Monitor Repairs

WG 6100 Rebuilds

I’ve rebuilt a number of these now, but have not really documented them. I was fortunate to be able to pick another one up a few months ago for my Gravitar cabinet and it made it to the front of the bench. Turns out it has so much wrong with it I’m not sure how…

GO8 – Power up sequence

Disclaimer: My goal is to outline the phases I used to help troubleshoot my G08 without an all or nothing test every time (which could have gotten really expensive). The G08 FAQ V 1.14 has a vast amount of detail and was invaluable and needs to be read through completely. I’ve repaired a few GO8’s…

G05-80x / V2000 – Rebuilds

There are a few issues with the monitor. The owner told me the spot killer was on, I didn’t even try it myself. R100 and R101 had burned up and been replaced in the past. These can be bypassed per Atari. I checked the resistance and R101 was good, but R100 was failing and was…

Amplifone Rebuilds

When I got my Star Wars – I was lucky enough to get a 100% original machine that a Star Wars fan had owned for nearly 20 years and rarely used. Everything in the cabinet was original with matching serial numbers. At some point the Amplifone boards had some work on them, but pretty minimal.…

A few NTSC adapter repairs

I got a few of these to take a look at and either verify or get working.. These are for the G07. Under the dirt they seem to be in decent condition except for the width coils (I’m assuming – I haven’t much more than a 4 page doc on these) After cleaning up some…

GO8 – Chassis Rebuilds

My G08 chassis started as a learning experience which resulted in me creating a G08 Startup sequence/guide. Since then I have worked on a number of them for friends. My Star Trek G08 was #1… and after working on a number of them.. Why not document them too. G08 Chassis #2 – In for repair…

Donkey Kong – Monitor work

I didn’t get a shot of the game running, however.. After messing around with the TPG and getting it sorta running.. It certainly is a mess. It was all original. Pretty sure the dust was from the 80’s too.. No damage and it cleaned up nicely. Installing 33 capacitors took some time. Only my WG7203…

Ms.Pac-Man WG-13K7203

Ms. Pac-Man’s dead monitor The monitor looks brand new. Zero burn. Clean. Really a great looking CRT. A Wells Gardner 13K7203, certainly not original since it was built in 2000. Doesn’t work. First testing showed it is going into high voltage shutdown. I verified this with my HV probe. Shoots way up to 24K+ volts…

Working on the CRT

My machine has a working, but not very good looking CRT. At some point someone did a tube swap..  There is upside down pacman burn in – and two sizes of it.  Centipede had a swoop in the playfield from the top left down and parts were off the sides.. Research and friendly advice says…
