my HP ze4230 laptop Trying to reboot it with a new harddrive it went black on me with no warning.I put the old harddrive back in.Its still dark but I can see in the screen very faintly with a flashlight.I hooked it up to my desktop monitor and it worked well.My problem is,I took the inverter out but how can I tell if its bad or if its the backlight that is bad..
View 5 RepliesI have a DV9000 and the LCD suddenly went dim. I thought the inverter had gone so bought and fitted one. However now when the laptop turns on for the first time I can see the display for maybe 1-5 seconds (5 on initial start, less on soft restarts), but then it goes dim again.
I have tried unplugging AC/Batt and holding power for 20 seconds but it made no difference.
I've read the sticky and many threads here but I'm confused. What is the symptons of the backlight/inverter problems?
My DV2000, when power off the monitor is dark, when power on, the monitor lit/iluminated. But nothing on the screen. The harddrive led blinks so it's accessing.
I thought it was inverter so I replaced it with the $8+ from y'allstore. It didn't work.
I accidentally dropped my Compaq Presario C571NR and it fires up Ok, but the screen is black. I have tested the video card with other monitor and it seems to work fine. I did some research and I found that it could be that either the inverter board or the backlight might have gotten damaged. I have purched a new inverter card online (awaiting arrival) to replace the existing one, but I wanted to know if any of you know which of them has the propensity to get damaged first, the inverter or the backlight?
I'm hoping is the inverter because it seems the easiest to replace, but if it's the backlight, then I'm screwed because I've read it's quite difficult to replace and it's more expensive. Compaq says they'll charge me $300 to fix it (since my warranty has already expired) but I might as well get a new one if the new inverter doesn't fix the problem.
Alright Well I bought a new inverter plugged it in and it still is doing the same thing. Only when i jiggle the wires the light goes on and i see the screen but not for long. I check for loose conncections but can't find any. The external display is fine. I'm wondering if it could be the actual bulb.

After a few minutes of warming up the line goes away and the screen looks normal. The line reappears on reboot though.
Looks like this is a problem with the backlight/inverter. The laptop is almost 4 years old, but I would like to keep it going a little while longer
I have a dell inspiron 600m laptop and my screen is dimmed out. If I turn of my laptop and restart it, the display will come on for a second ( but it is a little bit reddish) and then I hear a noise and it light goes off, and I can;t see anymore. However, I am sure the computer is still running properly
I am sure that the computer is on, and is functioning properly for two reasons:
1- if it is sunny, i can see my desktop, and what ever I have open, be that a browser, a word document, so on and so forth
2-when i connect my laptop to an external display everything is fine...
i have a sony vaio c2z - nvidia geforce 7400; x-black lcd
i have had a lot of problems with my display since august. although i didn't notice at the time, it happened soon after i installed the Win 7 RC.
when i start the laptop up the screen looks all distorted and the colours arent correct:

i assumed the screen was knackered, but i installed a game a few weeks ago and it brought the display back to life, only for it to look crap again when i restarted. this also happened when i did a clean install of vista, only for the display to go bad when the updates installed.
i have tried many times, but have been unable to replicate this...............
The bottom left part of screen has two through bolts holding the hinge to the screen on my dv5000t.
At first the screen died as I closed the screen and discovered it had broke. This pulled out the display cable, the one from the motherboard. After I plugged it back in all was fine, except my screen was half attached.
So... I took apart the screen and through bolted the hinge to the lid, just below the LCD screen. I noticed a film behind the LCD that is attached to the hinges. I also noticed grounding plates on the inverter. Is the foil part of the grounding for the inverter or screen?
I have quadrupled check the connections. The Wifi LED still works, so I figured the ground is working but I don't know if it has it's own source. I am typing from the computer right now as it is hooked up to another screen.
I think its the inverter as there is nothing on the screen but pitch black even with a flashlight. Does anyone know how much voltage is suppose to come out so I can test it with a voltmeter?
I am sure there is something I did to screw it up, but I was delicate and don't understand how the inverter could have died just like that if it was working just fine.
I replaced this board and display worked for approx. one day, now no display again, notebook still diplays fine on external monitor.
View 3 Replies View RelatedMy neighbor asked me to take a look at his zd7000. When we power it on, the screen turns on, but it stays black and displays nothing. If the laptop is hooked up to an external monitor it shows the graphics no problem on the external screen and still nothing on the LCD.
I took the the LCD apart and checked the ribbon cable to make sure it had a secure connection. That did not solve the issue.
My other idea is that the inverter is gone bad.
Do you guys think it is the inverter? Has anyone else had a similar issue?
new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...

