Question about HP vs19 19" LCD Monitor

1 Answer

Screen goes black to grey

Today I recieved a monitor from a friend. It is a HP vs19e, and he said it was broken. He had recently bought a new monitor, so he figured that I would like to fix it for myself. Anyways, when I tested the monitor, it blinked from black to grey every few seconds when the Video cord was plugged in. It never shows the Bios or the usual " No signal" My problem is not that of power like many others that have used this monitor.

LCD circa 2004 (old)
what is your question,
1: is it bad, sure it,is, if it fails on 2 PCs, and cable is ok.
2: if it fails its own OSD tests its bad.
of has OSD lock the free manual tells you how to UNLOCK this feature. (the hold button trick)

3: how to fix it.? asking how to fix a LCD here?

the parts for it , inside might be found on ebay, this old.
pigs in a poke sack....
there is no schematic for it, google it ?

black to gray is my only clue here.
if the OSD is dead the black lamp is bad, or its inverter
if the back lamp is ok, then the LCD power is bad or it's logic bad or lack of power. (DC rails)

    wow even a working one for $12
    https://www.ebay.com/sch/i.html?_from=R4...



    used monitors are dirt cheap, many work.
    for $10 ,its hard to fix a bad one if a $10 monitor works, in fact old monitors are in GLUT status, now, small , square and horrible resolution, are everywhere, I have 3 in my attic now, 100% good.


    or the used ones at , GOODwill
    or the refurbs at Walmart.

    most of theses boards inside are from CHINA
    and made there, and no support docs from them
    at all.
    In the golden olden days when we made things here (usa), we had all that, with full docs, any tech could do his job , with that....
    my first job, 1965, TV shop, tech.


    today mostly not. (modules of any kind for PC)
    there are exceptions, there are web sites
    dedicated to this or reverse engineering things.

    ill show 1, i have accounts at them all.(try)

    learn to google there is no other way
    lacking a meter, a scope
    and a full schematic, only googling finds
    failures, unique to thie VS19

    all PCS , at a 2002? year i forget year now.
    had bad CAPS, the China dudes tried to clone caps, and were used in instead of real caps made in japan like the mighty Nichicon.
    and are all bad.

    the story is here, I can even name brands that are JUNK.
    this is the first thing to know about old PC stuff.

SOURCE: Power Light Blinking & Black Screen

A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

SOURCE: My HP LCD comes on when I turn on the power,but for few seconds.

The monitor has blown a capacitor, and if your good with a soldering gun and can locate the cap which will have the top rounded instead of flat, remove it and take it to the electronic store and they will give you a replacement. If the capacitor is bad it won't hold the charge and that's why you only see a second or two on the screen. Make sure you are capable of this kind of work, before you decide to do it.

Your helpful friend may have only broken something on the toner.
Have them buy you a new toner, and see if that fixes the issue.
If not, take some pictures of the inside of the printer and we'll see what we can come up with as a fix....and you'll still have that extra toner your friend bought you as compensation for their genius.

My hp vs19e monitor has dark screen and blinking power button.


Could be the power module or the backlights (more likely backlights if the "luminance" varies)- $156 sounds a little high but not insane, but you realize cost of replacement is lower, do you not?

I just had the same problem! Was afraid I needed a new video card. (--a suggestion found on another forum.) But a friend suggested a low tech solution. After turning the computer off, I opened the CPU casing and blew pressurized air inside to clear the dust out and the problem went away. Hope this helps.
