Any monitor Techs out there?

Basically, no: there are not any monitor techs out there. Manufactures support for parts or service information is non-existant on virtually all brands and models. Customer programming and diagnostic jigs that are very expensive are required for most monitors to do any kind of adjustments, upwards of $800.

Of the monitors most places are even willing to touch, 20" is about the smallest worth even taking the time to attempt a repair, and then only the name brands: Sony, Hitachi, Panasonic, Goldstar/LG, etc.

Face it, replacement of the 15" if you can still find them new is under $80US, the 17" $150US. How much time are they worth.

FYI in 99% of the cases, a low brightness picture on a el-junko brand

15" monitor has been a bad/weak picture tube.

Most cases of one color missing is the svga interconnect cable. That one should be a simple troubleshooting fix with an o'scope and some basic signal tracing of where the green is being lost.

NEC is virtually impossible to deal with on any late model equipment, they want it sent to them for repair and I have yet found a source for any service information. Plus it is a 17".
