Hi all,
I'm working on another project here, and though i'd ask for a bit of help. I don't have much experience w/ video signals and all the different converters on the market, but I feel like i'm close on this one, and looking for some help to finish it up.
I have a few injection molding machines, they are older, and one tube went out last year -- and it has been a problem ever since (see my other thread). Trying to be proactive on my other machine, I took it apart to figure out what type of monitor is in it and evaluate how i'm going to swap it to a lcd.
The machine in question is a Niigata 110EU. It has a 15" tube made by toshiba (model e2971b22). The board looks pretty simple this time - the signal input is 6 wire (RGBESV) my translation is Red Green, Blue, Earth, Horizontal Sync and Vertical Sync... Looking online, I found that the CGA,EGA,YUV GBS8200 model converters should be able to help me get the signal to VGA.
I bought the GBS8200 - and wired it in. After some screwing around with the horizontal wire on P11 I got it to semi-work. FYI, pin 11 on gbs8200 is (gnd, gnd, vs, hs, s, B, G, R). I now have the horizontal sync going to the HS position as opposed to the S pin..
See this video for what is happening:

My assumption is that my signal is ~15khz. I'm thinking that the gbs8200 initially boots into 15khz processing, but the automatically switches to 24 - 30khz to lock onto a signal. It must not figure out my that my signal is 15khz and just jumps to the next auto sync... I've read that you need to have 2A on your 5v signal -- i have a 5v 4a power supply. I've read that the caps can be junk, so I am going to replace them next on the gbs8200.
I'm opening to buying one of the fancier converters (XRGB mini, OSSC, etc) but figure may as well give this one a try, since I already have it. And it looks close.
Also, if you have any interest in solving a giant pain in my a$$ look at my other thread.
Thanks a ton for your help. I'm learning a lot. Tinkering is fun. next on my list will be to replace the monitor on my haas.
