Hi there
I have a e-mac bought in Europe that works 220V and 175 Watts max. Now I live in USA and my computer is not dual. After buying an adapter to 110V and 250 Watts it worked perfectly for the first two months. Now the computeris still working but after some minutes on, the screen goes funny. It gets deformed and starts shaking. It seems that electricity doesnt run properly. I bought a back-up to avoid the electricity fluctuation but it didint work either. The screen still gets weird. I plugged the computer in diferent plugs and the computer worked less than an hour. Sometimes i cannot even turn the computer on.

It would be great if somebody who had a similar problem tell me what happent and what i could do to fix the problem.Thank you so much for your help.

If the computer is still working correctly (apart from having a distorted image), this probably indicates some sort of magnetic interference. Internally (in your mac), all components should be shielded against that, so I'd guess it is your power transformer that goes bad on you once it's reached a certain temperature level. just a wild guess though.

have you tried different locations for your mac, maybe there is some external interference? another power transformer? (maybe a stronger one?)

In case you have other displays available /(maybe from friends):
try plugging in an external display, possible CRT, and see what the image looks like there. and try an LCD, to see what the image looks like when magnetic interference should not play a role.

I would sell it and buy a U.S. eMac. The other thing to consider is the wattage rating of the converter: many of them only allow low wattages of non-resistive loads (things like hair dryers are resistive; computers and other electronics are not). You need to make sure you have a converter that allows higher non-resistive loads (you won't find an adapter like that at Radio Shack or a travel store, you'll have to use a real electronics shop).

And a faulty eMac would be worth what? Next to nothing..

As ambassadeur said, could be magnetic interference. Failing that, it also sounds a lot like a failing video cable(?) that many early eMacs were plagued with.
