Dark RGB lines

Klefmung · Post by **Klefmung** » Fri Jan 12, 2007 3:34 pm

on my fc twin, the rgb lines work, but they are dark.... like, a bit too dark. >_> I guess a cap is the solution, as it usually is with rgb, but at what rating?

220uF 16V should be fine

thanks. I also confirmed one thing about the FC twin: some of the video encoders are faulty. Because the composite ceased to send out anything BEFORE I removed it from the case.

Does yours use a CXA1145 encoder like hailrazers?

nope, CXA1645M

Well thats a better chip, cleaner picture than the 1145 and it does s-video. I'm not positive if they are drop in replacements though. Maybe thats the problem.. pirates.

This must have been the problem I was asking about weeks ago when a guy at the fleamarket told me these were unreliable. He said a lot of them failed shortly after purchase.

By "failing", he must have been referring to the dead video signal Klefmung is talking about.

well, by any means, this discovery needs addition to the sticky!

I'm really anxious to get mine so I can take it apart. I dont plan on modding it right away, but i do want to check everything out. I'll let you guys know what IC mine has.

For the record, my FC Twin also used the CXA1645M IC. Its a popular encoder, used in lots of consoles including the PS1. This IC supports s-video out for those that want it.

so can we get a pic or something?

I would like to know about this FC twin some more :rubs hand and dreams of flea marke fortune:

also can you dispell the NES portion to not run on that encoder...I know it is true but need to be 100%

hailrazer has some pics in the other thread. Unfortunatly I already put the thing back together so I cant verify the noac doesnt use RGB, but next time I have it apart i'm going to start tracing things. Ill post the info if someone else doesnt beat me to it.
