Hmm. Never seen that one. At first I thought it was the same as this. But after looking closer they're different.

Search the forum a bit. You might find some info. This thread has lots of screen info too:

i suggest you test it first before modding.
Your board looks like its using XL1509, the same dc regulator as mine.
Look for the chip circled here

Desolder the positive red wire and directly connect it to PIN 2 of XL1509 chip. After this you can connect a 5v power but
NOT 12v.

If you're not sure which one is the pin2, use a multimeter to check for 5v output voltage from each pin of XL1509.

Did you test it first before modding? Just to make sure it is working.

Haha just let it fall while working on it and broke the lcd.
I orderd a new one hopefully it will be a easier motherboard this time
