WG D9200 ticking, then works again after a power cycle

so as I come into work today, I observe that one of our games (a Wild Riders, NAOMI 2) has a black screen. I thought the original cart I got in it might've froze, but the sounds were still playing. popping open the back door I heard the D9200 ticking pretty violently.

just on a whim though, I shut the power off, unplugged the sound and the VGA connector (to hear wtf's going on cause it's so loud in our arcade), powered on again, it ticked a few times and as soon as I plugged the VGA cable back in, the ticking stopped, it made the digital monitor hissy sound and low and behold, the monitor worked again all day.

the picture's pretty squished and jacked up looking, it definitely needs caps. but will re-capping it do away with the ticking/not powering on problem too?
 
Maybe.

First try holding the DOWN and SEL buttons on the remote down at the same time for about 5 seconds. This will access the Factory Menu. Do a Memory Recall. Then exit to the regular menu and adjust your brightness, etc if need be. See if that helps...
 
I remember reading about other people having MAJOR problems when it starts ticking like that. I don't suppose that's like a flyback or B+ issue is it?

are the D9200s as bad to work on as they're made out to be? (Korean garbage in this case :))
 
They can be very problematic, and many monitor repair places refuse to work on them. i've fixed three so far (only three I've had). One ticking monitor was a bad HOT, one was bad caps in the power supply, and one was a bad diode.

But if it started working again, try the reset i told you about. Normally it won't come back on if a part fails...
 
yeah, I don't know if it was something in the air or what because there were about like 4 games yesterday that had problems upon just being turned on. some with light fixtures that suddenly don't work, or hard drive based that wouldn't boot. maybe there truly are gremlins in that place LOL

or maybe the girl that opened up just flipped too many breakers on too fast. think that might have something to do with it, like surge-type stuff?
 
9200

Check cap on video connect board. right next to the video molex plug
Usually the esr on the cap is way off.
 
you could be right with that. it almost seemed more like it couldn't pick a video mode if anything. the cab design makes it very difficult to do any work on the monitor inside it though... back is at a slant and literally covers the entire monitor. I'm still trying to figure out how I replaced resistors and transistors on the neckboard... seriously took 10 mins just to get the neckboard back on.
 
The "clickety click" that D9200's do at startup is normal. The bad caps probably caused a shut down which is what you saw.
