JUST REPLEACED LCD R52 AND THE SCREEN IS BLACK


You replaced the broken LCD screen in your laptop with a new screen but it’s not working.
Does this sound like your problem? Let’s find out what could be wrong and how you can fix it.
First of all, I assume that your new LCD screen is compatible with the old one. Different screens require different video cables. Make sure you new screen is compatible with your laptop.

You did some research and purchased a compatible screen, installed it into the laptop, turned it on and… The new screen is not working!!! What could be wrong?


Before you start to panic, check all cable connections again. Check connection between the video cable, LCD screen and inverter board. Reconnect cables just in case.
Take a closer look at the connection between the video cable and LCD screen. It’s possible you accidentally pulled the video cable from the connector during the screen installation.
The video cable has to be seated properly, all the way down.
Also, on some older LCD screens there are very thin pins inside the connector. Take a look inside the connector, make sure there are no damaged (bent) pins.
You can straighten bent pins with a very small screwdriver but this procedure requires a lot of patience and concentration.

Fortunately, most newer LCDs have a different type of connector, without fragile pins inside.
OK, you have reseated all connectors and cannot see anything wrong but the new screen still is not working. What’s next?

Remove the new screen and connect the old one. If the old one works properly (except the damaged area) but the new one is dead, apparently the new screen is defective and has to be replaced.


Hopefully it has warranty.
Here’s another scenario. The new screen kinda works. You can see a very faint image but there is no backlight.
If that’s the case, disconnect the new screen from the inverter board and plug in the old screen instead, as it shown on the picture below. If the backlight inside the old screen lights up, apparently the new screen has defective backlight lamp and has to be replaced.

Camera giving invertd image.


The camera displays an inverted image on the LCD camera screen or when you view the image on windows vista? If it is Vista what program are you using to view the image? If it is the camera check the settings on the camera for the special effects settings and see if the image inversion setting is on. Ther could also be a problem with the LCD display on the camera.

To replace broken screen on acer aspire 5735


First you need to get the right screen. Take out the screen by removing the rubber bumpers on the corners of the lcd bezel, then unscrew the screws that were beneath the rubber. After that you will have to pry slightly on the edges of the bezel to unsnap it and remove it from the laptop.

After that you will remove the screws on the sides the attach the screen to the hindges. On the back of the lcd it will give the model number, ebay is a good source for lcd screens. Once you get a replacement screen, you disconnect the cable on the back of the lcd and bottom, and then repalce the screen and assemble in reverse order.

Acer aspire 5570z white screen


its either going to be a problem with the lcd, inverter or output from the motherboard probably.

Best thing to do is to try a different lcd with a different lcd cable, then if that doesn't work, then try to get a different inverter, if that doesn't work then you'll know for sure its the output coming from the motherboard.

Alot of times the LCD's go bad but the lcd cables go bad cause they are flimsy and the wires break inside.

Look on Ebay cause you can easily get these parts cheaper then most places.

Acer aspire 4720z model laptop having dim resolution of monitor


The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Try reseating the video cable/connector that connects to the motherboard first.

Lcd not working


You could have a faulty video card, or a faulty inverter, (this supplies high voltage to the CCFL lamp), or a faulty CCFL lamp.

Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a very dim image or flicking image on the LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
