Perhaps you could fix the 1/3 line problem at the same time (not that it bothers me really, but it makes sense to kill two birds with one stone) A artifact which I find more anoying is other flicker areas on the screen. my screen looks like this (out of perspective) **+++++ <1 (1/3 line flicker) **+++++ <1 ++++++++++++++++++++++++--------------------------------------xxx++ <2 --------------------------------------------------------------xxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 ......middle of screen removed.... -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 --------------------------------------------------------------xxx++ <2 ------------------------------------------------------------** <3 * = flickers a lot + = flickers some - = normal video, unused x = normal video, can't be used (WHY NOT!?!?)

Also ("you mean there's more?"), I have what I beleive is an actually defective 2320.

It sounds to me like something a capacitor isn't getting charged in time on the first try or something (...based on my limited hardware knowledge, I'm a "software type" :-). Any ideas?

The 1 and 3 stuff is very >annoying. Well, your're not alone. My A2320 is EXACTLY the same as you described above, and I know of two other A2320 owners who describe the same performance. If I may quote from page 1 of the A2320 manual: "The A2320 Display Enhancer board ... provides an alternate video display output that yields an image with no flicker or visible scan lines in interlaced or non-interlaced Amiga graphics modes." Well, my A2320 does not do this. If nothing else, that 1/3 line at the top contradicts this statement, but I, like Tyler, find the top right and bottom right 1/8 much more annoying. Scott: I believe a correction of these video artifacts should be a warranted fix/upgrade. The A2320 unit requires the upgrade to become what we agreed to buy and what we paid for.

Also, it sounds as if you are having a fine tuning adjustment problem that is manifested during power-up. Please follow the directions in your user's manual for this ajustment.
