What sound is my SE/30 making??
Posted by: Slammbone1986 on 2022-11-24 21:24:57
Had this baby a long long time and finally decided to recap the entire machine. Console sent me the goods and I recapped it without a hitch. Went to turn it on and that god awful noise you hear was coming out of what looks and sounds like the flyback. But I don’t know what I could have done has anyone had experience with this sound?? Oh and it was working perfectly fine before I recapped it. Any help to figure this out would be much appreciated!
Thanks
Tyler

Possibly a loose connection or weak solder joint - did you reflow any of the solder joints when it was recapped?

Yes I always do anytime I have one apart even if they aren’t cracked. They will all eventually turn bad. I think I’m just going to have to go over everything. Do y ok think it’s something to do with the analog board or the logic board?

Analog board I think. Definitely worth going over your work again especially if it was OK before the recap.

Yeah so I forgot to mention. I took the Logic board and put it in a known good machine and the same thing happens. So it has to be on the logic board. Earlier I found a bad solder joint on one of the axial caps, on the video connector line, but of course it didn’t repair it.

I’ll keep looking this evening for any kind of breaks in traces or bad cap soldering. Will report back later.

Had a couple of bad solder joints on the caps and one broken trace. Works like a dream. Thanks!!
