Amiga & the Gateway KX2153 21" LCD Monitor

The vertical lines are probably an artifact of the adapter, I had one of those C= 15 pin adapters and had the same in 31khz modes.  You can fix it by (iirc) soldering a resistor between two pins inside, I think there is a doc on Aminet.

Hth.

Yep those are the same instructions I followed years ago, I remember the mention of the genlock.  Good luck!

Great! So I assume it worked out okay for you? Any chance you can post a photo of your work? I have an idea of what I am going to do but it would be good to see what a completed fix looks like.  

I'm afraid not, I don't have the adaptor anymore.  It did work though, the lines were gone completely.

OK, that was a bust. So, I took the resistor off and checked for continuity from pin 15 to ANYWHERE on the board and it goes NOWHERE! :confused: Check your adapter for yourself! And Me! :angry: Plus, that diagram that AmiWest posted shows NO pin 15.

Sorry to hear it didnt work for you, I found my original post on comp.sys.amiga.hardware when I did the hack on my adaptor and I said it didn't happen in NTSC/PAL modes which yours clearly does if it happens on the insert disk screen.

Here's the old post in case it's helpful:
