So this morning I finished putting in a repaired monitor back into my PC-10 (Had the control pannel on the back replaced). Everything is hooked up right etc. But obiviously I screwed up somewhere cause one I turnned the bad boy on, all I heard was this big POP noise, not from the speakers. Turned of and unpluged everything. Then took the back off, and the cab smelt a little off, push the OMFG why do I see smoke.

First fear, thought I may have fried my mainboard. So I pull her out, thats when I noticed my filterboard had a short circuit. Which fried atleast 4 differnt points on the board. I'm not happy but I'm upset enought for me to want to walk away from it.

Now I need to A: figure what caused it before I do anything else. Could have been the repaired monitor, but I doubt it. B: I have to get me a new to me Dual Monitor Filterboard. Yeah.....

Anyone have any Ideas what would have caused the filterboard to do that?

If I have this in the wrong spot, let me know. I will delete and repost in the proper section.
 
I've never tried it before. I guess it would. But I will hold off till I figure out what caused it.

The board could be repaired. I'd have to solder a line from the connection point to the edge connector. As it actually blow portion of the copper right off the board. Crazy...
 
Did you plug the monitor back into the special 100V isolated outlet in the cab or did you accidentially plug it directly into a regular power outlet?

Did you accidentially reverse the two identical connectors on the sound board on the monitor chassis?

Was your harness not keyed and you plugged it in backwards on the filter board?

I'm leaning heavily towards one or the other of the first two which could send 100VAC back to the gameboard.
 
That sucks.

Your monitor is toast as is your game board. The monitor probably is more repairable as it probably just blew out the bridge rectifier and possibly the HOT. But I am not as familiar with the Sanyo's as others.

As far as the game board, you have 120 volts AC at at least a few amps going through 5 volt to find the fastest path to ground, that's why it torched the traces. I don't know if you can recover the board from that. Ken Layton may have tips to narrow down where it MAY have gone.
 
LOL, my day justs gets better. I have to laught, cause if I don't I just might cry. lol

I don't even know what to say. I think I may just close the door to my game room and not go in there for a week.

What do you think, I had one game on the board. Would it had done anything to it?



Sigh........... a learning mistake.......
 
Just for knowing reasons what does this look like?


- "Did you accidentally reverse the two identical connectors on the sound board on the monitor chassis?"

I know the sound on a Sharp is red/white and comes from the transformer mounted on the monitor PCB. Is this what you are talking about? And if so what is the identical connector?

Or is there something different on the EZ monitor?

- to the original poster - sorry for your troubles. these cost way too much for bad things to happen.
 
I look at it this way, I am a Newbie. This was a costly mistake.

Best case, I can fix the mainboard. If not and if the ppu still works. I will do a NES RGB mod. I have extra single monitor boards my friend has been asking me to do a straight swap for his extra dual monitor pcbs. So if hes still up for the trade, something can be saved from this.
 
yeah that really sucks. I just rebuilt my dual monitor punchout and made sure i plugged the monitors into the correct plugs. Sanyos are a pain in the ass to begin with.

You should definitely do the trade if you have the opportunity.

Yeah... he should ask him. Ho wait, it's done already, and it's a yes! Sorry for the situation and I'm glad to help out.
 
You may have torched a gameboard and monitor, but holy crap you may have saved 50 other units in the world just from the PC-10 owners seeing this thread. I haven't messed with my PC-10 dual monitor enough to yank the monitors or disconnect the board and may have done the same thing. I had no idea connectors weren't keyed on these things. Now everybody knows! Definitely taking pictures, notes, and a tape/pen to mark wires when I work on my PC-10 from now on.

Good luck getting this turned around. :)
 
The only reason i knew was i saw a thread either on here or coinopspace that talked about since the sanyo has a regular plug that this guy rebuilt his and it was quicker to just plug the monitor into the wall............... POW!!! Dead!! And they talked about how the nintendo stuff runs on 100v. Not to mention all arcade monitors use an ISO Transformer.

The specific problem was that Nintendo used standard 1960's style lamp plugs on their monitors--first they are not polarized (both sides are small meaning they fit either way), second, since they're simply a lamp plug it will plug right into ANY socket that they fit, and unfortuantely that means a lot of people forget that they had a socket in the bottom (with only 2 blades, no ground) and that it was connected directly to the 100V output of the isolation transformer. Since it looks like a lamp wire, it can easily go into an extension cord or wall outlet.

Had they used AMP/Molex or some other type of proprietary connector you would not see this problem with the Sanyo/Sharp monitors from a Nintendo cab.
 
At this point, I'm just going to Mod it. Keep it a PC-10. Just put all New everything into it as I can. 20" LCD Arcade Monitors x2, PC style power supply. Replace prity much everything with the exception of the Cabinet, CP and Marquee. Get some Reproduction Art.

It wont be stock, but it will weight a lot less and still look prity. Just tired of hunting down CRT's, which are either way to burned or well me destroying them. Only downside, is I loose the orginal arcade feel. That comes from a curved crt.
