cost me to get the cheapest comparable-power appliance (Behringer EP4000) if I can get five or sixe (or more) years out of this one with a component fix, then I will consider it money well spent.
