Hello ! 

Your NEC LCD 170 has circuit problem  there must be a chip getting over heated  or has a lick . 
Some chip can't handle the work load  so they shut down .
I suggest you get  a new  screen coz the cost of repair is more than buying .

good luck

Check the power cable is in securely and check the VGA cable at both ends. Wiggle each cable and see what happens. If it's OK then faulty monitor.

SOURCE: monitor won't stay on

Hey. This problem is caused by the Backlight bulb(s) blowing up.
This is fixable. You have to get into the monitor and remove the LCD screen to see what bulb you need. This is a moderately difficult job and fragile parts will easily get broken.

However by all means have a go but this is the problem that you guys have been experiencing

SOURCE: Tyris Tyris 17" LCD F179 T701DB monitor image appears for 2 secs

Tyris Model: F179
No Power
Purchased an AsIs non-Working Tyris F179 from Goodwill for $15. Opened the case, found no swollen capacitors. Tested the capacitors on the power board and found C203 680uf 16v and C202 680uf 16v only partly working. Could not find a pair of 680uf caps and since they were in paralell on the same traces I removed both of them and substituted with a single 1500uf 16v capacitor. Next, the video board does have a Novatek chip much like the Novatek chip in the Samsung 710n but look closely at the 5 and 6 legs, they are not being used in the Tyris design so the 5/6 50ohm resistor fix is not needed here. Did find C107 , C16, C50 weak, all 47uf 16v, so i replaced them. Reassembled and now have a great picture again.

i'm not an expert at anything...x'cept maybe dumpster diving. God Bless

This is the common bad capacitor problem. The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.

Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.
