Hi, would anyone be able to help?

I've just bought a second hand Barco 708MM it's ace, has the Iris3 and Lido installed. Brilliant, except I've just powered it on and it went pop.

I've checked the fuses and replaced the standby and one of the HV 3.15a.

It blew the standby power fuse again when I switched back on. The HV one is still ok. I noticed a jumper (J20) that disables the standby psu. doing this brings the thing back to life, except it only projects very dim and a small line appears at the bottom that moves across the screen.

If I remove the jumper from the standby psu, it is completly dead no lights or anything, if i remove the jumper it powers back up, as stated above.

I've checked the small dc fuses and they all seem ok.

Their is a transistor I think q10 that has a slight burn next to it, could it be that?

I feel sick that I've not seen this thing work.

Am I right in thinking this is the SMPS? Would anyone have one of these for sale? I live in the UK.

cheers guys for any advice on this.

kind regards

Oli.

THe standby supply is bad or so it seems. I have spares if you want to buy one. $75 plus shipping.

BTW, that is not a 1.25 amp, it’s a 0.125 amp fuse which is hard to find. If you put in a 1.25 amp, you probably have blown more parts than originally were blown. I’d buy a tested working replacement rather than trying to repair yours.
