Monitor troubles!

[strykr]

HI all,
Turned on the videowizard today, and nothing from the monitor, which was working fine last time i turned it on (last week)

It's
getting power, there is glow from the neck, it makes the correct crt on
type sound, if i play with the dials on the monitor the sound
changes(frequency i guess) But nothing on screne. it has a Kortek chasis
aside from that i dont know anything about it. i think its a mtc9000 but
theres no label.

Im really bummed about this tbh, and fearing
the worst, but as i know nothing really about arcade monitors can anyone
suggest anything to try?

Hi dude,

Do you get any static on the screen when you power it up? And can you get a good photo of the chassis so somebody can ID it? I'm not sure how you'd have a Kortek chassis on a Hantarex monitor

What game have you got feeding the image? You mention a noise changing when you adjust the monitor so I'm wondering if the game has perhaps died and not the CRT. Have you tried another game and/or checked the game PCB is getting the proper voltage?

cheers
tim

It just sounds like a Kortek to me. And from the description of the noise that changes with frequency, I'd say there's high voltage present to so doesn't sound like a LOPT gone south. Certainly worth verifying the game.

Thanks for the replies guys! Well i took the monitor out today to have a
look at it, its an MTC9000, not sure why it came with a Kortek manual!
but like I said i know nothing about monitors!!
Here are some pics,
apologies for the quality. I was mainly looking for something obvious
but i cant see anything really. Can anyone spot anything?

Will
try a different board in it in the week, I would love it if it was that
simple. I fear the worst though, as surely a monitor should light up
even without a board in?

Was the remote adjustment PCB plugged in when the monitor was in the cab as that's missing from the pictures. Another thing is that the three rotary switches down the left hand edge of the chassis are contrast switches for the three guns (low, medium and high settings) and so should really all three be in the same position. Unless you have one of the colour guns very different strength to the rest.

The contrast switches won't prevent a picture from showing though.

At the end of the day though, can't really guess at what might be wrong with the monitor just by looking at pics of the chassis. If you don't know how to work on monitors then the chassis will need sending off to someone that does.

Hi Guddler, Yep the remote PCB was in when the monitor was in the cab, interesting about the contrast switches, the picture looked alright when it was briefly working.

I've had a couple of suggestions of things to try, just waiting on a multimeter. I appreciate that its next to impossible to help with just pictures, just wondered if anyone had an eagle eye and could spot something, or had a similiar problem ever. will try to identify any probs I can, then as you say guddler I'll have to pass it on to someone who knows stuff
