Hyundai 19 Hyundai N91W 19" monitor not very old screen turns on for about 5 secs then screen turns blank but power light is still on, will it be cost effective to repair?

old monitor , no PC stated, nor cable used < VGA>
test this old monitor on 2nd PC, if fails the monitor is bad.
it is 14 years old today, 2005 made
all this old are bad the toxic CCFL lamps go bad long ago.
best is the recycle center, it and buy only monitors and laptops
2010 or newer, or you get CCFL backlamps again.
the monitor this old has near zero street value, and repair costs are huge, nobody puts $1000 saddle on a $5 15 year old horse,
The CCFL panel can cost $100 and 1 to 2x that for labor
a used monitor is like $40 ,even walfart sells them called refurbs.

Call service engg.

this question is posted here 100 times, search much.
the CCFL tubes are burned out
as all do ,every 20,000 hours, 5 years old if run 10yrs a day.
all do,
until 2010 when LED BACKLAMPS HIT THE STREETS
POST 101.

Also the internal power saver must be turned off.
menu button, turn it off. on OSD

josealvajr, Check YOUTUBE again!! Use search terms: "lcd monitor repair" and "lcd monitor disassembly" and you will find some video clips that may not be for your unit, but will help you. All ccfl back-lit lcd monitors use same basic electronic design to display text and images on the lcd panel!!! Hyundai probably won't sell you a inverter/smps board. Look for swollen capacitors on the power supply board. Lots of pic's on web for you to look at. 12fixlouie

alastairhaig, Is unit 4 years old? Could be problem with units switch-mode-power-supply if same thing occurs when connected to fully functioning different pc that has all screen saver and power save features disabled. After screen goes "black" do you still see the WIN-desktop screen and icon's if you hold a bright flashlight at different angles about 1 inch from the screen? SEE = power supply in "partial shutdown" mode. NO SEE = smps in "full shutdown" mode. Do some reading in my fixya profile about "black screen of death" repairs. also read FIXYA profiles of "budmrtn" "buddymc" and other fine profiles of technicians here on fixya. You will truly be amazed when you visit YOUTUBE for video clips of owners/technicians who save their cold cathode fluorescent lamp, back-lit lcd monitors from the "trash-heap"!!! After you do your research please return here and rate this response and possibly do additional comment. 12fixlouie

Any of them in the 5vdc and 12~18vdc power supply sections.
As you can see here:

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Check the fuse on the inverter board and also verify it does have have 12vdc feeding the fuse. Worst case will be the lamps, power supply caps look OK?

Factory Setting & EEPROM Initialization Method
Factory Setting Method
- Connect the signal cable and power cable to the LCD monitor.
- Press Power switch with pressed MENU key.(Menu key + Power key).
- Then, a User can change the factory setting value in OSD menu.
- Save changed value and Turn off the power s/w.
- Turn on the power, adjust the screen.

If the screen is pinkish chances are the panel is defective.Should follow-up with Company Proview and do some correspondence.

Put a light up to the screen to see if its just the light. If you can see your background its the light or a light setting, otherwise it will need to be repaired.
