WG K4600 that won't power up

[Crowquill]

I bought this cabinet about 13 years ago and it's mostly sat at my parents ever since. I bought the game non-working with "Crazy Kong" artwork. After sitting around for a couple years it got a new power supply and to our surprise on powering up it was a "Donkey King Junior" board (DJ Jr clone). After moving the cabinet 200 miles, I could get a crackle and a bit of a hum when I powered it up, but discovered that somewhere in its moving the PC power supply attached to the board was missing.

I carefully leaned the cabinet onto its back so that I could replace the bottom panel and reinforce all of the joints that were coming loose. After tilting it back up I attached the new power supply and tried powering up. I get no response from the monitor now. I can't find my multimeter but it seems that I have continuity between the blades of the wall plug and the splices right before going into the monitor. It should be getting power and the splice comes after the fuse that's wired in so that's not the issue. Where should I start looking to get the thing going?

The model number is 19K4675.

I'm guessing at this point that the monitor isn't worth saving. The neck board was apparently cracked and carefully soldered back together in a maze of wires. The tube has excessive screen burn from both Zaxxon and Side Arms. Being that Side Arms came out in '86, this monitor has to be a transplant anyway. The cabinet's wiring as a whole is done badly, and I'm still trying to figure out why the wires for red, blue, and green are soldered directly to the neck board. Sync and ground are connected to the normal connector.

If the monitor has not had a capkit then get one first.

While a popped or damaged cap would obviously stop the flow of electricity, I figured I should at least hear some noise from the tube/yoke. While I''m sure stranger things have happened, how can laying the cabinet on its back could damage a cap?

Newbie question of the day: is the power routed through the main board before hitting the tube?

What else could cause a lack of power?

[Ken Layton]

A bad cap can cause the high voltage xray protector to kick in thus killing all voltages in the monitor. This chassis is well known for many bad solder joints, especially on the main monitor board. Sometimes laying the cabinet down or simply moving the cabinet across the room knocks the two plugin circuit boards loose  so reseating them may help.
