i have a mac plus with screen problems, as i understand the problem is a cracked solder joint, but i was wondering if the solder joint is on the power/sweep or on the logic board
Got a tip for us?

Definitely the power/analog board, but it's likely the problem isn't so simple as that. That board was under-engineered in several ways, I replaced hundreds of them back in the day.
Yup, it sure was, I remember the mud-slinging!
But it won't hurt to try running a soldering iron over the LOPT, Yoke connector and Power/sweep to motherboard connector. the last one has a trick where the second last pin on one end is skipped - I saw a few where the last pin (after the skipped one) was missed.

yeah i took it to a tv repair shop and the guy replaced a voltage regulator witch sorted the problem for a month or so, then when it stopped working i assumed it was a cracked solder joint
can i get to the power/sweep board to solder the joints without removing it (i don't like the idea of scraping a screwdriver under the anode cap to discharge it)
Yes, just make sure it's been switched off for 20 minutes and unplugged from the mains. It's not "recommended" but for re-soldering the video connectors, you can get away with it.

it's been switched off for a year, so it should be fine, and i shall try soldering it after school
I should mention that there is a solder joint you may miss.
The motherboard/logic board connector has a pin that is skipped just before the last pin on one end. Make sure you don't miss the one after the skipped one. It's the multi-coloured cable, single row, in-line that is soldered horizontally and goes to the motherboard.
