So ive tested for voltage at the harmess end what the monitor chassis
Plugs into when slid back
Traced the wires back to the distribution module
4 go to on off switch (assuming 2 go back)
And 2 go to monitor plug
Testing at the monitor plug it goes from a range of 0 volts to 1 volt max
Very sporadically

Im assuming this may be the issue?

Did test wrong lol
I have 240 volts at connector
Just going to test the rest and ill post results

I have continuity in the wiring to the monitor power board but
On testing the out wires i have no voltage
Is the monitor power board fixable or is it better to just get a known working one?

Hopefully have it working in a few weeks😂

Recapping it may fix it if you have the skills/tools to do it. It would probably be cheaper/easier/faster to get a 12V 4A (or better) brick style power supply, velcro it down to the monitor frame, and splice it in on the AC and DC sides.

Here's a couple of documents that may be helpful if you want to try the repair route.

Do think this would work ?

Yeah, it has enough capacity to power two monitors.

The new power supply has arrived
And has power as led on it lights up
Im just not sure which wire goes to were
On the above power unit
I have 2 white wires and 2 black ones to the main board

The two white wires should be the ground (V-) and the two black wires are +12v (V+). You can confirm it with a multimeter. The white wires should read 0 ohms between them and the monitor frame.

Well new power supply has made no difference
Still no monitor led or no no signal displayed
Im now seeing why it was left to rot😂😂

Ok. In one of your earlier posts you said there wasn't any power going to the A/D board from the power supply. Did you check to make sure power is getting to it now with the new power supply?

Just tested the plug that plugs into ad board and showing
12.09 volts from the new power supply
I do believe at some point in its life its been
In a damp area as inside the cabinet it is pitted
With rust areas
I suppose that wont of helped

Sounds like you have more than one problem. This might seem silly, but some have a power button in addition to the menu buttons, have you checked and pressed it if so?

Ukphil · « **Reply #32 on:** March 02, 2019, 12:14:16 PM »

It hasnt got a power button tilt
Do the ad boards ever get faulty or are they bulletproof
Had a feeling i bit off more than i can chew
Ill see if any computer shops local csn have a look at it👍

Thanks for your help 👍👍👍

Yeah they fail like anything else. There's a small surface mount fuse on it just above the power connector. It's labeled F1. Check that with your multimeter and see if it may have blown.

Ukphil · « **Reply #34 on:** March 02, 2019, 12:54:08 PM »

Dont suppose you have a pic of f1 fuse location do
You tilt ?
Having trouble finding it as ive left my glasses
At work😂

Phil

Tilt · « **Reply #35 on:** March 02, 2019, 01:30:02 PM »

Sure. Here ya go.

Ukphil · « **Reply #36 on:** March 03, 2019, 05:50:44 AM »

Fuse is ok tilt👍As i live in england and shipping would cost an arm and a leg for a kortek monitor
Would a decent technician over here be able to adapt a uk monitor to fit?

Well I guess it's not going to be a simple fix then. Probably something else on the A/D board has failed.

You may be able to rig something up cheaper than buying and shipping a 19" LCD from the states. I had a LCD panel that I broke trying to replace the CCFL tubes

. Turns out that same panel was used in some Dell 17" LCD monitors. I was able to pick up one pretty cheap on Ebay and took the panel out of it. You may be able to do something similar only with a 19" LCD of course. You'd no doubt have to do some engineering to mount the panel on the frame, find another location for the touchscreen controller, etc, but it could be done I'm sure.

Ukphil · « **Reply #38 on:** March 05, 2019, 05:15:44 AM »

Is the touchscreen interface serial or usb
Ive possably sourced a replacement but seller
Has asked above question

Cheers phil

Tilt · « **Reply #39 on:** March 05, 2019, 09:25:08 AM »

It's serial, but uses IGT's proprietary Netplex communications protocol. In other words you're stuck with the touchscreen & controller that it has on it.
