Hi guys,
My Hantarex MTC-9000 monitor died a week ago, and my Centipede has been down since then :'(
I don't know what failed so I ordered all the replacement parts I could find. I'm slowly installing a cap kit, HOT, and flyback on it thanks to the legendary Bob Roberts. I hope this fixes it, this is my first monitor rebuild!
Questions:
1. Where is the HOT? I can't find a manual anywhere.
2. I read a thread from 2006 about a fan with this model because of heat. Should I think about installing one? Mine didn't have one and ran fine without it...for about a month. The monitor is used and the chassis has had some repair work, so I don't know if it was age or what got it.
3. Is this a good monitor....I read a webpage that mentioned it was "the cr@ppiest arcade monitor ever made." I guess this last one doesn't really matter, but...

the horizontal deflection transistor(hot) should be a bu508 found sprung clipped to the flyback heat shield(underneath the big load resistor if memory serves me correct)
i don't believe the fan is needed with yours
its not the crappiest monitor,it just had a lot of silly problems.

Thanks to everyone that read and especially replied to this post. I replaced the HOT, flyback, & gave it a cap kit. I plugged it in, and turned it on, and was greeted with puffs of white smoke from the neck yoke. It really did die and my replacement parts & labor didn't fix it. Since Hantarex glued the neck yoke on the neck I think it's not repairable. What a mess, maybe I should try to sell my rebuilt chassis to recoup some of my losses. I only got two months of play out of it before it burned out, and I paid $100 for it, used. :'(
Too bad, the picture was excellent. On the plus side my soldering skills have never been better, and I know a lot more about monitors now. It's not really a silver lining though.
What does everyone do for replacement monitors? Buy used and rehab them? Buy a new Happs Vision Pro and not worry about it? Buy cheap cabs and steal their monitors? ???

Smoke from the yoke? Did you plug it in wrong?
-
No, I triple checked everything, the caps, the connections, the flyback, the traces on the solder side of the chassis, everything. So, so sad :cry:
-
I believe the horizontal output transistor needs to be insulated from the metal chassis on this model. Did you put a mica insulator and silicone heat sink grease on it?
-
thats strange,i've never seen a yoke do that before unless you somehow reversed the yoke plug-sometimes you win,sometimes you lose :cry:

Yes, the HOT is insulated and is on the same spot as the previous one. The insulation looks similar to duct tape, but I'm sure it's a different material.
