Monitor Accident

[Antix]

Hey all,

Well, I decided to move my cabinet on a whim after a few too many drinks.. Something I had sitting on top, which has never moved before, fell down the back in hit the end of the monitor, knocking off the little circuit board that connects to the end of the monitor. (See attached pics) Some of the white plastic inside the centre circle of the little circuit board seems to have been the only thing that broke. (that I can tell anyway)

Now, I don't know a lot about monitors, apart from what I read online. A lot of that tells me all about death and massive amounts of voltages. So, I tried to connect the little board back on. (Once sober of course) The screen seems to power up, but I just get black and white blocks, no colour, and no shape or definition to what was there before.

The monitor is in a big red cab, and is a zenith 25" monitor. (The 2 numbers on the tube are, G-A63ADG25X   04RC0105-005)

So, my question is, have I killed it? Or, have I just not connected that little circuit board properly? I took it off for the photos in case someone can say "hey, that bit should go there" But, to me, it looks pretty obvious with that sorta triangle shape should line up with the other triangle shape right? (Technical terminology is one of my strong points!)

If it appears to be toast, what should I look at replacing it with? I live in New Zealand, so there isn't a lot of places to go looking for monitors, they occasionally turn up though on our equivalent to eBay site. They would just be second hand ones though. I only really require a 15kHz monitor as all the games I run on it, through Mame and the couple boards I have, work fine. (thanks to Soft15KHz... awesome tool!) I can wait for one to show up, it isn't super urgent... although, I will miss it)

If I have to buy a new one, do I just need the tube? Or do you think I need to replace that circuit board as well? (when powered on, the machine makes a really loud squealing noise until it warms up, so if I have to replace where ever the hell that is coming from, that wouldn't upset me too much!)

Any and all help greatly appreciated

Cheers

Maybe it's the angle, but it looks like one of the neck pins has sheared off. 

You may be able to solder in a jumper if there's a nub sticking out, but otherwise you may be stuck finding a new tube.

pin 11 would be the blue cathode ....

OK so I had another look. The one that looks like there is no pin, there is no pin. However, all the ones where there is a pin, has a wire that goes from that pin up further into the monitor neck. There is nothing like that from the one that has a missing pin.

Poked around a bit more though, and the circuit board is actually cracked, I can bend it, the crack goes from one side to the next.... Im guessing that is not a good thing If you zoom in on the pic, you can see it by that little yellow thing on the right. it goes right to the other corner, bottom left.

Looks like I have to find a new monitor, and all the boards etc. Guess I better try and learn how to replace that... when/if I find one.....crap.

Or you could fix - or have fixed - the damage...

Just get a new flyback, right?

Just get a new flyback, right?

Get a new flyback for a cracked neckboard?

[Ummon]

Oh. Obviously I'm confused about the parts. I should say 'get a new neck board'?

[SirPeale]

Likely he can fix the one he's already got.

Not sure I would know how to do that, but will do some searching on the net.

Have started asking the arcades around the place if they have spares or do repairs, but there arent many arcades left... mostly just one chain of them here, and they havent responded to my questions.

Thanks for the responses

OK, I have been extremely slack, and completely encompassed in real life. No time to even think about repairing this thing.

However, it has gotten so that I just need to get my arcade gaming fix, that, and the wife is starting to make noises about getting rid of the machine as it doesnt work!

See pics finally.. attached.

1 shows the yoke wires. pretty sure that is what they are, 4 of them blue, red, green and yellow.
2 shows the two red wires, and a black on with a connector at the end. Dont worry about the light bliue and all the others, just these ones in the middle.
3 shows where the wires from 2 go. The two red ones go to a collection of wires in front of the screen, behind controls really, and the black one seems to go around the monitor tube.
4 is of the chassis where I would presume all these need to connect to somewhere.

I have no idea where these all go.

I have been trying to find people in my area that could help fix, with no luck so far, Im in New Zealand. I have been looking out for monitors to replace this one, or complete arcademachines to replace this one, but they are either too expensive at the moment, or, I have no idea if the monitor being advertised will fit, or, if I need all the other parts as well, chassis, neck board etc.

Posting these here as I had another thread talking about the way this cabinet was left after someone tried to fix it, but I cant find that post, some people said they may be able to help tell me where to connect the wires if I posted some more pics... well there they are.

Thanks for anyones time
