A2500 Flashing Video

[skwayb]

I just took my A2500 out of storage (already replaced the battery with a coin style years ago) and I am getting flashing video on the monitor when it shows the wrokbench screen. Not the entire screen flashing just parts of it. Like the icons and parts of the screen or going on and off.

Before I turned it on, I took the case off and noticed the A2091 board wasn't in the card slot. So I pushed it back in. Maybe the case was drop and a chip is loose. Any ideas of what to check/do to fix this?

If you are using the Amber / VGA Output, you may need to re-adjust the circuit using the pot on the back.

Check the output through the 23pin Video (15KHz) port is OK..

I didn't think the A2500 had an Amber chip (unless he's using an A2320 scandoubler)

@skwayb Any chance you can post photos of the symptoms? Might help diagnosis.

Sure thing I will get some photos and maybe record some video if I can. it is almost like a PC when you overclock the video card and get a ton of artifacts on the screen. So I am wordering if Agnus or somethign is partial popped out...
