Bah! 2600 Video Out Half-Failure

[AtariKari]

After much cursing and a fair amount of rosin fumes up my nose I got the video mod on my Junior from Ben Heckerdorn's awesome site: http://www.classicgaming.com/vcsp/ up and running. Sort of.

 

It works fine on one TV I have, but my main television cannot display the video. I'm guessing, similar to the mod here on AAge, that I have to boost the signal somehow. My TV is a new RCA 27" and I have tried running it directly into the back of the TV, and through a video tuner box thing but so far no luck.

 

The audio works fine, and I can get a "pop" indicating that the TV is recieving a signal, but nothing else. I'm all out of ideas and have no idea how to build a signal booster but would give it a shot if anyone could point me in the right direction. The most frustrating thing is that this is my only system, having sent my spare off to Junie's

 

Any help is appreciated. Thanks!

Buy a signal amplifier at Radio Shack. You will also need a couple of RCA to F-jack converters as the amplifiers invariably have F-jack connectors.

 

If you want to build your own amplifier look at the S-Video/composite mod in the 2600 FAQ, it includes a basic amplifier.

Thanks--the video amp from Radio Shack drives the signal, but just barely on my TV: it takes several seconds and a few tries to get it up, but man is it crisp. Sort of.

 

I resoldered the setup with thin wiring and little solder. I now have a wavering image, with a fair amount of garbage on the left side. Also, the picuture has shifted down and to the right. Where on the board do I go to work on this?

 

Again thanks, I'll put up a photo of what I have if anyone is interested. This is a fun hack, but since there are so many ways to do it I'm not sure where to go from here.
