I bought two of these monitors JoyMonkey. I didnt gather much from the ebay seller and he wasnt knowledgeable about them ,I was hoping on a sweet deal so I went ahead and bought both of the ones that were available at the time. I ended up paying $65 bucks for each shipped to me in the end.
So I get the monitors and I remove them from the packaging and the first thing I see is the vga cable dangling from the chassis. Second thing i notice before i even set it down was the power cord dangling next to it. The chassis and componets look very clean and the screen itself is clean with no burn. I didnt know how to proceed until I got some info on what i was looking at, so I started off by calling the Neotec sales & parts department to find out about these monitors. I wanted to know if they were in fact VGA monitors and they wouldnt require an isolation transformer.
I talk to the tech, very nice man. I tell him the model # i wanted info on and he was takes a pause to think and then says "oh yeah the NT-948, those will do 800X600. I then ask if there is an isolation transformer required and he stated no it is not.
So with this new info I had no problem to finally begin testing this thing. Long story short i connect my system to the vga cable and plug it in and I get nothing on monitor #1. There is a red led indicator and a faint whining sound coming from the chassis.
Neotec NT-948

Here is the red Led, what a nice picture.

So here I am about to test Monitor #2 and was hoping for a winner here, that thought was shattered after I took a closer look at the chassis and saw this busted ass cap and another one on the flyback.
Also it did not have a power cord but instead was a loose wire bundle with a molex connector.

Also this one has some writing on the tube stating it was restored in 12-02.

Id like to repair em so I have to learn about testing these chassis for bad components and get my hands dirty. Otherwise Id have to take the loss and sell em as parts and I would be kicking myself in the chunk very swiftly if that happens. So good luck on yours, I hope yours is in working order and if not than I hope you are able to work it out. Let me know after you see it first hand if you have any ideas on what I should double check on mine.
