Hello all,
I've done a fair amount of digging to try and solve this one myself, but I'm not an expert on video signals and could use a hand.
New to the forum, but long time lurker. A few years ago I started my own injection molding shop. I do all custom runs, mostly my own products. I have 3 machines, and they aren't new .
So, my early 1990s arburg multronica decided to poop a tube. Replacement crts are $800 used, LCD kits are over $1500, and I think I've got it figured out how to diy....
The original tube was a Philips m24, monochrome green screen. 8.4" and 800x600 resolution. I pulled the board out, and the video chip is a tda2595. Looked up the datasheet and noted pin 11 is the composite signal in... I grabbed that pin and hooked up my o scope. Looks like the signal is a 20khz frequency. None of my monitors laying around can display it.
Can anyone point me in the right direction? I can post o scope images, modern LCD displays when plugged in, and anything else helpful.
Looking into frequency doublers and all that, but I don't know the first thing...
Thanks a ton,
Jason
