The Dokert/Chris25810 Busted GO7 Challenge/Donation Contest

Several weeks ago, Dave aquired a frickin mangled GO7-CBO chassis that he started a thread on and jokingly offered it up to me to see if i could do something with it. I took him up on the challenge and told him that if i could repair it and feel comfortable that the repair would hold, i'd donate it to someone here that really needs one. This was definitely the most amount of breaks i've ever repaired on one of these things and honestly, it looked much worse on the bench than it did in his pictures.

Every flyback trace was broke, and the upper right corner had two other large breaks. There were several broken small traces in the deflection area and of course it was cracked on the video side just in front of the frame. It took a shitload of solder, cap legs, a few wires and some epoxy but this thing has been running on my rig for several hours and it has a rock solid picture with a perfect B+

The other issue at hand was the previous rebuild on this mess. The rebuild work was mediocre at best, (sorry if i offend somebody here but it was quite shitty) the anode clip was ripped off the flyback, you needed a microscope to see the solder on the replaced caps, the insulator boots on the focus tower are all ripped and somebody figured wads of electrical tape would be a great repair. I normally wouldn't fix a chassis like this as it's hard to know how people are gonna handle it on an install basis and it's hard to know if the repair will even hold. The only reason i tried it was because it has alot of new parts already and i was bored with the typical chassis repair thing.

This is being donated to somebody here that really needs it. We're not quite sure how to go about chosing the needy one but my initial rule is that you have never bought or had one of these repaired by myself or Dave.


This chassis comes with:

A fairly new flyback

Newer caps (including filter cap and bi polars)

New width coil

New R908

New F901 fuse

A little bit of grime, alot of epoxy, cap leg bridges and plenty of added solder.

Here are the pics of the Chassis that I sent to Chris25810 about a week ago.

That thing is... beat to hell.

Good luck with it.

But don't you think the cracks add "character" to the board? lol... "it's all original" like that Castlevania that is broken and worth less if fixed.
 
very nice

I will put my name in the hat for needing it if you have a drawing or something.
 
Honestly, that doesn't look all that bad. I probably would have repaired that as well... all the components look fine, just the board is cracked in a bunch of places. I've got several that are in worse shape than that, though I just throw them into my parts box (they probably got stepped on, or had stuff dropped on them, because the boards are cracked, and a bunch of components are damaged).

I'd much rather fix that, than try to fix the electrical equivelant of that much damage (dead chips, randomly opened transistors, diodes, etc). I assume it just needed a bunch of jumper wires and some physical supports?

Here's what it looks like after a couple hours worth of frankenstein stitching, this will win no prize for vanity but it does produce a beautiful picture.

I have a few that are worse. I'd never attempt to fix them though, it's just not worth the effort unless you're insane, like Chris clearly is :)

I bought a bunch of boards from a guy once, he had them all stored in those large plastic 'totes' (I hate those things). Basically, he just jammed the chassis' down inside of it, so many of them have cracks like this on both rear edges of the boards as they folded up in little balls to fit inside the tub.


I will say though, this is the worst chassis I've ever seen anybody actually REPAIR, though, lol.
 
And here I thought I had a challenge for Chris25810. Silly me, I just should have tossed this chassis in the shit can and called it a day. (NOT!)

Damn that is inspirational
 
Rule #2 This chassis comes with absolutely no warranty. It may last 5 minutes or 5 years but either way, i don't ever want to see it again. If you need over the phone help installing it (for noobs only) i'm happy to help you but if you break it or somehow mess it up while installing it, you are completely S.O.L.

Damn. I thought you sent him a bad one. :cool:

Perhaps your judging should be based upon someone who can give you the best "my game has been broken for so long because I can't figure out the damn G07 repair" story....

I kind of like that.

Rule #3 you do NOT need an exchange

Yeah I think that would be a good idea.


Another way you could judge it too, is since it's such a beat up p.o.s. chassis (but still functional!) maybe you could give it to somebody who's got the biggest p.o.s. game, that they actually want to get going and keep.

Kinda like the Charlie Brown Christmas Tree.
 
If you're gonna do the exchange thing Dave, the returned chassis should go back to you since you initially bought this one and you paid to ship it to me.

Ah hell no, I don't want anything back. This is a donation.

fixed it.

lol

This is a great idea. A "Pimp my Ride" for cabs.
 
Wow thats amazing:eek: I need a few G07's and would like to enter the contest. Unless buying parts somehow disqualifies me:rolleyes: oops I read the rules again Im disqualified for buying parts, I knew it :)

Again Chris amazing job!!

You guys can stew on this for a while and i'm gonna go to bed. I still have a few things to tidy up on this and i want to log a bit more runtime on it before i let it go. This should give you guys some time to come up with ideas and maybe someone will come forward. My last Rule of the evening is this:

#4 Shipping will be to the continental U.S. only! I already have enough time into this thing and i have no interest in standing at the post office filling out paperwork to send this to Canada or overseas. Love all you guys up and over there, but not that much.
