Genesis Model 1 no video output[fixed] Help with S-Video!

[Ricky]

I was modding my genesis for s-video and then when I closed everything up and tried the to play a game nothing would come up.
Sound plays fine. I'm using the standard cable that comes with the genesis now, it has 5 pins, mono and composite out. Problem is no video.
I've checked and checked for solder bridges and damage but I can't see where the problem is. I've checked voltages out of the CXA1145P pins
and it is producing signals still. I'm sure this problem is caused by something so insignificant. I have checked all the capacitors and they are all fine.
Because the system actually works except for video I'm led to believe one of the pins on the CXA1145P are touching ground.

Any ideas?

btw I got a IC BD M5 USA mobo

Thanks.

Fixed this.

Chroma is giving me vertical lines.

Using 68ohm resistor and 220uf cap.

Double check your wiring and make sure you have everything where it should be. You tried both S-video and composite, right?

I tried both S-video and then composite. Neither worked so I de-soldered everything back to stock to see if I could find the issue.
Haven't found anything yet but I'm still checking. As for the circuitry of the S-video C line, I think I put the cap on backwards..
and I forgot the 68ohm resister before the output.. and I soldered the +5v to the emitter side of the transistor in the Y circuit..

Ok so I may have f'd up that but could it have caused permanent damage?

The cap being on backwards typically won't kill anything, thankfully. Pushing 5v through the emitter may have been a bad idea but I'd expect it to fry the transistor before frying the CXA1145.

I'd double check everything for shorts and then replace the caps around the video encoder. If all else fails I'd be happy to buy a dead Genesis from you.

the CXA1145 is definitely not fried, I'm sure of it. I get perfect mono just no video. I'll check all the caps again.
No bridges as far as I can see but my board is old and worn so I can't tell. Any references someone could give me would be greatly appreciated.
I'm going to go out tomorrow and buy a new transistor. I don't really care about money I just want to fix this.

The CXA1145 is not involved in audio processing thus it still putting out sound has no bearing on the video encoder being fried or not.

The fact it puts out sound is a good thing regardless.
