I have some issues with a couple of games that I want to get taken care of.

First my Zaxxon I've had since 2000, it's way overdue for me to get this fixed. I have attached a picture of the chassis I pulled from the game (this is what was originally damaged), Anyone recognize what it is? Or would it just be easier for me to take one of my working WG K7000 monitors and work it out to work in this?

Second my Asteroids Deluxe. It had been working but suddenly went out. Game plays, neck in the monitor lights up but no image. I have checked the brightness and nothing, I replaced those transistors that go into the side (which worked last time) but that didn't work. Not sure if maybe I installed those incorrectly? I thought I did but perhaps I made a mistake somewhere (or perhaps accidentally purchased an incorrect transistor?). Any thoughts?

looks likes your k4900 could use a cap kit as they all look original. what is you issue with it?

It's not visible on that picture but the chassis is cracked in the lower left. It's done in a way that I'm not sure if it is fixable. But knowing the number is a huge help, thanks!

Check to see if there's continuity from the housing of the transistor to the monitor's metal frame. If there is, you have a problem — they should be isolated. Is the spotkiller on? It's a LED on the deflection board. If it's lit, it means there's no video signal from the game PCB.
