Been having problem with white screen on MC. Sent main PCB off and it was fixed/checked out okay.
Noticed two transistors burned on Reg/Audio board. R29+R30. Replaced but still problem. A knowledgeable person told me to replace TIP32 and the 2N3055 or the resistors will continue to burn.

Been having a white screen on Missile Command. Just noticed when it's plugged in, there is no "glowing" at the back of the tube where it snaps into the neck board? Is this correct? I thought you kind of would see some glowing going on at this point?
Thanks for helping a newbie!
I can turn down the screen control, that's no problem. I don't have another game sitting around or an oscilloscope so I'm kind of stuck. I did try another monitor chassis and neck board...but had the same problem.
Is there any other way to check the signal to the monitor chassis with a...

Any help/thoughts/etc. is appreciated. You will notice the bases etc. are burn ins and not the actual correct image.
Monitor is displaying white with a few horizontal lines. Replaced monitor chassis board. No change. Sent main PCB off (wasn't passing self test) for repairs, came back repaired...same problem. Check regulator/audio board, replaced two burned resistors, same problem.
Can someone direct me as to...
Hey Jbuck,

Hopefully I'll be able to distinguish the seperate tones. I really appreciate your help in this matter. I need to get this working again. Remove **** from email addy.
Thanks,

The self test gives me a raspy tone for about two seconds, a smooth middle tone for about two seconds followed by what seems to be one normal beep.
thanks for your help.
Experienced a pretty much total white screen while playing. Replaced caps on monitor and neck board - no improvement. Purchased a re-furbed and tested monitor chassis/neck board - still no improvement. You can see some horizontal black lines in the screen - it's not entirely white.
Can someone...
Replaced caps with cap kit. Also replaced two transistors. Monitor is still an even white across the field. The voltage on the red pin at the neck board reads 147 - I think it's suppose to be 160.
Any ideas or thoughts on where to look next?
Thanks,
I have a vintage MC arcade game in very good shape. Replaced the capacitors on a Kit from Zanen Electronics about 8 years ago. I played tonight (haven't played in a long time) and after about 10 minutes....the monitor is pure white. I'd like to try to figure this out myself, found this forum and...
