I have a Toshiba Equium A300D-16C which I am looking at for a friend. It had multiple problems, such as battery not charging, overheating, and screen flickering. I have managed to resolve the overheating (fluff in the fan & no thermal paste on the CPU) and fixed the battery charge issue with a BIOS update.
However the screen still flickers intermittently (see video Flickering Screen
), with lots of horizontal lines going up and down the screen. Sometimes this can happen straight from boot, sometimes it can happen after it’s been on for an hour or so. Pressing on the back of the screen can improve the problem, but usually it takes a shutdown and reboot then it may come back up OK, or might come back up still with the flickering lines, and take 3 or 4 reboots, or leaving it off for 15 minutes.
I’d like to try and get it fixed, and think it’s either the inverter, the LCD screen cable, or possibly the display. Before I go buying a load of unnecessary replacement parts from eBay, can anyone tell from the video posted, which it’s more likely to be, cable, inverter or screen?
