Acer :: Inverter Board
Nov 17, 2009
At 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 computer turns on and I see the same image (sort of distorted) about 6 times
What could be the cause of this? Inverter or bad lcd?

My daughters Acer 3680 just stopped working. I purchased a new AC adapter and it still doesnt turn on. The battery is new. Im guessing its the power jack that needs replaced. To avoid soldering Ill purchase the whole DC/USB board
[url]
I need step by step instructions on how to dissasemble the notebook. I got it mostly apart but i just can seem to separate the thing in half to access the DC/USB board. Any online resources, videos, manuals that would show this process of dissasembly?
I found a post on here with the identical problem. The post pointed to a Utube video that showed the process...that video has since been removed....heres the old post

i got the New DC/USB power board today and installed it. Put everything back together and its still Dead. Could something else have been damaged. The old DC/USB board smelled burnt and it had a little smoke coming out by the board. Which led me to believe it had a short and burned up. Now I dont know what do do. Any suggestions to trouble shoot this? I allready got a now AC charger and battery so i know thats not it.

I 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?

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?

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 have a Dell 17" laptop and the screen shows this blueish green vertical on startup.
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

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 just purchased a led screen for my xps m1530 that came with regular ccfl 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?

I 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.

My 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?

I am looking for a reliable car power inverter for my 2007 Macbook Pro. My car has 2 power outlets (12V / 120W). I know there is a 15A fuse, so the maximum it can handle is 180W, but of course I do not want to take that risk and stay around the recommended 120W. Because of this, it limits the number of choices I have concerning power inverters. I have seen one from Duracell called the Pocket Inverter 100. Here are the specifications:
AC Output Power (Max Continuous): 80W
AC Output Power (Peak): 100W
AC Output Surge Capacity (Peak): 160W
AC Output Voltage (Nominal): 120V
AC Output Waveform: Modified Sine Wave
So, this leads to a few questions:
(1) The MBP Magsafe Adapter requires 85W. However, this inverter can provide only 80W of maximum continuous power. Will this be sufficient to charge and run the MBP in the car?
(2) I searched around and read a few posts by others regarding pure sine wave and how it is important to have it running to laptops. Now, this inverter has an output of a Modified Sine Wave. Will this be fine and will the Magsafe adapter be able to handle this?
(3) recommendations for car power inverters within these specifications?

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'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.

I plug in my adapter and it turns on and all is well once I put it in the charging port to charge the battery of my computer the adapter shuts off immediately. The charging port on the computer is slightly cracked from a fall about a year ago but it recharged perfectly fine until now. I've had 2 other adapters go out on me the original and an aftermarket and now this one is acting up on me. After a bajillion trys if I get the charging prong at the exact right spot it'll charge the battery if I push it in too far it shuts off etc.... Is this a circuitry connection problem? Does it have something to do with the cracked charging port? Is it an electrical short? Is it another bad adapter? Is it a bad battery? Is it a bad "charging board"? Which of these is most likely the case?

My screen went black. Did some research and found it it was most likely the inverter.
I replaced the inverter but it still flickers and then goes black while its booting up.
How can I tell if this is the back light or if this is the lcd itself? I've heard the backlight is hard to replace and I might have to take it somewhere to have it done which would cost $$ .....

I have a problem with my E1405 with its lcd backlight turned off about 1 second after opening the lid.
I can still see Windows running when I look really closely.
According to what I've read it's most probably a faulty inverter. So I bought a replacement off eBay and installed it

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.

but when i take screencaps and connect it to another monitor everything looks fine.

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...............
