Socket installed, I tried the old denise in it to make sure it still behaved the same, it does. New denise is a big improvement but still not all good. The picture now appears kinda properly and the mouse works again so the overheating denise must be dead or severely wounded.
RGB and composite have some vertical bars like I showed above but not stable, move the mouse and the bars change. also some shuddering/flickering of the whole picture. I'll try to post a video later. No picture on RF?
@cpiac64, I think you might be right about agnus. I'll try the one you sent and see if the fault changes to what you had. Need to get a socket for it first.
PS. Soldering experts, I'm pretty new to hot air desoldering, How long at at what temp would you expect to remove a 52 pin plcc. I used the correct nozzle but it seemed to take a very long time to melt the solder. The time it was taking made me nervous and I managed to damage one pad when it finally let go.
