You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the 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.
  • 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 it up, 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.

Where can I find a schematic or instructions to open my toshiba satellite u205-s5067 laptop. I want to clean/replace my fan.


Taking apart a laptop to change the fan is a relatively simple task. Just keep track of where all the screws go and follow these steps:

1. Shutdown the laptop and remove the AC adapter. Disconnect any devices, such as a printer or external DVD-ROM or drive, that are attached to the laptop

2. Remove the laptop battery. Turn the laptop upside down, slide the battery release latch and then pull the battery out of the bay.

3. Unscrew the hard drive cover. Grab the hard drive tab and shift the hard drive to the left to unplug it. Lift the hard drive out of the bay.

4. Unscrew and remove the PCI memory cover, the optical drive cover, and switch cover.

5. Unscrew the two screws that hold the keyboard to the base, these are located in the middle of the rear panel. Flip the laptop over so it is right side up, open and remove the keyboard by using the keyboard release switches located above the keyboard. Next, unplug the Toshiba Satellite U205-S5067 Fan cable.

6. Close the laptop and turn it over so it is bottom up. Unscrew the display assembly screws located under the laptop screen hinges. Turn the laptop over so it is right side up. Open the laptop and unplug the display assembly cable and disconnect the wireless antenna from the display assembly. Unscrew the display assembly from the laptop base and remove.

7. Unplug the mouse pad cable. Turn the laptop over so the bottom side is up and unscrew the base screws which are located along all four sides of the laptop base. Gently remove the base of the laptop.

8. Turn the laptop over so it is right side up. Unplug the fan cable from the circuit board. Unscrew the screws holding the Toshiba Satellite U205-S5067 CPU fan assembly to the laptop. Lift the fan assembly out of the laptop.

9. Insert the new Toshiba Satellite U205-S5067 CPU fan assembly into the lap top. Screw the assembly unit to the lap top and plug the Toshiba Satellite U205-S5067 CPU cooling fan cable into the circuit board.

10. Reassemble the laptop by repeating the previous steps in reverse order.


Hope this helps.

Screen Flickers


Sounds like your screen is failing. Could be just a loose connector behind the screen (pressure changes the screen display), but best advice is to replace the screen.
