20 Most Recent Hyundai Electronics ImageQuest N71S 17" LCD Monitor Questions & Answers

If it does the same when attached to another PC, then please read below.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

When you have white glow and no pictures, then more likely the the LCD T-CON board (part of LCD panel assembly) is not getting 5vdc feeding it, it can be blown fuse on the T-CON board or the logic board is not feeding the 5vdc to the T-CON board.
You need to check the power supply and the logic board first for bad caps (leaking/bulging top).

peter_chadwi, You forgot to mention date of manufacture from the rear cover of monitor??? If unit is out of warranty period you or qualified technician will need to investigate the units switch-mode-power-supply for proper dc voltage output. +5 v or 3.3 v and +12v Whenever strange or weird things start to occur with a cold-cathode-fluorescent-lamp back-lit lcd monitor, I would suspect the culprit to be the SMPS/inverter circuit. Hyundai lcd units have 3 year warranty. Verify that monitor does same at different "known-good" pc!! If unit still has inaccessible "menu" then start warranty service processing. Don't let Hyundai off the hook!

Send me good clear picture of the Power supply/Inverter baord and the logic board (the board with ribbon cable attached to the LCD panel and the logic board), my email is [email protected]

First of all, the screen glows white means that the inverter circuits are working and the power supply for the inverter is OK (12~18VDC is used for the inverter circuits), 5vdc for logic is more likely to be OK since you can turn it on or off. There isno way any peson can tell for sure hat it is not blown fuse or bad transistor unless he can actually make some voltage testing first. Do you have test equipment and basic knowledge of electronics? Picture will help. You can also see what usually goes bad in the monitors, http://s807.photobucket.com/home/budm/allalbums

not transistor, but it's capacitor problem. It's happen almost to all kind of LCD monitor and TV, just click here to solve your problem.

The screen has white glow and no images means that the LCD controller board (part of the LCD panel) is not getting the 5vdc power feeding it from the logic board through the ribbon cable, it is either the cable came lose or dirty contacts, or failed 5V switching transistor for the LCD controller is bad, or blown fuse on the LCD controller board. See pictures here: http://s807.photobucket.com/home/budm/allalbums

Look at the LCD panel album.

This monitor is sensing information from your computer regarding the configuration. The computer is trying to do the same thing. First, boot the computer in safe mode. This will set the output of the computer to VGA specs. The monitor should work with this spec. If not, then check your connections and try to reset the monitor to factory specs.

This monitor has only a limited number of resolutions and refresh frequencies that it supports. Be sure that your computer is configured to one of these standards.

Beyond that, try on another system, if possible. If it works there, it could be your video card is not compatible with the monitor/monitor not compatible with video card. I had someone give me one of these and it works perfectly. I tried other resolutions and the problem with it shutting down shows up.

Solution: run 1024 x 768 at first, then try to switch to 1280 x 1024.

purchasin757, What type monitor? If lcd type, may have 1 cold solder joint of some component lead on the "switch-mode-power-supply / inverter ballast circuit board, that goes "open" (intermittant) after it reaches a certain unspecified temperature/time period. Unit will need to be investigated by you or electronics technician to find common problem related to all brands of CCFL back-lit LCD monitors. How old did yu say your unit is??? May be that it also need some new electrolytic filter capacitors to be installed on the SMPS/ inverter board to make it servicable for 2 to 4 more years. Lots of video clips you should investigate at YOUTUBE before you return to fixya to do a customer reply and rating of this response to your post. You will also want to do a lot of readng in the fixya profiles of "budmrtn" "12fixlouie" for more info on this (your "black screen of death" symptom) common problem that affects not hundreds, but many thousands of lcd monitors. Let us know what you will do, after you research problem. 12fixlouie

It should be an option when you click save.
I have no knowledge of this product, but you could open in word and save as a doc file.
If you have word 2003 or earlier, you can download a free file to enable word 2003 to open docx files.

Those are a total hassle. Try updating windows first until its current. If you added ram lately, make sure you got the right stuff. I had that problem after I added ram, but it was proper ram. I eventually found I had a bad hard drive with errors, so I made a windows 10 image on usb, replaced the drive with a $50 western digital on Amazon in under an hour delivered. Reinstalled windows. Blue screen of ***** gone forever.
