Well my 770 got WSOD today ... sadly...

And I searched from internet and understood that it was due to the LCD controler... I doubt if Nokia will satisfy me to have my tablet fixed. So i am wondering whether i can fix it by DIY ( I learned EE ...)

The LCD controller from Epson is S1D13742... and there is one power regular chipset (TK63115) to power the LCD controller. I am wondering if the LCD controller itself got broken, or just the power regular chipset? If just the power regular chipset broken, I would be happy... but if the problem is in the LCD controller, I have no idea where can I buy this, and if it will cost me too much to buy it...

Anybody knows the answer? If I have no confidence to fix it, I would not go on to open the cover of the 770 as I still have a little hope to get it fix by Nokia support...
