bad flyback on roadblasters

[cyruszain]

hello, I just picked up a Roadblasters upright.....I plugged it in, no video. I looked at the video board and saw a blown fuse...replaced it, plugged it back and saw a beam of light through a few cracks in the flyback with a howling whistle before the fuse blew again.
I am new and learning. Would it be wise to just replace the flyback(and a cap kit) than to replace the whole thing or could it be useless to do so as there may be more problems now? There is major burn in to consider too. I was given another chassis and monitor but i can't see how to hook it up to the motherboard.
appreciate any input
thanks

And the make & model of the monitor in question is.....

DUH!!  sorry, i thought there was a standard monitor/chassis in those from the few other posts i read.

i am going to take a pic later...i think it may have been changed out at one time.

the burnt board has an ID of 85x0216-00***(can't read the last few) 
 w.g.e.c 1986 
 it's a philips tube   
 a tag that reads chassis   Uro4260 ?
the flyback in question is a Murata  30am690z (if i am reading it correctly)
I read another post with the the same board ID(though the pic was not the same) and a reply ststed it was an Electrochrome G07.

The one given to me....I haven't the foggiest idea what it is....i shall take a pic.
It has no disinctive markings on it for reference taht i have seen.

let me know what else is needed...like i said...i am still learning.
i will post pics later tonight
thanks

anyone know this board?   the pic of the roadblasters board is too poor to post. this board is from a monitor/chassis that was given to me. I was hoping to hook it up to the roadblaster game but i cannot figure out how to wire the game to the board.
thanks

Wow--you should talk to RayB and see his thread just a few threads down--it looks like the same oddball eastern micro that he has (what are the chances that two of those things show up at the same time here..)

Getting the flyback may be very tricky--just google search the flyback numbers six ways from sunday and see if any pop up also look here:

poke around that site and see if something matches.

My friend Steve Mildenberger has several Roadblaster games on his route. They all came from the factory equipped with Wells-Gardner k7000 monitors, but remember that with any video game, someone may have replaced the monitor with a different one over the years.

well.....i am learning little by little here.

here is a pic of my Roadblasters monitor/chassis. You can see what i am faced with. The Flyback is definitley bad and the monitor had severe burn in so i am going to change it out. the 2 are harnesses are  as they were...1 disconnected and does not seem to go anywhere on the board, the other in a logical place based on the games schematic. ...  I am slowly getting familiar with this.
That is where i am not catching on in the articles i have been sifting through, where those harnesses from the game would connect to in another chassis. I have seen only 2 others...the other oddball one pictured and another a friend has in an empty cabinet he has had...neither look compatible.
is it wise to go through the trouble of replacing a flyback..wouldn't there be more damage elsewhere?

Apparently the chances are good today...it appears it is the same!  after seeing that thread i was able to poke around the PC boards some more until i found em-201 stamped under the clutter...it appears to be the model# so i am happy with that...now to go over the schemtaic a little bit.
thanks for pointing that out to me.

The board you pictured in your last shot is a wells gardner k7000 series and the plug you are holding is the red green blue inputs.  I was confused earlier and thought you had the eastern micro board already installed in the roadblasters.  If its the wells installed I would highly recommend getting a flyback for that board (still readily available from bob roberts for about 25 bux).  I only say this because after market cap kits and schematics are easily found for the wells board but doubtful for the eastern micro.

I had a k7000 with a bad flyback and it popped fuses like popcorn--one trick Ken L showed me to confirm that it is the flyback was to remove it (the flyback), then briefly power up the tube--if the fuse stays, it was the flyback.

the flyback has a few cracks in it and looks like toast, so i am guessing it is time to replace it. I am just concerned if i go through the hassle of replacing it that i find additional problems, but i'm sure it'll do the trick. I am ordering an kit.
I DID hook up the em-201 to the game. The anode cap will not stay there though. I am googling for info on that now. the cap stayed a little and i got a recognizable  reversed, fuzzy ,dim image...but it was there.

i see a ton of info on removing the anode and dishcarging, but nothing on reinserting the anode....still doing research though
cheers!

to apply the anode back in:  with your finger and thumb, fold the rubber back on each side of the cup so that the prongs are sticking out, insert the prongs into the hole in the tube and release the rubber (which should snap back into place)  If its not seated correctly you will get volatge bleeding off the side of the cups and potentially etching the tube (very bad)  you will also smell ozone if its not seated right.

You aren't trying to hook up the em-201 chassis to the k7000 tube in the roadblasters are you? You should be testing the em-201 chassis on the em-201 tube sitting outside the roadblasters cabinet with a power and input hooked up. I don't think trying to use the em-201 chassis on the k7000 tube would be the wisest choice.

No, lol , i hooked it up outside the cab.
i actually put that aside now and am looking for either a new chassis or replace the flyback....anyone in MA, USA who can help either way?
