Hi all, first of all let me say thank you to those who helped me get my Centipede up and running. I'm new to this site, and you are invaluable,

I have just acquired a battle zone caberet in fantastic condition. Very clean inside and was serviced in 2017. It has the sense mod in place, and the big blue has been replaced with a big black.

The game seems to run when powered on, start button flashes, when pressed engine noise responds to controls, fire button works and explosion sounds can be heard.

When going into test mode I get a high beep followed by a very short lower beep.

The main problem is that there's no image on the screen. There is a spot in the middle which I have viewed briefly before turning it off to avoid any phosphor damage. The spot killer light is lit on the PCB. I've tested XOUT, YOUT & ZOUT with a logic probe and get activity (jittering between high and low), and a signal with the digital oscilloscope, but only very low voltage on DMM (almost zero).

Has anyone got any idea where I should start? I've ordered a cap kit for the monitor PCB including replacement transistors, and I've heard that resoldering the connectors is a wise move. I've got a HV probe so fine with discharging the vector tube and know the risks (1Mohm resistor etc).

Many thanks in advance.!
