I have a similar ghosting effects, similar issue to
usualy down the middle of the screen like that.
and found a few things
- first, it was caused by loose connectors between the vga dvi adapters, once tightened screws they went away
- card was a bit loose, once pushed down abit, they went away.
- card connection a bit loose, i pulled the pins out abit on the socket to create a tighter connection, with a tooth pic
Now, however, these glitches seem to be difficult to get rid of..... they don't seem to go away that easily, with any of the above steps, but i found if I open the amiga and put my thumb across the solder line of the socket that sits on the lisa(?) chip, the glitches disappear completely, and i see a lovely stable image. (If I put my thumb on the double solder line of your socket, the row closest to say the amiga space bar, and in line with it, just above the lisa chip).
I am just wondering what you think the issue is? May i guess ... maybe I need a heatsink? or... please let me know of any ideas...
Only my thumb works, if I push down on the same point with a ball of bluetack and the same pressure nothing happens, the glitches artifacts or ghosting continues.
PS am I doing something risky? by touching it?
PPS I am using 2 psus, one a micronik infinity tower psu, and one a replacement one from electroware (link removed) It seems worse with the c64 one.
