Av mod from coolretoprojects

[Popartliberty]

Hello coleco fans.  I finally got around to soldering the pcb mod to the colecovision and followed the instructions exactly, but I see nothing on the LCD television.

 

Does anyone have any troubleshooting tips for me ?

 

Thanks.

Is that the guy in Turkey? I;ve only used his Intellivision AV composite kits as I find his to produce the best overall results. But on the CV I've used the Retrofixes boards and those are excellent! 

As to your issue, make sure you still have it all working through RF just to make sure the RF modulator and the rest of the logic is still good. Otherwise there isn't much there to check. Just make sure nothing is bridged where it shouldn't be and that your grounds are properly in place. Also I don't grab the audio from the RF modulator, I grab it from the right leg near the upper right corner of the RF modulator near the back of the main board PCB.
