Hello, I have a 6116CD that only displays the green signal. So it looks like a green monochrome screen. If I wiggled the video connection sometimes would display all colors. I thought it was the connector so I replaced it but still only green and now if I wiggle you only see green. Any suggestions?

Are you using the HDI-45 port?
What connector did you replace? The huge adapters often get wedged against walls and damage the HDI-45 port on the computer, or sometimes the adapter itself. Sometimes the issue can be just a bad video lead though.
I'd get an AV card and a Sonnet upgrade and use that instead... but these days that will cost more than a 6100 :s
Yes the HDI-45 port. I do have two of the HDI-45 connectors and they both work on other systems. I think your right it was shoved against a way and put pressure on the port. Before I replaced it if you bent it down or wiggled it, you would get blue then all colors. I have checked the pins that are on the back side of the connector and they all have continuity. I didn't think of your idea of finding a AV card.
So based on your suggestion I looked at what was available on ebay. I saw this 6100 av and thought it may already have a card. I asked to see a picture of the inside and noticed what looks like a g3 upgrade. Seller doesn't know its there. I offered him $35 because his shipping was so high at $45 and I won it. Not even sure I care about the other board now. excited to see if that processor upgrade works. I can part out the reset of the machine or just use that board if it works. Thanks for the suggestion. I think I did ok.

Awesome.
Interestingly I think they haven't removed the logicboard cache, which you're meant to. It can cause them to fail to boot. Make sure you do, although it was really difficult to get out of mine.
It's either a Newer Technology upgrade or an older Sonnet, back when they used black heatsinks. I suspect the latter.
Another oddity, I don't know why, but my Sonnet card refuses to boot some OS versions - I forget which. If it crashes when the Sonnet extension loads and you have already removed the cache, try a different OS version.
One last thing - a cool thing with G3 upgrades in Nubus macs is that if you disable the Sonnet extension, it just boots from the 601. I have an Extension Manager set saved called G3 and another called 601. With Extension Manager set up to load before the Sonnet Extension, I can chose to boot using one or the other CPU by holding space bar during startup.
Thanks for the info I am sure you just saved me hours of frustrations. I did know about the cache, I can use it in another mac. I will post when it arrives. Cross my fingers its a 500, looking at pictures with the black heat sink that's what I am seeing but any g3 will be faster.

I'm just going to temper your excitement- my black heatsinked Sonnet is a 233MHz one. Just saying so you aren't too disappointed when it arrives
It's still way way faster than stock!
You were right to calm me down. It turned out to be a 225MHz G3. Still very happy and glad to have it. The case to the 6100/60 AV is trashed but everything on the inside works. It had a 1gig hard drive that is working well with no errors. 64mb ram, the cd rom and the G3 card and most of all working logic board that doesn't just display green. Pretty happy, thanks for you suggestion.I'm just going to temper your excitement- my black heatsinked Sonnet is a 233MHz one. Just saying so you aren't too disappointed when it arrives

An interesting side note. The G3 card was not being recognized by the computer and I thought it was the drivers. I took it out a few times and the connections looked good. Put new thermal past on the cpu, but nothing. I finally used a fiberglass brush and cleaned the connections until they were very clean and only then did the computer see it. Just enough age on those connectors to confuse the hell out of me.
