A4000T not giving video output from my Cybervision64 Card

[Vlabguy1]

I need tons of help!!  I have an Amiga4000T with a Cybervision64
graphics card, whicho does not seem to work.  The basic video
output works..ie a 1084 plugged into the video port works.
I tested all the Zorro3 slots, show config shows card as working..and I also
tried another Cybervsion64 card..Any thoughts on this from anyone!!  I did
notice a missing 12v from one of my PS outputs was dead ..Does this help?

Thanks everyone

Yes I should have been more clear.  I have Cybergraphics4 installed.

[Vlabguy1]

Gee thanks, but no thanks!

Thanks.  Ok..let me say this..the card+Tower have been working fine..I messed
up on the software end..not sure now what I did but I totally messed it up..
So I decided on a fresh install of OS3.1+cybergraphXv.4 I did not however use
the orig. cybergraphx disk(which I have btw).  Also, upon boot up to the
NTSC(1084monitor) which is fine.  When I go to switch to a cybergraphx screen mode..it seems to switch but I get nothing on monitor thats hooked up to the
CG64 card.  Maybe your right in that I have to have installed the orig. CG disk then upgrade to the latest version cybergraphx..sounds strange but is this possible?

patrik,

I actually checked both ports..with same result..ie nothing on the screen.
Yes the card worked just fine til I started messing the OS..I think I mixed
some files from 3.9 and 3.1..But have since reformatted and installed just
3.1 which works just fine with a 1084 on the 4000T(ie. not useing the
paasthrough option on the CV64)..I hope it is not the mother board..could
that be possible.  Although the show config shows card is working, but
Im not sure how "smart" the show config is, ifyou know what I mean.

Thanks
Rich

Patrik,

Tried that..fresh install and select CV64 screen..and the computer seems to do the switch ie the 1084 turns off..but then nothing on the CV64 monitor..and Ive tried several known working monitors..mmmm..Im confused .could it be my motherboard, the video module for the 4000T???

Thanks alot everyone who is trying to solve this with me :-)..
Peace

Patrik,

Yes the cybergrahpx Vs. the AGA video output does makes sense.  Riddle me this if all else could the motherboard be at fault here, which is my worst fear!


At the moment Im not at my computer :-(..
the monitor is a Viewsonic 19" not sure which model but I will find out..I also
been useing an Idek 17" you know the one they used to sell just for the Amgia
way back when..
Resolution is 1024x768..nothing too crazy and with out being at my Amiga not sure the frequencies..

I have full confidence that we/I will get this up and running again..but has anyone run into a similar problem and the fault being the Motherboard???


Again thanks for everyone helping out with this!!!Just to let everyone know that I have been an Amiga fan since before they were released and a proud owner since 1988..

If you could please post your results..
Thanks

Thanks for the reply.  Im actually running OS3.1  The Cybergraphx software intalls fine and Im able to select screen modes from the prefs. but when I
select a CV mode the computer does the switch but with out any output to
my know working monitor.  

I ask again could this be a Motherboard problem???

Thanks again
Rich

Thanks for the PS at the end of your post!! I will keep that in mind and now
not lose any sleep over this one.  Im going to try a Retina Z3, then
a PicassoIV..then trying to think of some other boards I have that I could
test.  I prob wont get back to til this Sat.  
But Im still confused as to how I have bad software..which is could be
bad my OS 3.1 or the Cybergrapx??

Thanks again for all your intput.

Thanks for the response.  Even though I have done several installs I will keep
trying.  My worst fear is that the motherboard is toasted, which would not be
good :-(..And I dont even know how that would be possible.  I will post any
and all results for sure.  If anyone has/had  a similar prob. let me know what
happened with that..please!
Thanks again
Rich

Just one more thing..I tested all the ports and I have a voltage loss on the serial port???  Could this be a failing PowerSupply and could this effect my
Screen mode switching??

I know its a long shot, but I figured I would ask

[Vlabguy1]

Patrik,

Could just the video output part of the mother board be fried??  I didnt mean to imply that reinstalling OS would have fried the motherboard..Sometimes these things just burnout.  It is an old machine, although with very low hours.  
The 060 card that is in the machine is a QuickPak(I believe)board.  Which has
been running just great!!!
The more I learn you all of you Im beginning to think its a software thing.  
Well, speaking of odd things..could a incorrect OS install cause this problem?
Has anyone run into similar probs with the video output to a graphics card?
Im hoping it just a syncing problem and nothing permanent.

Thanks again Patrik!!

Long live AMIGA!

patrik,

1. Makes me feel much better now that it might not be the motherboard. Thx.

2. The 060 files are in the correct place, but perhaps not..I will check double
     check then tripple check.
     I will check to make sure the 060 disk that came with the card is all OK.
     Thx..I didnt even think of that
3.  I will double check that as well..but I believe the monitor stayed in
     powersave mode.


Thanks again for everyones input and keep it coming!  Solving this hopfully
minor problem can save someone else a headache later on down the line.
I will post further info and any and all results.

Thanks again
Rich

[Vlabguy1]

Yes please share how you did it??

thanks
Rich

@yogisumo..

No worries ..I will post all my results..tomorrow when I solve this prob. of mine.
I will be working on for as long as it take this weekend..and I hope that by the
afternoon I should know more and have it fixed, yeah boyee..unless ofcourse
it turns out to be my motherboard.in which case I will be one BUMMED out man.

Take care everyone!!
