Has this monitor been cap-kitted yet?

[worm]

Yes it has even on the neck board.

The flyback probably has hairline cracks or maybe pinholes in it. The flyback fail alot on this series.

everything is working fine except for it wont sinc could it be IC 201 or IC 401?

[Ken Layton]

I've only worked on a 2701 model which is an EGA resolution.

Is your sync wires connected properly and of the right polarity. The 2701 I worked on only accepts composite negative sync.

i am pretty sure thats the same monitor that i worked on in a artic thunder a few months ago,its a 25khz yes?
can you tell me the set up you have
did this monitor just go like this or have you installed a different game or changed anything?

[Ken Layton]

Here's some basic monitor information on this series:

2700 Standard (cga, 15.75 khz) resolution

2701 Medium (ega, 25 khz) resolution

2702 VGA resolution

i am sure the neotec xxx2 range are denoted by the prefixes and suffixes e.g nt2502e is a 25 inch ega and nt2502c is a 25 inch cga-i could be wrong its just thats what my neotec nt2502e manual said

Nope this series is exactly what I quoted and it's in the manual that way too. The 2702 is VGA
