Problem with Commodore 128

[Arjak]

I just found and bought a Commodore 128 in my own town, no eBay! Unfortunately, I'm having trouble with something.

 

I've found that while the system works in 80 column mode on the monitor I got with the computer, 40 column mode and Commodore 64 mode do not work. I've tried plugging in the computer to a different display, I've tried using a different A/V cord, but nothing works. When I try to use these modes, I get either a blank or glitchy display.

 

Please help me, guys!

Have the same problem. Was told it's the video chip for that mode.

Actually, it turns out the problem was me being a moron. I was browsing a Commodore forum for answers to my problem and someone with this problem was recommended to flip the RGB/Video switch on the monitor. I didn't even know there was one on the monitor! Sure enough, after a little feeling around, I found the button in question, and pressing it fixed the problem. Doh!

 

Give the monitor mode switch a try, gamezmaster!
