inverter failure on laptop? backlight failure on laptop? don’t worry I will show you how to do it.
Pardon me if this is a stupid question. I had a difficult time understanding your accent in certain places. I assume that little kit you had to diagnose the problem is different depending on your laptop? I have a Toshiba Satellite. It’s pretty old, but not going to buy a new one right now. Just bought a car. I want to extend its life as long as I can.
Backlight went out the other day. When I turn it on the light comes on briefly, like for no more than 2 seconds, then goes right back out. I can faintly see images on the screen. Also, when I hold a light up to the screen I’m able to see the desktop, just like you said. I’ve been using it by hooking it up to my tv with a VGA to HDMI converter. Where would I get a kit like the one in your video for my particular laptop? Model #: PSAG8U – 053022 Any information you can give me would be appreciated.
