LCD screen in Toshiba Satellite M305 laptop has horizontal lines and goes blank
I have Toshiba Satellite M305 laptop for past couple of months my laptop screen is giving me problems. Sometimes my screen would have like horizontal lines and after while screen will get blank but I can still see backlight is on. If i turn it off and turn right back on it will work fine for couple of hours and it will start flickering and go back to same thing. So I don’t know if this is inverter problem or lose connection with my LCD cables.
Most likely this problem is related to the video cable. In some Satellite M305 and Satellite M305D laptops Toshiba installed defective video cables made by CMI.
It is necessary to disassemble the laptop display panel and take a look at the video cable. If the cable part numbers starts with letters CMI, replace the cable.
I really doubt that your problem is related to the inverter failure. A bad inverter board wouldn’t cause horizontal lines on the screen. Also, you said the screen goes blank but the backlight stays on, it means the inverter works properly.
If your Satellite M305/M305D laptop is still under warranty, call Toshiba and they will fix it at no charge. I’m not sure if you have to pay for out-of-warranty laptop repair. Maybe not because it’s a known issue affecting many laptops. Try calling them even if your laptop is not under warranty anymore. Please let us know if Toshiba fix it for your at no charge.

I just spoke with two Toshiba representatives. Toshiba has denied that this problem with the video cable exists and claims that customers have not been complaining about it and that they have not replaced such cables on this model. In essence they have said that it is not a known problem.

Mechelle,
I don’t know if the fixed this problem in latest M305 models but I’ve seen many of them with faulty cables.
By they way, most likely the Toshiba representative never touched a laptop in his life. He’s just a representative.
