ok not sure if this a monitor question. just got this game and nothing on ther screen popped open the back and touched the connctor to the chassis and it fired up. the screen just has raster lines going vertically and i can change the color of the screen. would this be a monitor issue or a pcb issue? monitor is a wg7915.. can i try a standard res monitor to rule out it being a monitor problem?
 
he is a pic of the screen, doesnt look like it is getting a siqnal but is hooked up.

Make sure the neck board is pushed on all the way. After putting a cap it in the other day, my centipede stopped working. So i changed out the Hot , the flyback, the width coil and several other things. Still playing blind. After several times of taking the boards in and out i Finlay figured out i was not pushing the neck board on far enough.
 
neck board is secure. i just adjusted both boards to 5v. its was running at 4.34 . still no picture just a blue screen. someone hacked in a swither to run just the 5v
 
fixed this vid issuse, checked the schmatic and a 15 volt wire wasnt hooked up to the video side of the board.
