Hi! I was hoping get some help. Recently my CRT monitor died and I was looking to replace it with an LCD TV. I know many look down upon this method, and I fully understand why, but right now, I lack the resources to replace/repair the CRT, so in the meantime, I figure I will use this 'band-aid' solution.
Anyway, I purchased this board off ebay.
Naturally, it didn't come with any instructions, I asked the seller for more info, but he was unable to provide any assistance. I found a site that kind of explains what I have to do, but it doesn't really go into great detail on how to do it.
The board came with these wires:
I figured I would have to splice the VGA Wires
I cut the above from the Jamma wiring and spliced some of it to the "Links To" photo above.
The Easy Part - I was able to match the Red, Green, Blue and Ground (White+Black) wires with the help of the Jamma connector. It had a chart/diagram labeled on it, it was just a matter of following the colors.
The Hard Part - I have 2 extra colored wires, the silver and Yellow. According to the Jamma boards website, I know that these are the V Sync and H Sync, however I've looked all over the board (and checked the diagram), there are no wires on the Jamma harness that have this attribute. There are some connected on the actual monitor, but that's independent of the Jamma wiring (and correct me if I'm wrong), therefore shouldn't be considered? There is a single wire that says SYNC, but that doesn't really cover what I am looking for, right?
Problem 1: I have the RGB+Ground connected, I tried to test it, but it wouldn't work. LCD reported no signal (which I expected). I don't know what to do at this point. Has anyone performed a successful conversion? Your assistance would be greatly appreciated.
Problem 2: The Red + Black wire, it says to connect this to my power source. That doesn't really tell me anything. Does it mean splice it into the Power supply? If so, where? The wire thickness is totally different from the power supply wires. I'm afraid if I do this, something bad will happen. Theres a Black and White wire that connects to the monitor (I think it's the isolation wire)…I wanted to try to tap into that, but something tells me to avoid that at all costs…
I'm clearly over my head here and in need of some help. Any assistance will be greatly appreciated. Thanks you in advance!
