Re: My Lisa need help !

You've come to the right place to get help with your Lisa.

You don't need those batteries... they keep the clock running for a day or two when the Lisa is unplugged, then they are drained and eager to leak. Removing the batteries entirely is highly recommended.

The battery leakage usually corrodes some of the copper traces and so you should look for an open circuit or two in that area. That might address the beep problem.

More info:

The screen problem is probably not related to the I/O board/battery corrosion... it is typically a potentiometer on the video board that causes a video problem... see:

If that doesn't help, a description/photo of the screen would be useful for diagnosis.

Good luck!
