Title: cd-base not working, what should I try?
Post by: batmreload on November 19, 2013, 08:19:51 AM: Finally got my ac-adapter for my base station, went to power it up with
a hu-card game (Double Dungeons)...

And nothing. No flicker on tv to show the tg-16 is even getting power. Ive previously
tested the TG-16 by itself and it worked fine. The adapter checks out, voltage and
polarity-wise (12v non-load, center negative)

I'm planning to open it up later, what should i be looking for?

I dont have the cd-rom itself, but ive been told the base should work without it, is this correct?

HELP!

Yanno, i thought i had tried that, but i tried it again, and Voila! IT WORKED!

Its currently pretty fickle though, and the video's pretty lousy. (dosent always
like to power on, picture's pretty noisy with some colors washed out) Time for a re-cap
maybe?

Thanks again! was about to give up!

Post by: majors on November 20, 2013, 01:16:21 AM: I recently had a system that came w/o a power supply. I had salvaged a replacement wall wart that seemed to check out (volts checked out, correct tip) but would not load games, just a warped green screen. I managed to source another power source and it worked peachy. I could only think that the amps were wrong on the first one, since I could not test that (I was going off what was written on the plug).

If you think you power is good, then you could open it up and look for corrosion or loose connections. does the CD base have a history? Simple test: does wiggling any cords make a difference?
