Hello!
Looks like quite the knowledge and community in the forums. Anyway, I'm the newly gifted (unexpectedly) owner of a 2467B with a few issues (some stuff just missing such as the HV shield and rear plastic cover, plus a couple face buttons), however everything else in the unit has been untouched electrically near as I can see. My guess being the previous owner (who died unexpectedly) probably got in over his head upon opening it up, lost the parts and now here it is in my hands now. Anyways...
Upon, plugging in and attempting to power up, the furthest I've gotten is hearing a ticking from the SMPS, and a flashing Trig'd LED. Nothing else so far (no screen display, no further boot sequence that I read these things are supposed to do in terms of the self-test and diagnostic routines that it would normally do and as they explain in the service manual). I did discover that the illumination for the display will pulse as well after messing with that control a little, but that's the only other lighted thing I'm seeing. Voltage readings from the J119 socket are all consistently low by around 2-3 volts, and appear to be cycling up/down slightly on my DMM- point being they are not staying stable. Upon digging out the power supply (not awesome to remove it I will say haha) I see all the electrolytic caps are original to it, none look physically damaged or bloated. The "across the line" caps are all cracked looking on the clear plastic but that's about it there. No scorch marks, burnt up traces/diodes/resistors, etc. Fearing damage could be done to the SMPS (I'm kinda new to this, and this is BY FAR the most complex thing I've tried to fix on my own), I briefly powered the SMPS on the bench no load for maybe 3 seconds. No high-freq whine or ticking noise whatsoever came from it. I turned it off after that; I'd read one could fry the FETs doing that (dunno if that's true but it sketched me out so I did that quickly and turned it off). Anyhow, re-attaching it to the rest of the scope gave same initial power up result. I took up most other suggestions I've read that the caps in there are long past their life and were prone to trouble and ordered as low of ESR replacement caps as I could find via Mouser and thus far I'm in it 25 bucks now which...I can live with that just seeing what's up (they should arrive this coming Wednesday). Depending on what happens after this, I know I'll need help either way if it works or not. Any thoughts, tips, suggestions are most welcome. As I say, I'm fairly new to stuff quite this complicated. My prior success was with fixing an HP 6236B power supply as far as test gear goes. Most of my knowlege is in audio (guitar amps, some hifi, modular sythesizers, etc.) so this one I know is going to be quite a steep mountain to tackle. Again, thanks to all who are willing to give me some guidance on this one.
