LED Backlight is off and Flashing Questionmark after IceTea accident?
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...

Many Thanks for your help, so long.
Now I've tested the mini-display port to dvi. The port did not turn the external monitor out of the standby mode.
By inspecting the lvds cable I saw 3 defective pins at the cable. Does anyone know the exact description of the connector at the cable?
At the moment I'm stuck in a point to be hopeless.
Can somebody help me further.

Yesterday I tested the MacBook with an external DVD-Drive. I was wondering the Snow Leo Install Disc started without any Problems and the Installation finished successfully. After a reboot it started from HDD. Now I know theres something bad with the internal Superdrive.
