Toshiba Laptop with flickering screen

Listed as a laptop--if a TV is a Samsung or what?

Either the cable that runs from the screen tot he motherboard is loose/broken or your video chipset on the motherboard has dry solder joints.

Flickering, always cause by LCD cable. Change it at any computer shop or service center and its not so expensive

you may have a screensaver installed and running. Turn it off

I recommend you to reinstall the display drivers of your laptop as the issue may occur due to the corrupted display drivers.

Uninstall the display drivers from Device Manager.
Expand Display devices.
Right click on the display device and select Uninstall.

On restarting the laptop, windows will detect the device and reinstall the display drivers.

You can even install the display drivers from your notebook support website:

Defective CCFL backlight may has 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.
• 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.

Go to www.lcdparts.net for parts detail and installation

Startup while tapping the F8 key,this should open the startup options screen,Select start up in VGA mode,If that works,then you need to update the video drivers

If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time

I hope this helps.

The problem is likely the inverter for the LCD screen. Do a search on laptop screen repairs and you'll find out more about it. doc...

The inverter board on your laptop is failing. It is a board that changes DC to AC voltage, and powers the backlight. It needs to be replaced.
