switching wires screw-up or old problem got worse or both?

[TheRed]

wondering if you might be able to tell me if I just blew something or the monitor just needs a cap kit still.

Here's where I was...monitor would power on and shut off. I would turn it off and wait 20 seconds and power it on and it would work. (I might have had to do that twice, depending on how long it had been since I played the game) What I believe everyone told me was...I needed a cap kit, but it was holding enough charge to get the monitor going.

so, I swapped another monitor into the cab and all is good. The monitor that needed the cap kit was left unplugged for about 3-4 months in my parents garage up on a shelf.

on to today...I turn the monitor on and get nothing.

(THE STUPID PART!!!!!)

I swapped the pink and blue with the two red on the plug going into the monitor....just tired and irritated with all of the extra work this became today...not thinking straight...etc.. Nothing popped, or smelled, or smoked or anything. Just dead silence.

Anyways, I quickly fixed it and turned the monitor back on, again..nothing. I flip it on and off a number of times and get nothing. Not even a line on the screen or a glow in the back or anything. Even when I turn it off, wait, and turn it on again.

Everything else in the cab works...sound, game, etc...

So, here's my big questions...

Did I blow something swapping the pink and blue with the red? or did the caps that were barely keeping the monitor sort of working just go out all of the way in my folks garage?

What would swapping those wires do to a monitor?

I figured you could tell me how bad I messed things up, or if it's the old problem just getting worse? or both now or something else if I get absolutely nothing.

thanks for your time!

Oh, and it's a nanao ms8

Please explain the pink, blue and red wires.  Where are these wires located on your board?

my monitor has a single 15 pin molex plug with red, green, blue, blue w/ white, and white....which are video...

then under those on one side it is:

pink, blue, SPACE, red, red....


...well, it's a 15 pin molex with the bottom row open, making the... pink/blue/space/red/red... row of pins in the middle of the molex plug.

Well, I put the pins all in upside down....so

instead of that middle row being

pink, blue, space, red, red

it plugged in as

red, red, space blue, pink



meaning the wires for the monitor's power were switched around




hope that made any sense at all, lol.

Hmmm.... Molex connectors are usually keyed so they can't be plugged in backwards.....

I would first check the fuse(s) on the chassis to see if it blew and hope that's it.... and not the HOT (possible) or flyback (doubtful) - although the difficulty turning it on could be one of those parts failing or (more likely) cold solder joints in that circuit....

yeah, but there's nothing to protect me from me wiring it upside down. I'll check the fuse in the morning, as it's all in my folks garage. Thanks

pink and blue are ac input and the 2 reds are manual degauss switch,so if you had the red wires connected it would not do any damage,sounds like its a nanao monitor to me and probably a ms8 or ms9,and back to what i said a while back they suffer from dry solder joints,cap problems(specially the 10uf 250v on the neck),there are also 3 transistors and a double diode that cause problems-i can give you the exact position and part number next week when i return from vacation(i just need the exact model no.)
