    Do you mean NEW external monitor cable or New LCD screen panel cable, which must plug in motherboard of inside laptop; That's totally different, for the external cable you can plug it by your self, but for the internal LCD pane cable, you can't DIY.

The plug on the screen ribbon cable which connects to the motherboard has dry solder joints. Closing the screen and typing hard on the keyboard can break these joints very easily. All you need to do is re-solder the joints. This is a very delicate job and requires a lot of patience.

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.

hope this helps

Laptop screen flickering diffrent colours

Hook a spare monitor to the video ouput usually on the back, if picture okay! the problem is the new LCD screen or video cable which you replaced, if both show the same symptom it is the video graphics card normally built into the motherboard.

I start samsung v20 up and all I get is a blank screen. I can hear sound. Please can anyone help


This problem could be caused by a number of issues.

First of all you will have to trouble shoot the GPU (graphics processing unit). To do this you will need to hook up an external monitor to the laptop and use the keyboard to switch from the laptop screen to the external monitor. If you can see the information on the screen then there is nothing wrong with GPU.

If that is the case then you need to be looking at the cables that lead from the laptop motherboard to the inverter and also the ribbon cable that runs up behind the the screen itself. This means you will have to disassemble the laptop.

If the laptop is still under any warranty then i recommend that you arrange to send the laptop in to Asus as disassembling the laptop will certainly void the warranty.

If the laptop has run out of warranty and you are prepared to have a go at it yourself then click on the link that i have provided below for a short guide with pictures explaining what i have told you regarding the cables >>>>>>>

Please note that if you feel that your unable to check the cables or disassemble the laptop then i recommend that you take the laptop to a reputable PC repair store and have them check on the cables and the LCD screen itself.

Good luck and please post back if you require anymore assistance.

Blinking toshiba satellite A 05-54547 problem

A blinking monitor just might be a loose connection of the main display cable that runs up the left side of the display and connects to the motherboard. Also check the two wire cable attaching the inverter to the screen. The bezel of the screen will have to be removed as well as the power strip and keyboard to check the display cable. Remove the lcd screen from its hinges and look behind the display, there is a flat cable that plugs into the top edge of the screen. This cable has a habit of getting loose and falling out of the socket.

Now there is a chance that the BIOS of the laptop needs to be updated. There are many instances where the display starts acting up and a BIOS update is the correct action to take. Go to the Toshiba support site, put in the model number and then put in your operating system. Scroll down to where the BIOS is listed under downloads/drivers. Download and install the new BIOS, reboot.

I opened my samsung v20 laptop and now my mouse pad dont work. There is a cable loose but i dont no where it goes.

hello.. You have to put the ribbon cable back on to the mouse pad. there will be a socket under the deck lid where you need to reconnect the ribbon cable. there might be 2 little tabs on each side of the socket if there is, pull the tabs away from the socket carefully, slide the cable in the slot, and then slide the tabs back. that will lock the ribbon cable in. be careful. those sockets can get damaged easily. good luck !

Screen Keeps dimming and contrast function does not work

This is possibly, a loose cable or the screens inverter board is overheating. the inverter is similar to a booster in a flourescant light fitting. which converts power from DC To AC and boosts up the panels Light Tube. CFL if it,s faulty or overheating. this will cause the panel to dim.
also check the plunger at the underside of the screen, isn,t sticking down. designed to cut off the panel when the lid is closed. Finally some model laptops, only boost the brightness running on A/C Power. the battery would run-out fast with screen at full brightness. if theres an fn key on the keyboard, press fn and the brightness button to adjust screen brightness.
