Replacement video card

Post by OldFoo »

Hey All,



This is about a Let's Go Jungle!: Lost on the Island of Spice arcade. From the beginning some bad graphic artifacts existed with the original GeForce 7800 video card. The situation gradually got worse. Finally, I purchased the same GeForce 7800 card, cleaned the whole Lindbergh unit up and replaced the cooling fan. The new fan doesn't have an RPM detection, though.



Now, the arcade doesn't boot with the new video card.



When I put back the old one it works, a bit better than before, with the same old artifacts.



My question is: Is there some kind of protection, which checks the graphics card serial number or is it the problem in the new fan. I am lost, so I would greatly appreciate any help. Thanks.

I am having the EXACT same problem with my Afterburner Climax arcade, that also has a 7800GS. I did not change the fan. The unit is in its original condition.



I did notice that things improved after cleaning the original videocard thoroughly.



Next step for me is to improve airflow in the cab which.. well.. sucks :-) The PSU is right next to the Lindbergh, taking in hot air from it. The exhaust fan in the rear of the cab actually blows air around in the cab itself, due to the fact that there is no decent exhaust opening (it tries to blow air through small openings). POORLY designed, IMHO..



I also got a Zalman VF700Cu cooler that I might try.



Another step: I have multiple 7800GS cards coming my way the next few days/weeks; I will keep you posted on my progress with installing these.



If money is not an issue, we can always buy a working card from SegaShed, but they are not cheap (for a good reason, apparantly :-))



I am actually glad that I am not the only one facing these issues with the Lindbergh.. Sure hope we can find a solution.

Take a look at this: http://www.youtube.com/watch?v=A5ePydQ2XpY



Filmed while playing; artifacts are showing. Especially at 1:30 (the tree on the right goes awry).

I am guessing the original graphics card uses a different/custom? firmware. Does the original graphics card work in a normal pc?.

So.. I did a very thorough cleaning of the entire Lindbergh PCB. I even removed the CPU cooler to give it a good cleaning. A lot of dust had accumulated beneath the cooler as well, making it hard to reach without removing it.



A small anecdote:



I always build my own PC, so I thought this would be a walk in the park.. If only it was..

So off I went, carefully took the cooler, wiggled it a bit, and 'pop!': I had it in my hands, but only to find that the CPU was actually still attached to the cooler! So I realized I just janked the Pentium CPU right out of its closed ZIF socket.



The horror. Really. You should have seen my face. :smt013



Ok. Spirits up. Cleaned the entire machine, and then proceeded to pry the CPU from the cooler to prevent having to force the CPU in the ZIF socket in its closed position.. But removing the CPU from the cooler was a real pain in the ass. As if someone used superglue to keep the cooler in place.. sigh... After a while I succeeded in removing the CPU, albeit with quite a bit of force.



Put everything back together, installed the PCB in the cab, turned on the power.. and prayed for about 4 minutes while the system booted.. And it worked again! No issues whatsoever. All running perfectly, except for the fact that the artifacts are still present..



The horror. Again. Seriously, man.. damn..



Ok.. so my next step will be to try out a few different Geforce cards I purchased.. Also might try Ace's suggestion of installing the original card in a normal PC..Keep your fingers crossed for me. I might kill it for real this time.. :smt012
