WHEN I START MY NOKIA 5130 XPRESS MUSIC PHONE . NOKIA WORD WILL BE WRITTEN AND IT GOES BLANK .WHOLE SCREEN BCOMES WHITE AND NOTHING IS DISPLAYED


There are two options because it is due to two reasons.
1st the LCD has expired for this you need to replace or get it replaced.
2nd and the priority basis method is to upgrade its firmware. Just connect it with data cable and from nokia updater, update its firmware.

Safe all the important data before doing this.

best of luck!

What's your problem?can not hook up lap top to tv


Connecting your laptop to your TV will require a HDMI cable. Attach the cable to the HDMI ports on the latop and TV, then change the source input from your TV to HDMI and your TV will now display your laptop.

My toshiba lap top 120 has a white line trough the screen


you need check
1) make sure the line is stable or changeable there when you folding the LCD lid or touch lid somewhere. there is some temp disconnection if the line changes sometimes
2) check and make sure the LCD cable and the plug/socket at motherboard and back LCD panel, they are no dirty and disconnection
3) make sure the LCD panel hardware damage (replace one) if the lind is stable there, mostly should change the LCD panel.

Display Becoming White


First, to verify if it is your display adapter, connect an external monitor to your laptop and see if it displays fine. If it is fine on the monitor, then we know that it is from your laptop screen(in this case, it is either you first check from a technician if it is the colour that has to be refilled or if you need to purchase a new screen). If not then it is from your display adapter(could be from corrupt display drivers). In this case, you would have to re-install new drivers for your display adapter(you can download it from your system manufacturer's website if you don't already have it).
Thanks

Lcm-17v8 monitor


Hi,
This is a problem with the cable that runs from your laptop to the monitor.
Or the VGA Output socket, on your laptop itself.

1:) Try using the monitor, on a different PC Or Laptop.
2:) Toggle The LCD/VGA Button on the laptop. ( This should change the display Mode )
Sometimes you Have A fn key, on the keyboard. Press fn And LCD/VGA.
3:) Check that there is no damage to the cable from laptop to Monitor.
If none of the above work, it,ll be the monitor itself. faulty panel or invertor board.

Laptop to tv!


It may be a bad cable. It may be the monitor settings on your laptop. Open Control Panel/Display and check around.
