Question about Acer TravelMate 2300 Notebook
My computer monitor will sometimes come on at start but then the backlight turns off after 6 minutes. Sometimes it does not turn on at all. If I hit the ctrl and F6 keys at the same time multiple times in quick cession the backlight will come on for a short period of time. This seems to rule out the inverter.
This doesn't necessarily rule out the inverter. I've had inverters with intermittent problems that had the same effect, so having the inverter tested is the only way to rule it out. Other possibilities are a bad connection, a corroded/dirty pin or socket in a connector, a bad ribbon/cable, and a failing backlight. If it is a failing backlight, the entire screen will need replaced, as the screen is considered a sealed unit and the backlight isn't available and not considered a replaceable item. Also, it's rare, but it could have a faulty motherboard component or video card. I'm leaning towards a faulty backlight, but keep in mind the inverter and cable possibility. Start by checking and cleaning all connections.
