Asteroids - Sizzling sound and nothing on top half of screen
So I picked up an Asteroids cab today (G05-801 monitor). The person said it was not working at all, but the cab was in decent shape and I used the lack of function to get the price way down. I started fiddling with it when I got home. Just by making sure all the connections were secure I got it to power on.
However it has some issues with the monitor. When in game mode all that appears on the monitor is either a single dot in the center (picture attached) or a horizontal line of dots through the center of the screen. These dots are consistent but the player start buttons blink. If I put it in to test mode I get the test grid, but only on the bottom half of the screen (picture attached). the test grid blinks during this time and the player buttons are constantly lit.
Due to the blinking I am thinking there is a power issue and I am planning on doing a cap kit on the whole arcade (monitor, power, game board, and sound reg).
There was one additional issue that has me a little spooked and is the main drive for my post. When I was doing the run in test mode I started to hear a 'sizzling' sound (that doesn't really accurately describe it but I can not think of a better word). There was also a brief burning smell, that went away but the sizzling sound didn't. Only taking enough time to approximate the location of the sound, I turned off the power. I let it sit for a while and then switched it back on, the sound started up immediately, so i switched off the power again.
The sound seemed to be coming from the blue monitor caps, (picture attached) but it could have also been coming from the tube.
Any suggestions on what the sizzling may be would be greatly appreciated as I am now a little worried to turn the cab on in fear of something getting damaged further.
Any suggestions regarding the other issues would also be greatly appreciated.
