Not sure what the issue could be. The original problem is due to swelling capacitors, which is remedied by a new logic board (I have yet to have any repeat offenders after repair). Every connection within an eMac is either screwed down, clipped on or actually glue gunned into place, so aside from actually dropping the eMac, I don't see how they can come loose (I hope you're giving your eMac a smooth ride home in a soft car seat
). Will they let you sit down with the eMac itself in-shop to try it there?
Without seeing the issue myself I can only guess.....
You could be faced with two issues. One, it could be the CRT itself that is failing and therefore it will need to be replaced to fix the issue. Second, your eMac screen could be too close to a fluorescent light at home or main power cable within a work environment that causes interference and causes CRT monitors to do odd shaking/video issues.
