work is now complete,monitor is working perfectly fine.this can be picked up any time after we organise it

Edit: not much to say,pictures are to show it works.i didnt take any as i went along it didnt have any serious fault worth noting

 

[Bryanpoprobson]

Elite and Redstorm Rising here I come..

 

[roy_bates]

couple more pictures,to show the rgbi works,just incase it becomes a concern later on,obviously im using a pattern generator

 

[Bryanpoprobson]

All working fine, did have a slight flicker at first, but when I screwed in the connector that stopped, the video is the title of blood money, the sound out of the Monitor is quite good and bassy. Thanks again for the work Roy. File was too big..

 

[roy_bates]

it was a pleasure,enjoy

I have a small problem (I don't think its the monitor) but playing for 30 minutes and I lose the picture. Both the Amiga and the Monitor lights are stable. Turning the monitor off has no effect, but rebooting the Amiga brings it back. Any ideas what to check?

 

[roy_bates]

not sure, i cant tell from that,obviously something to do with the amiga,if it crashed normally dont they put up a guru message?

 

[Bryanpoprobson]

That's what I thought, makes me think it not crashing but could be an output fail.. The first time it happened it left a pixelated screen now it goes black.

 

[roy_bates]

maybe it has chip creep,if it was the 500 you were talking about,that would be possible,plus it seems take time to happen like a warm up

 

[Bryanpoprobson]

I did soak test it when I rebuilt it, but using a borrowed modem so I never really tested the monitor out.

 

[roy_bates]

sorry,i dont know what any of that meant,not sure if you put a typo?

I gave it a long duration test when I rebuilt the Amiga to test it’s stability (soak test) but using a modem not the monitor output.

a modem?

 

[Bryanpoprobson]

Sorry that’s the BT in me an A520 Commodore Amiga Video Modulator Composite/RF Video Out. Anything like that I refer to as a modem.

 

[roy_bates]

ah right,that was a massive head scratcher there for a moment,litrally sat here wondering why a modem would be useful for this,considering what a modem does

Edit: i have an idea,maybe try a different game/software see if it takes the same amount of time,your basicly looking for consistancy in the fault,see if it does it during disk access things like that,or does it in the same place in software or its random,its hard to diagnose what i would consider a intermediate fault
especially one that take aroudn 30 minutes to develope to the point it black screens
