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...
After more reading of the schematics and the chipset datasheets, I doubt the hardware issue might be within the LCD PANEL control ICs, but not S1D13742 related. Because the logical output seems to be OK ( I can see the characters on the screen, though the pixels in the same vertical line are mess up...). It seems that the driving circuit in the LCD panel is broken...

apparently only nokia can fix this. i had wsod on my 770 and returned it to expansys after pestering them and insisting they give me a replacement. which they duly did,minus the charger complete with what looks like a secondhand battery. ok. iv'e got a 770 that works but i am dubious about if its a new one! my original 770 had a wonderful screen quality this one is a bit iffy. where did you get yours from? its still worth calling nokia and aving a go at them. trading standards say an item has to be fit for its purpose when on sale!
