Hi - yesterday my lcd screen looked like it had a score at the top, about a few cm long, but I couldn't feel any tears on the surface. However, today, there is black fuzziness all along the top (looks like leaking ink), and a huge score running from the original line all the way across the screen to the right hand side. There are also now hazy black lines near the top which weren't there before....any ideas? Is it broken beyond repair???

Re: Laptop screen damaged?
Nothing is ever broken beyond repair, but most of the time the cost of repair actually exceeds what you can purchase a new one for. And with 19" LCDs selling for around $139, you get a bigger screen and less money than it would cost to actually replace the screen on that monitor.

You can try reseating the ribbon cable on the LCD panel first, but I have a feeling you have bad T-CON board (if the T-CON board is integrated into the LCD panel, then new panel will be needed)
See example of bad LCD panel/T-CON here: http://s807.photobucket.com/albums/yy352/budm/LCD%20panel/
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 LG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
The Capacitors on the power board are usually the reason for failure of an LCD. If you open the HP VS17 ( I can provide an exhaustive step by step If I have to) remove the five screws for the power board ( larger of the two boards) and look for an area where there are 4 caps (see pic). Look for exploded, popped up, bulging, or leaking caps and replace with the same or slightly higher tolerances. The one I replaced last night were (2x )1000uf25-50volt and (2x) 470uf25-50volt. Check the rest of the board for similar issues and replace as needed.
I had the “short long short” blinking led problem with my
23′ ACD after a power outage which left my screen blank and
my cheek wet with a tear for my baby. I read somewhere that
a guy was getting a 1 volt reading on the middle pin of his
damaged 90 watt power block. I figured maybe the display might
work if I could somehow block the middle pin. So I cut a small
strip of paper wide enough to block just the middle pin and long
enough to cover both sides and it looked like a “W”. I gingerly
pressed it into the brick receptacle with a toothpick leaving
just a little slack so it would not tear when I pushed in the
small white plug. It was a bit of a tight fit but guess what.
IT WORKED… I am now enjoying my beloved monitor anew and saved
$$$ on replacement brick or repair.
If you want to try it and you feel you’ve nothing to lose, make
sure you cover just middle pin (both sides) and you may have to try a
couple of times. It worked for me, I hope you have good luck too.
The inverter board regulates the power to the LCD backlight, it doesn't affect the display, just the light.
From my experience I would say that either your LCD cable is damaged or maybe partially unplugged, or the LCD itself is damaged.
The first step would be to unplug the LCD ribbon cable and then plug it back in making sure that it is properly aligned and well seated. Does the LCD now work? If not, try getting another cable off... you know, that auction website (I don't give them free ads) and see if that works.
If it's not the cable then you can be pretty sure that it's the LCD as you have already said that it works on an external monitor so it's not the video card.
This is a problem with the cable that runs from your laptop to the monitor.
Or the VGA Output socket, on your laptop itself.
1:) Try using the monitor, on a different PC Or Laptop.
2:) Toggle The LCD/VGA Button on the laptop. ( This should change the display Mode )
Sometimes you Have A fn key, on the keyboard. Press fn And LCD/VGA.
3:) Check that there is no damage to the cable from laptop to Monitor.
If none of the above work, it,ll be the monitor itself. faulty panel or invertor board.
Hi this is the way how to
examine what's wrong with your LCD monitors. After you turned it on and the
screen blacked out, you have to check that if you can see the image on the
screen or not by shining a flashlight into the screen, not directly but find
the best angle to the screen and take a look very closely. If you can see the
icons or any image, there will be a minor problem. This is because of the lamps
inside screen. Some of them were broken and it is very easy to replace. If you
cannot see anything on the screen, there'll be some problems with inverter
board. If you have soldering tool
and want to fix it by yourself, check the caps first. It may cause this
problem. Some caps might show leaking or burn spot on the board because of too
high temp. If you don't have soldering tool, you better go get a technician to
do so. Hope this help!! If anything I
can help you with, feel free to let me know. Thank you, Tan
