A4000T CSMII hassle

[A4kT]

I've had a Phase5 CS MkII  overclocked to 60Mhz  in my A400T for about 5 years now  with no problems. This week I have confirmed that the A4000T "Audio/Visual" module is dying - condenser fell off - and have ordered a new one from SoftWare Hut.
THE CSMkII just won't boot up I get flashing green LED on the front of the A400T panel - no 'rainbow' startup screen. I have 4 x 32mb SIMMS on the board.
Tried reducing the system to it's absolute bare minimum and taking the CSMkII back to 50Mhz but no luck.
Tried each of tyhe 32mb SIMMS individually - no luck.
I've never had any probs with the Cyberstorm until now, none whatsoever - even after overclocking
My old '040 daughterboard boots OK but I get occasional  garbnage screens and have to re-boot.
Anyone think there is a connection between the dying A/V module and the non-starting CSMkII ? Even crazy guesses welcome. Bear in mind that the 040 and the CSMkII require the 'internal/external" jumper settings to be changed on the A400T motherboard - this may lead to a link to the bad A/V module - I just don't know.

(If the CSMkII is dead then it looks like I'll have to get an A1) :-?  :-?  :-?  :-?  :-?

Yes, boots  now with the 040 daughter card and the INT/EXT jumpers reset
I have a Retina BLTZ3 with the "Retina auto-switcher' and an external scandoubler in the Amiga vidoe output running CybergraphX V4
The setup has always been quite transparant (4 years) - If I run Perfect General the auto switcher snaps the video to the Amiga vid output - to the scan doubler and then to the monitor - no problems.
The A4000T's Audio-Video module has a dark, burnlike patch on it and the big blue condenser's pins were loose, one of them floating free - I replaced this condenser.

So far this is  list of suspects...
1.   CSMKII is dead (sob)
2.   All mem on CSMkII board corrupted (unlikely)
3.   CSMkII 50 & 60 Mhz oscillators both dead (unlikely)
4.   Relationship between sick A/V module & INT/EXT
      jumper settings (neccessary to run the CSMKII)
     
     I rate No.4 as being suspicious - with the 040 installed and the jumpers set to INT the system works as usual but graphics are 'fragile'.  With CSMKII installed an EXT jumpers set ... nothing.

what do you think ?

PS : Thanks for the swift reply
PPS : The CSMKII is not a DCE unit.

Thanks for a well thought out response,  you are obviously a genuine A4000T addict...
I still fret about the fact that my original '040 card boots AFTER the CPU source jumpers are set BACK to INTERNAL....
(there might be a huge difference btween INT-EXT operations)  ....
.....and that alone may be relevant to the CSMkII boot cycle.
Who can say that the CSMkII doesn't do some reference check for valid video video or whatever.
In any case, the big blus 'widget' on the A/V board turns out to be a condenser - not a capacitator - according to my local parts shop staff - they found the identical part.

In any case, thanks a lot for even replying - Japan - where I live - is a long way from even another A4000(T) to test the card in but I value your advice.

Your'e right I had the INT / EXT arse about in my previous post   but I did use the correct positions for the relevant cards.
The new A/V card should be here from Software Hut in a few days, I'll post my findings after I install it and the CSMkII and power up....

Thanks for the time you took to reply. :-(

The new A4000T audio/video module arrived today from Sofgtware Hut - installed it - set the MB jumpers J100 & J104 to INT -rre-installed the Cyberstorm MkII ...and ...
No joy.
Well at least I eliminated the (remote) possibility that the old A/V module was contributing to the CsMkII 's non starting.

At startup I get 3 or 4 LED blinks -which I gather is a ROM failure.

So... either my 060 itself is flakey or dead, previously couldn't overclock to 66Mhz - but 60Mhz was fine - significant ?

Or there is a short or burned out component on the CS.
Looks like a trip to France for this CSMkII

Or.. one of the suggestions from  responders to the original post...
 :-?

Well, I installed the new A/V module and ....... no luck the CsMkII still refuses to boot... the 040 card doles though.
I have sent the card off to Francwe to Jean-Jacques
(very friendly, helpful guy).
I'll post his findings in a week or so.

Just got an email from the wonderfully friendly & helpful ( & ovbiously talented) Jean - Jaques of www.amiga.fr
to tell me that my 060 Cyberstorm is now up and running again.
Took about two weeks all up including postal time.
I highly recommend his service to broken Phase 5 or DCE board owners.
I also support any legal action against DCE. Not returning boards is theft, plain and simple.

Sorry for the confusion about INT / EXT  ..  it was a typo error.
I always had both the CSMkII and the 040 daughter boards set to the correct jumper settings.

Got my Cyberstorm MkII 060 back yesterday!
Works like new. In fact I hadn't noticed but prior to the MkII's death, the 16mb of memory on the A4000T's motherboard had not been showing up. Now it does. I now see 146mb .
Strange but the A4000T now seems just as fast as when it had been overclocked to 60Mhz- maybe Jean Jacques of http://www.amiga.fr  did some tinkering
It is so nice to have a fast Amiga again- it really hits home when you go back to 040/25Mhz total 16mb of memory - comparatively speaking a once powerful and productive machine degrades almost to a games machine.
My sincere thanks and admiration for Jean Jacques. I can't recommend his service highly enough.
(Note ; He explicitly states that overclocking Cyberstorms is NOT a good idea)

The owners name is Jean-Jacques and is a really nice, garralouis guy - tell him the guy in Japan with the broken Cyberstorm sent you
( I'm NOT on commission)
I'd like to help him get more customers. As our classic Amigas get older a guy like him is invaluable.
