Resistance Measurement

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Resistance Measurement

Post by Goldstubble » Wed Jun 30, 2010 8:15 pm

Can somebody measure the resistance of RV2, which is where you solder on composite video in (see pic - credit goes to Erlex).
I seem to have misplaced my DMM.

On my NTSC board, I'm reading 75.5 ohms for RV2. Try soldering your video connection to the spot that zenloc's diagram shows. It is easier to solder to, and seems to be the only spot that works.

Double thanks! I'll give that a try.

Well, I did that and I'm not sure if it worked. My backlight from the LED mod works (which is good) and the sound works (which means the game is on) but I don't get video output.
Also, I could have messed things up fooling around with the surface mount resistors.
