LED Backlight is off and Flashing Questionmark after IceTea accident?

Texte:

I bought a MacBook A1342 on eBay with a Tea-Accident in the auction description.

First I opened it up through the step-by-step Guide and cleaned it up anything inside. It was already dry, but I cleaned the sugar which remained there.

Then I reassembled it.

Now the following is happening:

After power-on through the powerbutton I can hear the startup chime. The screen keeps dark. But a short time later I can see a flashing questionmark in the middle of the screen - light from a lamp through the backside of the (apple-logo) screen.

Because of sugarremains at the lvds-connector, I presume the part on the logic board controlling the LED-Backlight could be gone defective by the IceTea.

How can I test the LED-Backlight without changing the whole display or the complete Motherboard (logic board)?

Can I measure anywhere at the lvds out? Or at a measuring point in front of the lvds out?

Or do you have a pinout of the lvds connection?

Many thanks for your Support...
