Ambit Inverter pin details?

[Lifeboat_Jim]

Bashing my head against a wall trying to track down the pinouts for an old Ambit DC-AC Inverter (for the CCFL backlight on an LCD panel).

Model is a T62I244 Rev 01 (also written as T62I244.01, note it's a capital 'i' not a 1 in the middle). CN1 is a 10 pin and CN2 is a 2 pin (to the CCFL). Photo attached.

I've tried many combinations of Google and a few Datasheet archives without success (well, plenty of mention of them in Acer 'service' documentation etc, but not the required detail just at the board level). There are also several sites selling these exact Inverters as parts, alas no Datasheet alongside.

I then thought to spread the search out to other Ambit T62 Inverters in the hope they would have 10 pin CN1's but alas most have 5-7 pins so I can't even get close. I'm sure the info is out there somewhere, just a case of finding it.

Hi,
first try to identify the largest plane connected directly so connector pin - that is gonna be gnd, then the one going over the fuse is positive suply as for the others there is really no easy way to identify, but only other that should be required for it to power up is 5V ttl enable signal.

The datasheet for the controller chip is here -- http://dalincom.ru/datasheet/MP1015%20schematic.pdf
An easy way would be to try and match that up with what's on the board and buzz out (continuity check) the pins -- see where they go. That should reveal the enable and brightness-control lines. You'll probably find an R/C filter on the "brightness control" line if it's meant to be driven from a PWM input.

The inverter is from an acer C310 ,the motherboard schematic is here :

Look at page 13 for the inverter pinout.If you have the inverter cable you can test the pin connection between them.

Thanks guys, as they used to say "that will do nicely"
