Question about Proview PL913B 19" Flat Panel LCD Monitor

Open Question

Once the screen saver comes on in about 10 mins, the screen goes white and the odd thing is that the blue light showing that the monitor is on is now yellow/orange showing off. so when the monitor is on and working fine the light is now showing that the monitor is off. it's almost as if the lights switched. yellow/orange is now on and blue is now off. what i do when the screen is white is hit ctrl/alt/delete and sure enough that screen pops up and i hit cancel and then i'm back on just fine..

SOURCE: Faulty monitor

This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps.

SOURCE: proview 900 series black flat panel monitor

I had the same exact problem (Blue LED blinking but the monitor doesn't turn on), but I followed the guide that delphiuser posted in this post (http://www.fixya.com/support/t127735-white_screen) and replaced some capacitors in the power supply. (I'm the guest that posted on Nov. 15) The LCD is still working perfectly today. So.. if you have some electronic and soldering experience, you could save the LCD. You do want to be careful of the high voltage capacitor in the LCD (the big one on the power supply) when you have the LCD open though, that one can give you a REALLY nasty shock.

SOURCE: Monitor goes blank less than a second after turning on.

Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

SOURCE: Monitor displays breifly then goes to blank screen

The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

SOURCE: The green light comes on then turns to yellow.

if you look at the capacitors on the boards you will find several of them that are domed or blown, these are the most likely cause of the problem. you can find replacements for any capacitor online at electronics supply stores, like radio shack but don't try them they don't supply enough different types. you can also find examples of blown capacitors by doing a search for "blown capacitor image" on any web search. unsoldering these bad caps and replacing them with identical values like 220uf (microfarradys) and say 25 v(volts). these caps have a + side and a - side the caps are marked and so is the board. hope this helps.

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did'nt.....blue power button light is still on? Everything is running but no picture.....keeps happening everytime...


this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.


if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.
as seen here

Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.

Dell screen (1901FP) won't come out of power saver mode


hold down the Fn and F8 keys, and it worked fine for me. or if your problem is you cannot wake from power saving mode (after your PC goes to sleep, then its probably just the driver for your video card). VISTA has some issues with certain drivers that the PC cannot wake from sleep
