FWIW, I worked in tech support and our client used (exclusively) Gateway computers. One model was particularly prone to have inverter board failures. It took many, many calls to GW to get them to realize that swapping out the screen would not resolve the issue. Users often would receive a laptop with a new display. It would fail after a couple of months and we'd send it back to GW...again. When GW finally started fixing the inverter board, the laptops wouldn't white-screen again.
...the symptoms are similar -- white screen...on the GW units, there were a few vertical blue, green, and pink lines...I would think Nokia would have looked into that by now, but...I don't know -- it took GW about 6-8 months to listen to us.
So are you guys flashing to R&D mode when this happened or it just get like that for no reason? I'm not putting mine in R&D mode, should regular users be worried?
The first time was way after I gained root. This most recent one never went into R&D mode and the only thing major was I flashed IT2006 onto it when I first got it.
Would be nice to know if this is some faulty batch made in some period and/or in some factory. If you look under battery, where is it made? maybe the Code below WLAN an BT keys is batch number or something. Or maybe there is some date on the box. Mine is made in Germany and is one of the earliest devices sold and works fine so far (flashed many times including R&D mode switch). Can you post info about faulty ones?
I just started using a replacement 770 after the "white screen of death" and two week repair wait.
Some interesting notes,
I sent my 770 in its original box with matching mac addy serial number to Arvato in FL as directed by the website form.
My replacement was shipped from Fort Worth TX, in my originals box, I checked the numbers.
So my sending to FL was a COMPLETE WASTE OF TIME!
Nokia needs to get their act together, and fix.the screens!
I think Nokia still does not have a specific service plan for dealing with 770's.
Their service website and customer care unit only seem able to deal with cell phones.
U.S. Repair/replacement is handled here at our Fort Worth (Alliance) facility, so I'm not sure why anyone would be directed anywhere else. Obviously reverse logistics needs to be improved. We're working on it!
And not meaning to sound trite, but this device is completely new to us in every way. We're still figuring out how to handle it. Bear with us!
