Screen flickers I have an A105 Toshiba Satellite and my screen flickers. I purchased a used complete screen that includes an inverter, black and while cables and video cable and the result is the same. The screen on my external monitor works. Do you know what could be causing my screen to flicker. I have a Toshiba A200-TJ5. The screen flickers when moving between tabs, programs, whatever. I've downloaded Windows updates but the flicker continues. What to do?

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.

If you can still view screen if you view it in an angle or spot a flashlight on screen. Then, definitely it is a problem on backlighting, might be loose connection, inverter giving up or cfl giving up.

Hope this helps

FIRST! Always remove all power! AC adapter, (Charger), and battery.

Second! Observe anti-static guidelines!

Third! This ain't tough! It just looks hard. Once you see how simple this is, I'm sure you'll agree with me.

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.

if the screen at any piont work normally its the inverter. they can be bought on ebay for 10 dollars

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

Most likely the LCD inverter. The inverter supplies the voltage to the ccfl lamps to light the display. These inverters run about $20 on e-bay.

On my toshiba M105 the problem is the Tab welds at the top of the lcd itself. 1/3 of the screen is not usable but an external screen is perfect.

the inverter maybe going bad. go to ebay get a cheap toshiba satellite a105 lcd inverter.bam the problem fix oh you would need a screw drivercause this is a diy project no need tosend it out link me if anything [email protected]
