Working on an Asteroids Deluxe. The inside has a lot of dust. There is an angled mirror piece inside which is very dirty on the backside. There are two pieces of wood with screws that appear to be holding it in at the bottom.

Is unscrewing the pieces of wood at the bottom the only way to remove this for cleaning? Is there any other way to get at it?

Thanks.
 
There were the two pieces of wood and a bracket that needed to be removed. There was also a small dab of adhesive used at the very top which didn't pose much of a problem.

There was only half a picture at one time, then I reflowed the solder and the screen was filled and there were no problems. The chassis has never been worked on until now so I am guessing reflowing the solder caused something else to finally give way. The screen is now dark. I can hear the game playing and there's neck glow.

Anyone know if a cap kit will fix this? Is there anything else I should be replacing?

This game rocks...this game was located on a Naval Base somewhere (still has the Navy sticker on it), but I recently bought it from a guy who was in jail. There's always a story....

Thanks.
 
If you get a game this old and are in doubt if a cap kit has been done then do it... 'especially' if you have the monitor out already and are soldering on it. I do it on everything I get in without question.
Then troubleshoot from there.
 
Might as well spring for the filter caps too and make sure you get the cap kit with transistors. Is your spot killer light on ?

Screen is completely black. Sorry for my ignorance, but where would I see a spot killer light?

A "spot-killer" is a red LED on the monitor deflection board. The deflection board is the main PCB, likely mounted on the right side of the frame as you face the rear of the monitor.

It indicates that the monitor thinks that it is not recieving a signal, and is thus turning off the beam to prevent a burn-in spot in the center of the CRT.
 
It's probably a little hard to see it when its mounted in the game on an Asteroids Deluxe. You probably need to discharge the monitor and take out the HV cage and reflow the solder on it too. It's going to have to come out for new caps anyway.
 
I recapped the monitor including the transistors, and AR board. Game works fine now.

Thanks for the assistance.
