it was actually just wiring up to the correct ribbon pins and hooking up to a DB9.
However - I am now having a problem. All the mods I have are set and working properly, however I am now getting really bad interference, it isn't too bad until the screen is black or very dark. I get a lot of wavy lines / interference. Hooking up to a TV via S-video, I am seeing the same interference although not as bad.
Here is my thoughts (and let me know which one to chase first):
The cheap ebay LCD I bought is junk, and is causing the problem
The DB9 controller port is causing the interference
The SMS mode modification is the issue (the last mod done before doing a test and noticing the issue)
Now my LCD isn't energy efficient, I am not getting as much battery life as others have on the same Lithium Ion battery. I am thinking that it draws to much energy, and maybe the cause of the issue? If I disconnect the screen that should indicate if that is the problem (and S-video to the TV doesn't have a problem).
I might hookup to the PS1 LCD and see if I get different results.
Let me know your thoughts, kinda frustrating because I have spent so much time trouble shooting this one. I put in a shielded cable for the composite video line, and although the video slightly improved it wasn't by much.
Thoughts? Anyone know of a good quality 3.5" screen for the nomads?
