this is what should be in that cable
simply adding a 75ohm to ground from each transistor output should make it work with the caps in the cable

Quote from: turboswimbz on 09/07/2015, 08:27 PMSo I was able to snag these sweet piece of plasma PVM.
50" Pioneer PDP-503CMX with PDA-5002 VIDEO CARD.
I'll have to get better pictures of it working when I get it all set up.

Console Repair/Mod Center / Re: PCEGT replace with 3.5inch TFT LCD
07/22/2015, 11:11 PM
Quote from: wilykat on 07/17/2015, 01:42 PMthe only issue is those encoder chips would need the inputs enabled in softwareQuote from: thesteve on 06/15/2015, 04:54 AMI got in LCD for the mod. When I checked the video chip AMT630, it supported both composite and S-Video. So I was wondering if it'd make mod a bit easier or if I'd end up needing 2 transistors to amplify both Chroma and Luma ? If it can be easier, it may be worth going that way instead of the usual composite route. If not easier, I'll go composite route as it's hard to see difference between s-video and composite on a 3.5" LCD.
Too bad 3.5" LCD with analog RGB is virtually nonexistent. That would have been very easy mod since there are RGB connector for the original LCD.
you would need to edit their programming

also the bars are native to the system, solved by 2 caps
Quoteawhile i figured out a jailbar fix, but was waiting for further testing
the fix is placing a 22uf ceramic or tantalum cap from the HUc6260 pin 41 to ground, and another from pin 43 to ground.
