D9200 - Repaired or Not? -- UPDATE! Yes it is!
« on: February 02, 2007, 01:05:17 pm »
Been working on a 33" D9200.  Chassis was "clicking".  Interestingly, it powered up fine if the neck board was not attached to the tube.

After reading the D9200 troubleshooting guide and talking to WG Tech support (Thanks, John!) I went through the primary culprits (Q413, Q414, D424, R462, R854, & Q418) and then the secondary culprits (C413, C414, C410, & C406) and finally got the monitor to power up and display the "No Signal" message.

My question is whether or not it's fixed.  Unfortunately, the game is huge and had to stay at the customer's location.  It is a Guilty Gear XX something or other Japanese version.  I don't have anything that new in the shop at the moment to hook the monitor up to and tried to hook it up to an original Ms. Pac-Man I've got sitting here that works.

When I powered up I got no picture - not even the "No signal" message.  I unpowered the monitor and disconnected the video input signals and repowered.  Got the "No Signal" message again.  Hooked up the color and ground plug.  Scrambled video.  Hooked up sync wires.  Started getting a whine from the chassis and scrambled video changed some but stayed scrambled.  Disconnected input signals and got "No Signal" again.

Is it not possible to run original MS. Pac video on the D9200 for test purposes?  Or could there still be something else wrong with the chassis?  I'd hate to take this heavy monitor all the way to the customer's, hook it up and find out it doesn't work.

Anyone know?  I put another call into WG to see if they know but don't know if I'll hear back today and would like to take it back out before the weekend if possible.  Thanks in advance for any help.

There's one of two video connectors on the video input board to use depending on the signal you're sending the monitor. There's a cable coming from the neckboard that plugs into one or the other video connector on the input board. One connector says "VGA" and the one next to it says "CGA/EGA".

If you're using a Pacman to feed video to the monitor then that cable must be plugged into the CGA/EGA connector and you feed the video signal from the game into the white flat Molex connector on the input board.

If your using a gameboard or computer monitor pattern generator to send VGA video to the monitor then you plug that into the d sub 15 pin connector and move that neckboard cable to the "VGA" connector.

Thanks, Ken.

I had it plugged into the CGA slot and had the video signal from the Ms. Pac going to the molex connector but it didn't work.

Ended up taking the monitor back to its game and hooking it up.  The game has a 15.5K/31.5K dip switch setting.  I moved my connector to the VGA and set the dip switches for 31.5 (which the operator told me was how it was working before the monitor went down).  The picture came up looking great during the load screen (Guilty Gear XX Slash) but gave me a double image during game play.  Monitor menu showed the input signal at 15.7KHz so I shut it off and moved the dip switch to the 15.5KHz setting and the picture came up but was scrunched on the bottom and looked like crap.  I moved the settings back to 31.5KHz, got into the factory menu and did a memeory reset and game came up perfectly.  Picture looks great and game is up and running after 3 months down (but they didn't call me until two weeks ago).

Guess it's fixed.  Probably wouldn't run with the Ms. Pac because it needed a memory reset, but unfortunately you can't get into the menu until you have a stable picture.

Well, there you have it.  A D9200 repaired.  Guess I can pull that 27" D9200 sitting in the warehouse out of the corner and fix it now, since it had the same symptoms (clicking).
