Note: some backlight inverters will power backlights at high voltages from a lower input voltage. e.g. use caution.
Try applying power to the board. As for where to apply power and the required voltage(s)
- One way of determining this is to look at the datasheets for the ICs to work out the where to apply power.
- VCC likely goes through F1.
Datasheet for a SIMILAR IC to one found on the board (note the pinout may differ between the B and ema versions) -http://astro-foto.astronomie.cz/mp1010bem_909.pdf
Another IC: LM393 (Dual Differential Comparator)
Most laptops have the ability to control the LCD brightness. This may mean that the board needs to be told to set the backlight to a given brightness in some way. e.g. look at the datasheet for the mp1010 as may be used to control the brightness.
This looks tempting.
I might be better off with one of those boards at my current level of experience.
I figure it would be best to make a wooden frame for the whole installation to make sure not to get toasted.
As I understand the difference between the boards are the numbers of connectors. So if my board only features one connector my backlight only has on lamp, correct?
But a board with two connectors will also work?