View 3 Replies View RelatedI have a dv9700 that I have owned for over a year and recently upgraded to Windows 7 (about a month ago.) I was happy with how everything was working until suddenly today when I went to turn on my laptop it appeared the screen was dead...upon looking closer I realized that the backlight was off. I could barely make out anything on the screen but it did have an error message stating that Windows failed to boot and gave the option of repairing the system. I went through this "startup repair" utility (still no working backlight) and got my computer to boot up. Everything seems to run normally now except the backlight is still not functioning most of the time (at the moment I have the screen balanced just right so that it is on.) I had a similar problem with my screen about half a year ago but the laptop was still under warranty at the time so HP replaced the screen for free...not the case this time unfortunately I seem to remember reading that flashing the BIOS can solve a problem like this, however there is apparently no support for Windows 7 through HP Support's software and drivers page (I tried installing the latest version of winflash for my laptop...vista 64 bit but got an error message saying it was not compatible with my system)
View 3 Replies View RelatedI am having some strange problems with the backlight on my dv9700...I started a thread about this maybe 2 months ago but the backlight for whatever reason started working again and I didn't have too many issues with it until recently. Lately the backlight has only been working when it is plugged in...If I unplug it but leave the lid open it still works but as soon as I close the lid and open it again its out until I plug it back in and open and close the lid. Now I can't get the backlight to work at all except it lights up for 2 seconds or so upon closing and opening the lid. I removed the display bezel to access the display inverter and check for any loose or damaged connectors but they all appear to be fine...unplugging and plugging the display panel cable connector back in also causes the backlight to work for 2 seconds and then go out again. Besides the backlight issue the laptop seems to be working perfectly fine...can anyone help me figure this out? I should mention that I upgraded this laptop to Windows 7 right away when it was released.

My insurance will cover this so money isn't really the problem. So I was thinking about buying a backlight keyboard instead of the original black one (which works really annoying in lowlight conditions).
Now I found a thread about backlight keyboard but I'm unable to find out which backlight keyboard is compatible with my laptop. On the motherboard there is input for the keyboard-backlight. So thats not the problem.
I just got a 8730w (non-dreamcolor) and experience serious backlight bleeding. It's kind of irritating because it's obvious. Brightness set at around half only.
Does HP warranty cover this?
I have a DV9000 and just yesterday it started where the screen will go black but I can see what is going on on the screen but it is extremely faint. When I close the lid for a few seconds and open it back up it the screen appears like normal but only for about twenty seconds and then returns to the black. If I hook it up to an external monitor and I can see what is going on.
View 10 Replies View Relatedi just replaced the previously matte chi mei display on my hp compaq 8510p gb967ea (WSXGA+), with a brand new lg-philips glossy one (both certified for my notebook, of course) and for the first time ever on that notebook (ie. first time since its acquisition summer 2008) i experience backlight issues now.
just like on my very old nx9030 (which happened twice while under warranty, so its been repaired for free, and then once after the warranty period), the backlight keeps turning off by itself or when touching the lid or typing a bit heavier. so i have to close the lid and open it again to make it turn on again!
i watched out for all the cables within the frame and the one going into the inverter board, so none should be squeezed or so.
shall i open it again and look for a specific cable, jack or something like that, whether something is being squeezed?
I recently took my Compaq Presario C714NR laptop on a road trip, and one day some water spilled on the case without me realizing it, so that the case and laptop were wet when I got to my hotel room. The screen no longer illuminates - I can just barely see the proper windows and images on the screen if there is bright light in the room, but it's nearly invisible. I assume that either the backlight is dead or that a wire/connection to the backlight is loose or shorted.
Several months ago I had to replace the screen when the laptop was dropped and the screen broken (bought a new replace ment screen through eBay, replaced it myself), so the screen has had a bit of a hard life.
I'm having this problem with my Pavilion dv9700.

View 3 Replies View RelatedI have a Dell Inspiron 640m 14.1" laptop. I cleaned screen with foam and some foam flow under the screen frame, where the LCD inverter is. 1/3 of the screen (lower part) started to shudder (horizontal stripes appeared) and after some time this part stay brighter than other 2/3 upper part of the LCD. Motions on the brighter part are slow, mouse arrow movement is like in jelly. Text is hard to read. See added photo about LCD. Is it a LCD problem or inverter problem? What component needs replacement?

What could be the cause of this? Inverter or bad lcd?
I purchased a lid, bezel, and cable, too. But the cable has a blue connector that looks like it would connect to the inverter. Is there actually an inverter board that goes just below the led lcd screen? If so, does anyone know the part number?
View 7 Replies View RelatedAt first the screen was lightly flickering once in a while and it became more and more frequent. Then it started to get black, more and more black. Within 2 days it became completeley black Now it is impossible to see anything even using a flashlight it seem completely dead.
I was told by a tech that the inverter board is dead.
I took the computer apart using help I found on the net and the Inverter board is finally in my hand
I’m trying to purchase a replacement but it is confusing.
The actual number on the board is PK070007U00-A00-6AH-02995
But when I go shopping on the net I only find reference for PK070007U00-A00
My laptop is an Acer Aspire 5630-6298
What represent the rest of the numbers 6AH-02995
The inverter flaked out in my Inspiron 6000, so I ordered a new "compatible" (same part number/specs, different design) inverter, which does work, only if the LCD is outside of the chassis.
Once the LCD is placed back into the chassis, something grounds and the inverter does not work. Once I take the screen back out of the chassis, it works fine. I'm not sure what could be grounding it or causing it not to work
I need to purchase a dell D510 lcd but want to know if the inverter has to replaced with new/used lcd or can I use the old one?
