Indivision ECS Issues

[barney]

Hello everybody I have a question for you about the Indivision ECS Scandoubler.  After a few minutes of usage on all my monitors, the screen becomes files with horizontal lines and severe bizarre distortion.  Any idea's what this is?  It's rather annoying and makes me really miss my old A2320 I sold a while back.

I own three of them and never had this issue.  Do you have the grounding wire securely attached?  Flashed to the latest 1.10 firmware?  Everything firmly installed and pressed down in it's sockets?  Connections all nice & tight?  Tried with a different monitor cable?  Confirmed that your monitor works fine?

Typically when you see problems like this start occurring as the device warms up, it's a heat issue.  Have you tried with the case removed?  Do you have anything else installed around the board that might be blocking airflow?  Press down on the top with your finger, does it feel very hot?  Blow a fan on it - does that increase the time period before when you start having glitches?  Try with a different screenmode - i.e., 800x600 is more taxing to the hardware than 320x200.

Sorry, a lot of options to try, but am sure the problem lies somewhere in there!

Thanks for the tips.  I have a feeling your right on it being a heat issue.  I will sit and watch the screen and after 10 minutes, the problem occurs.  Rather than being a scandoubler issue, I have a funny feeling the problem the Motherboard starting to get flakey.  I guess I'm going to have to open it up and take a look.

Which model of amiga are you using this in?

I have 3 Indivision ECS (and 1 AGA MK2).  I find that Indivison needs really clean power.  This was particularly an issue with my A500+.  The screen would tear and distort especially if you use the floppy drive (the floppy added noise to both 5 V and 12 V lines).  I switched from an A500 Obese Boy (sorry not a politically correct name)  to one of my XT power supplies modded for an A500.  Now everything works great.

My indivision AGA mk2 had the same artefacting due to heat, Lisa went insanely hot and within minutes everything went haywire, a good polygon based game to stresstest with was 4D sports driving (aka stunts) running that in whdload kicked me to workbench with unrelated error codes quick when cooling was insufficient

So as others have said try just to run the miggy case open and maybe some kind of fan moving some air, mine needed a fan directly on the indivision/Lisa to function.

 This is how I fixed it:

yeah I'll +1 that heat check, and power's not a bad shout either.

i'm a paranoid to run hi-res/scandoubled screenmodes on the IndieAGA given Lisa's propensity to heat up.

in the A500/A600's I've not had any problems to that degree, but it does sound like a data corruption issue. either flackey data getting to the IndieECS or denise getting toasty.
I do notice a scan line ... thing...  on higher res modes with the Indie. and I think its down to denise not able to shift data fast enough rather than anything wrong with the indie.

My Bvision3D card taught me to check everything, as I was getting artifacts until I put a heat sink on the PCI adapter chip! and found that by an accidental touch and nearly burning myself.

hope you find a solution!

That is my problem exactly.  the screen will tear and distort.  I bet it is the power supply.  Is there a place out there that sells new XT modded power supplies? Thanks.

I'm using an Amiga 2000.  That is my problem exactly.  the screen will tear and distort.  I bet it is the power supply.  I am going to check out amigakit and get an ATX power supply adapter and replace the power supply.  Before that I might even get a good heatsink/fan and see if that fixes the problem.

Mine seems different.
Only one time while playing a game did the display just cut out with no signal.
Came back after about 10 minutes.

Now I have notice some interference in a few lines of display, not a lot, that happen at start up. Went away after awhile.

Also went away went I changed screen modes from 1024 by 768 down to Pal hires interlaced.

Also went away went I changed screen modes from 1024 by 768 down to Pay hires interlaced.

This is typical.  1024x768 is much more taxing on the hardware than 640x512.  Add additional cooling.

The interesting thing is that I used my INdivision for about 3 years before this problem started.  This leads me to believe it's probably is in fact a failing item; possible the power supply.
