The Toshiba A105 notebook computer is made for mobile computer users who need optimal processing power. The LCD screen is a 15.4 diagonal widescreen with TruBright technology. The laptop has a fast hard drive access rate that is in the 3ms range for the paging and access of data. There are problems that can occur with the Satellite A105 that can be solved by knowing what to look for when troubleshooting the system.

Black Screen Problem Black screen problems can occur when the Satellite A105 backlight is burned out or the inverter is not working correctly. The backlight can be replaced with a new LCD bulb manufactured for LCD screens. The inverter is a housing unit that controls the voltage to the LCD screen. The inverter must be replaced by a compatible A105 Satellite inverter unit. Power Problems b> During the power-up phase of the laptop, the Satellite A105 will quickly turn off without signing into the Windows Operating Screen. The problem can be due to a faulty power adapter that is not supplying the right amount of voltage to the system board. You can also check to see if the unit that houses the power plug is loose, which also indicates lack of voltage or electricity going to the board for power up operations. Hardware Conflict Problems b> Hardware conflicts can cause system errors or "freezes" by loading a new hardware component into the same hardware I/O address. The Satellite A105 has designated input/output addresses for peripheral devices, such as hard drives, video drivers and other hardware functions. To solve hardware conflicts, use the Control Panel "Hardware" device function to see which hardware I/O addresses is not being used. b> Audio Not Working Correctly b> Loading a new audio program can cause the audio codec for the Satellite A105 not to produce sound. The audio codec can be restored by loading the "restore system disk" for the A105 laptop. The restore menu provides options on certain components that you want to restore. If you pick the option for audio, the program will restore the audio to its factory settings. b> On-board LAN Switch Not Working b> The Satellite A105 is automatically configured to detect T Base 10/100 Ethernet networks. If the laptop does not recognize the on-board LAN switch, check the system setup to examine if the LAN switch is on. If so, a firmware update may be needed to upgrade the BIOS.

I think not continues voltage to your inverter.Not really sure but
1.Test you power adapter that it really have continues power supply like all the time 19V..not up and down.
2.if you already change inverter then.....you should check all the
cable that goes into inverter some shoulde 18-19V ,some should have 3V..(continuesly) if problem with the voltage then its the chip that control it.

Here are some easy things that can sometimes resolve this problem:
1) Sometimes there can be a static buildup on the mother board. Power off, remove the battery, remove the power cord and hold the power button in the on position for at least 30 seconds.
2) If that didn't work- Power down, remove the battery, remove the Hard Drive and memory modules and reinsert them. Try to power back up
If these things don't work, get back to me for some more ideas.

If you've replaced the LCD Panel already, then chances are good, the failing part may be the FLR inverter. It's a thin little chip about 3 or 4 inches in length that bridges the connection between the LCD and the motherboard. It's location varies from computer to computer though, so you may have to check with manufacturer documentation. They're not too terribly expensive to replace though, much cheaper than the LCD panel, anyways.

Screen occasionally, randomly, 'blacks out' for a few seconds.


You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, 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 or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Screen flickers and then turns gray


Access BIOS and test if the flickering continues.
If not, it is a Software problem, do a full system recovery
If yes, it is a hardware issue, better contact Toshiba tech support to have your LCD repaired if you are still in warranty.

If your not in warranty, you need to check out the LCD harness that might have been loosely connected.

Hope this helps...

Sounds like the issue is a problem with the motherboard. Does it get worse when the cooling fan and/or cdrom are running?
