Why is my Mac 128k behaving this way?

[macpokerstars]

Hi,

I have a Mac 128k and it's makes weird noises. And every time it makes that noise, the screen shakes and shrinks.

I have posted a video on youtube:

You should put the video in full screen because it's small.
Listen closely to the sounds and look at the edge of the screen; it slightly shrinks every time.

Then when I start a program like notepad, it crashes and eventually gives me the "bomb alert" and prompts me to restart.

What is wrong?

Note: it's an 110V version, and I had plugged it into 220V and messed the power circuit. I had it repaired though, so on theory it shouldn't have any incidence, right?

Thanks a lot for your help

Regards

Looks like it's on its way out.

Sounds like an analog/power board issue. When you run programs it requires more energy and the power board is struggling to provide enough current. Thus it's like a voltage drop and the screen begins to shake.

Could be that it needs a voltage adjustment. If you've not taken the back off yourself before, you may not find it too easy.

Hi everyone,
thanks a lot for your responses.

@MacTech68: is this something that I can fix by myself, by opening up the Mac? Or do you think a pro should take care of it?

Thanks again

Experience tells me that if you're asking, you're better off getting somebody else to handle it for you.

If you have to ask, don't try it yourself.

Apple can't help you out with this issue, try to find a PC shop with some older employees, they might be able to help you out.
