Having this unit L310, DATE1MMB8E0 REV:E

I had replace the following:
1. LCD panel/inverter/cable - got from a confirmed working set, (no luck)
2. Change the Intel UMA chip SLGGM, (also no luck)

and I still cannot get the display back to the LCD panel, still full white.

BTW, all the while there are display when I connect to external monitor and windows loading fine.

Hope someone here can give some indication where should I check...

This model is UMA. No discreet graphics.
Already replace the SLGGM intel UMA/Northbridge chip (as said in my first post), hence still same problem.

i think if external display is ok you should check again these all LCD.. /inverter & cable

Re: Toshiba L310, LCD display white. Need assistant pls.

usually the white screen comes (with inverter) when you unplug the cable from behind the screen.
on led when the cable its bad it does the same
but when everything its good you need to trace back from the connector and check

Check if you have LCDVCC (3.3V) on LED/LCD Panel Module (see page 19). Without 3.3v, screen will be white on you LCD panel.

Right said. In this scenario the 3.3v might be missing on the inverter.
