Defenitly the screen, it wouldn't start working when you twisted it if it was anything other than the screen. Not really much you can do other than pick up another screen off ebay. It'll run you about $150-$200

You could take it into an electronics shop and ask for recommendations of what to do or even if they can fix it.

Or if you have the receipt, take it back to the retailer and ask if they can fix or replace it.

LCD screen flickering


Display Configuration A flickering screen may be caused by the computer detecting incorrect display settings as it starts or returns from sleep. It can also come from changes to the screen resolution settings caused by a new program or update installation. Verify screen resolution before assuming the issue is hardware related. Faulty Inverter Next to the display screen behind the plastic screen bezel is a small component called the inverter, which supplies power to the screen backlight. The flickering indicates the power is not reaching the backlight. To fix the issue, replace the inverter. Faulty Connectors The wires and cables traveling from the display around the hinges and into the motherboard tend to wear at the hinge area. Over time, the opening and closing of the screen causes this wear. The solution is to disassemble the plastic casing of the laptop, reorganize the cables so they have no interference from hinges, or replace the cables and connectors with new ones made specifically for the computer make and model experiencing the issue. b> Test an LCD Inverter An inverter is an electrical device on the bottom of your laptop screen. The job of the inverter is to convert DC electrical current to AC voltage to maintain power to the backlight lamp. If the display on your laptop is dark but working, odds are the inverter or the lamp are at fault. When troubleshooting monitor problems on a laptop, you may need to evaluate the inverter to determine which of the two parts is malfunctioning.

Remove the screen bezel on your laptop. The bezel is the piece of the computer casing that surrounds and protects the LCD screen. To remove the bezel, remove the screws around the screen. Bezel removal method may vary by model. Once the screws come out, the bezel should pop off. The inverter will be under the screen. Attach the positive probe (+) of a multimeter to the pin 1 on the inverter. The inverter has two connections, one on each end. With the laptop screen facing you, look at the left side of the inverter. Pin 1 is the top metal flange pointing to the right. Secure the negative probe (-) of the multimeter to any bare screw. There should be a screw securing the inverter to the laptop that will be perfect for the negative ground connection. Turn the laptop on to test the inverter. Turn the multimeter on and check the multimeter reading. If the display records voltage going to the inverter, such as 19 V DC, the inverter power supply is working. Turn the laptop off. Unplug the LCD inverter connection on the right side of the inverter. This disconnects the backlight from the inverter. Plug a working backlight to the connection on the right side of the inverter. Turn on the laptop. If the screen lights up, the backlight lamp is bad but the inverter works. If the screen remains dark, the inverter is bad.

Hello,

The problem is not from the inverter of the laptop. It is the module that is faulty, the module is like a flex in the laptop that assists in getting information from the motherboard to the screen, if it is faulty, it will start showing weird colors or start having some screen malfunctions.

Have the module replaced and the laptop will be in good condition once again. I had such experience with my HP530 and i replaced the module, trust me it worked perfectly fine.

Take care and good luck

Hi there,

ASAP (and the caps are intentional) get your laptop connected to an external monitor. If the display is fine on the "big screen", it's most likely you only have a screen inverter/lcd failure. Failing Inverters can cause the effect you're seeing as well as an LCD burn out on the way.

If the displays are identical, then your video card is about to fail.

At least you'll know, and know right away.

Best Regards,

My lcd panel not properly work .is this changable


This is most likely an inverter problem. This is kind of like the ballast in electric light. If you shine a flash light at the screen, can you see a faint image of whats displayed on the screen? If so, you have a bad inverter. You can find them on eBay for around $5. Just type the name of your computer in the search thing followed by the word inverter. Such as "Compaq dv2500 inverter". Once you have the new inverter, remove all screws from around the screen. they are usually under the rubber feet or round stickers. Once the screws are out pull the bezel off from around the screen. There are clips holding it in place, which usually come apart when you kinda twist the bezel. Looking at the bottom of the screen, you will see a long narrow board with a wire sticking out of both ends. THis is the inverter. Is you computer off? I hope so, because you can get a nasty jolt from the right side of that board if its on. From here it should be pretty easy to replace the board. Just remove the screws, pull the wires and put the new one in.

The backlight on your display is not working, which is why you can dimly see the icons. Power for the backlight comes from a small board called an inverter which is mounted in the bottom edge of the display. It is a common problem for these inverters to fail. There are replacements available from vendors online, and installing the new board is usually a simple job.

In your case, the inverter problem may be due to the hinge trouble you have. The twisting force that damaged the case may also have broken the inverter board or caused its power connection to pull loose. Or the inverter trouble could just be a separate problem. You would need to open the display to check.

There are screws through the front and the front cover snaps in place. Remove the screws and the front cover and you will see the inverter board under the display panel. There are connectors at both ends. One is the power for the inverter and the other is the connection to the backlight. Make sure they are seated and that there is no visible damage to the inverter board.

Replacement hinges may also be available for your computer. Search for them and an inverter by looking for your paticular model.

Help with Display Issues


Hi,
this appears to be a screen problem. either the cfl tubes on the way out. Or The Inverter.
The cheapest initial trial, is to replace the inverter, as this is the simplist to replace, it,s at the bottom centre of the screen, and can be accesssed by removing the screen bezel.
If you imagine the cfl tube being like a florescant bulb, and the inverter being the starter. if the inverter isn,t kicking up enough power. the bulbs not getting fully boosted up. also pink tinges can sometimes relate to inverter or cfl ( Laptop monitor tube/bulb ) if you search the internet their are tutorials, and links to these components. alternatively is to buy a replacement screen ( l.c.d panel ) however you might be looking in excess of £300 Or $600.
