So I acquired a small Rambo cabinet with a lindbergh that tried to boot once (albeit superr slow), and then froze into a bios screen about bad cmos battery loading defaults.

I rpoceeded to replace the cmos battery, a d even though the machine apears to boot, I am nkt getting any video. I am about to test the power suply to verify proper voltages, and then ill see if i get somewhere. If I dont, I guess my next step is to change video cards. As such, my question is.

WHAT video cards can I install on this red lindbergh EX that are compatible.

Thanks in advance.

P.s. any troubleshooting tips are welcomed :)

So just to be clear, you saw video and it told you that you had a bad cmos battery?

Then, you replaced the cmos battery and now you can't see any video at all?

There's 2 batteries to replace, one on the IO card and one on the motherboard, but either way you can get past the boot without replacing them by pressing CTRL+ALT+S and just pressing escape and moving past that screen. ( you may need to remove the mini usb connector panel to access the regular usb ports to connect a keyboard)

You will need to replace the GPU with the exact same one as the original, basically from another red Lindbergh. But clarify what happened with the cmos battery change. If you can see the bios boot screen, then it's possibly not a bad GPU.
 
after cmos replacement, i see the pc fans spining, but no video signal at all. i only saw vid signal once, and that was it :(

and yes, have a small form factor rambo cabinet that can would also be perfect for hotd 4 :(

Something may have died... The only thing i can suggest is to unplug the ram/gpu/sound/io card and try to clean the contacts. You can use isopropyl alcohol and an eartip, methylated spirits can do it but its not as good... or an eraser just give them a gentle clean and reseating. Reseat them a few times. The ram especially. Try powering the unit with a standard pc power supply if you have one. See if that helps to rule out the PSU. You dont need to connect both power connectors, get a regular pc power supply and just connect the single large one on the left, it will still work fine. Failing that if you get no post, then it sounds like some sort of hardware fault.
 
So I ran some test. I read a sugestion to run tue machine with a low end gpu to wee if at leastnIncoukd get it to post... if it did, thrn likely it was gpu.
I ran this test. and i did get the kachine to boot (i promptly powwred it off, since it would likely error out)
aso as it stands, its likely the GPU.
At this point, I either find a compatible replacement GPU, OR TRY TO TURN THE SYSTEM INTO A MULTI. Any sugestions on how to proceed?

Make sure you check the 12V output on the PSU!!! this is critical on Lindbergh setups.

Lindbergh is a PC and Sega used an Arcade style power supply with it. The problem is on a normal Arcade PCB the 12V rail is used for things like cooling fans and audio Amps and will be OK if the 12V rail is way off (10V-14V range is usually fine). but NOT on Lindbergh, Particularly the GPU needs the 12V to be nearly exactly 12V or it can cook.

this is why so many Lindberghs have dead GPUs... the PSU 12V falls out of adjustments and the GPU cooks from over voltage. and then if you replace the GPU you risk it cooking again if you don't fix the PSU.

So
#1. check your voltages, including 12V to ensure it's in range.
#2. install a PC ATX PSU for powering the Lindbergh to avoid any voltage issues with it. regardless of #1 to be safe
#3. if the GPU is still giving you issues, remove it, clean the dust out of the FAN assembly and replace the thermal paste. Inspect it for any burn marks or other damage.
#4. Once you've done the above then if the GPU is still having issues you'll likely need to replace it with a working unit from another Lindbergh.
