Apple IIe Garbled Video

I recently picked up an Apple IIe. It boots on, and beeps like it normally should, but I get garbled video like in the image shown. There appears to not be any wrong (as far I can see) with the motherboard or traces. Is there a certain chip that would cause this?

The order of things to attemt

The order of things to attemt relacing for this, are:

 

RAM

CD ROM

EF ROM

 

I personally would suspect the EF ROM. There is a minor chance that it is the character generator, but with that kind of outut, I doubt it. 

Please also verify that you are connecting the composite port to an apropriate composite-in port, and that your signal frequency is correct (NTSC or PAL, depending on the //e system; you did not specify).

If the computer beeps, the

If the computer beeps, the CPU, RAM, and ROM are probably OK.

Looks like a video issue; possibly incompatibility with your LCD display. Do you have a TV or CRT monitor you can try?

 

Otherwise, there are numerous sites you can check to see which chips generate video and could be faulty.
