Windows 7: LCD Controller Board

01 Sep 2013   #21

Win 7 Pro 64-bit 7601

Hmm... should have explained better that a jumper isn't a connector, the little plastic thing with metal inside is supposed to short the two metal pins it is plugged into.

It's a kind of cheap, durable and tiny hardware switch, not a connector. If the tiny thing is moved and shorts other pins the board will change things as if you flipped a switch.

It seems to control the voltage supplied to something. Probably to the screen (duh!)

From the specs sheet I linked above, your screen likes 3.3V, the backlight runs with any voltage between 7 and 20 V. Try moving the plastic thing and shorting the pins labeled as 3.3V. If it's the voltage to the backlight it will no more work, but won't suffer damage. Move it again where it was before and will work again. But I'm suspecting it's the LCD voltage.

Although the tech will likely be more useful, as long as it is free.

As for the Experia J: one of the wonders of Android devices is that you can load another (better) kind of Android OS and thus fix most of the issues that the average low-end smartphones experience from day 1. Or corruption, and get Admin rights on your phone, (rooting) to do more interesting things with it.
It's not magic and does not fix hardware issues (that are rare, admittedly), and usually voids warranty.

That's one of the new offers of the shop.
"breath new life in your old Android device", "nuke the crappy Amazon OS on your Kindle Fire HD and load Android".
I hope it catches on.
