I just had one die in a 2 bcr2000 carry 'round flight case.I thought "Oh no I re-capped that one - what now!?Thanks for the cross-ref data foot work for us. I'' try that is it's not the caps again. I used 6.5v caps cause that's what I had. - I'll get my coat.

Subject: [bc2000] BCF power supply repair success story
New member here.I've just done a successful repair on my BCF power supply.The main switch mode chip TNY268P had failed, got a replacement (actually a TNY268PN) on eBay for £2.30 (UK price), soldered it in, success! I'd already checked the capacitors, but they were all OK. This is a fairly simple repair if you have soldering experience or you could get a tech to do it for you. Be very careful of the high voltages on the PSU board when testing!The PSU 7 pin connector should have the following voltages on it: 3 pins at 0v, 3 pins at 5.4v, 1 pin at 4.9v (the one with the red wire).Hope this helps someone fix theirs. I don't have the schematic, but it's a mixture of the TNY268 data sheet and the TL431 data sheet, both available online, as are a couple of guides to opening the unit up and dismantling it.Good luck!
