Thanks for looking at this thread - I'm desperately trying to solve a problem so my 10 year old girl can continue getting her Minecraft fix on an old laptop.
The Acer Aspire 1691 WLMI laptop in question has been having deteriorating screen image for some time, and the LCD finally stopped working. It does show the backlit image when the brightness is lowered and when I spam the Fn + F6 key. I know the LCD panel is OK because in bright sunlight I can see the image on the screen. Of course, it could be the backlight bulb.
Anway, I read that it could likely be the inverter and as that is a cheap and easy fix (to just swap it out) I bought a new one and fitted it. Nothing. It doesn't even allow me to do the Fn + F6 thing.
I got it swapped out for another new one and same thing. Just black screen - when I put the original one back in, I can still use the screen intermittently by lowering the brightness and Fn + F6.
So my question is: is it possible that the new inverters I have fitted are working and that my problem lies elsewhere (perhaps the backlight bulb) ? I ask because the vendor said that the fact that my screen doesn't work after fitting them means that my problem isn't with the inverter. I don't understand how fitting a new working inverter yields the result that my screen performs worse than with my old inverter - at least I could get something from the screen before. BUT, perhaps I am missing something - I don't really understand electronics and I thought someone who knows these "repair level components" might be able to tell me whether this is a possibility.
My primary aim is to ascertain whether I can rule out the inverter as a possible problem. I'm not trying to ascertain whether the vendor is right or wrong although I suspect they have supplied me with unworking or incompatible parts.
I'm trying to avoid changing the backlight bulb as I feel its too fiddly and the bulb is more expensive than the inverter so I may as well just go to replacing the LCD panel next. But I'm still hoping that changing the inverter will work.
Thanks in advance
