If you see a dim image on the LCD screen it means you have a backlight problem.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

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.

Why Toshiba Satellite A665 Laptop won't start?


Have you tried pressing space bar (maybe its in hibernation mode) ?

or try holding power button for a few seconds (10) then turn it back on.

as a last resort you could try take the battery out, disconnect it from the power adapter, hold down the power button for 30 seconds and then place the battery back in and the power adapter and try powering it on?

Turn it completely off by pressing the power button for 10 seconds, remove the battery (make sure it's unpluged) now put the battery back and try again, sounds like a hibernation issue and its not turning off completely. hope this helps

When I boot up the screen is all colors and lines


It sounds to me like your cable is loose to the lcd or the video card is not properly 100 percent seeded into the mother board. Prolly the cable in one way or the other, perhaps bad cable.

Turn power on..PC screen black,nothing,will not boot up


Hello,

Your first approach would be to attempt to reset the laptop by removing external power and the battery and leaving those out for a few minutes. Then, re-install the battery and add external power. Try rebooting again. It may be okay.

Since you state the machine appears not to be booting even though the screen is blank it doesn't make sense to advise you to connect an external monitor to the blue vga out plug, but you can still try that.

When all this fails you can take your machine into a repair ship where they can remove the hard drive and analyze it on another machine and see if you haven't suffered a fatal disc error that can actually recover your disc. They would also tell you if the main board has failed and give you options.

Keep this in mind if it comes to the last paragraph, the cost of repairing your older laptop may be close to the cost of a newer laptop. It is your decision to make. Don't let anyone force you into an expensive repair when you may be able to get into another decent machine, other than Toshiba of course, made by Acer.

Hope this has fixed ya.
