After pulling my Apple IIGS out of the attic, I plugged it in to my modern LCD TV via composite. However, upon boot up, the screen is garbled and jumpy. If i wiggle/twist the RCA connector at the IIGS end, i can fix the garbled video and jumpiness, however the colors are all wrong, as in they look very deadened/muted. Medium blue appears as a dark blueish grey, dark red looks like brown, yellow looks very faded, etc. Is this caused by the failure of a certain chip, should I replace the capacitors, or what?
EDIT: I should also add that if I flip the switch on the back, and turn it on again, I have to wiggle the RCA cable all over again for a while to get the image to work.
When viewing text, there are also several pink/green artifacts. Knowing that it is an Apple II on a color display, this could happen, but I just wanted to put it in here to be safe.
