Kain3n Posted January 21, 2017 Share Posted January 21, 2017 so... i think i should have quit while i was ahead. the TV scoreboard was working with the RF video but picture was a little wavy, that's why I was going to try the composite mod on it too. when I tried it with the Telstar method you could tell it needed it's signal boosted because it was very faint as in the picture above and still wavy. so I think the wavy-nes has nothing to do with the video but decided to finish the composite mod and deal with the wavy later. i managed to find a place local here that sells the transistors and picked it up. and since i had all the parts already i tried to do it as the schematic i originally posted and boom nothing but black screen. i noticed i had damaged the trace leading to pin 4 Vcc (musta pulled on the wire too hard when soldering.) so i unsoldered everything and repaired the trace and tested it with a multimeter to ensure continuity. and tried to hook it up with the original RF connection to test and nothing but static on the screen now. can still hear the ball bouncing but no video i have metered all traces that i touched out for continuity and they are all ok so not sure why no video now... i am going to try it next with your 4 part way to see if i can hopefully get video. but i need a little clarification on the wiring. i have made a drawing of what i think you meant when you explained it let me knoe if i got it right or if i need to change something before i start. i am gonna throw this thing back together for now until i hear from you thanks Quote Link to comment Share on other sites More sharing options...
