TP570 / TP570E LCD Query

[G8PSZ]

Hi, now here's the thing, I have a fully functional TP 570, which has a

cracked base plastic, so of I go & get a very reasanobly priced base

plastic of Ebay . The base plastic is OK & the bonus is that it has a

TP570E mobo attached, Upgrade time on the cheap perhaps.

Ever cautious ,I tested the mobo on an external monitor & it posts

just fine, rebuild time, job done , power on & nothing on the screen

not even a flicker, its dead. So I conected external monitor again &

all was fine , booted & ran win2k no probs, checked the obvious like

display options in BIOS set to both etc, still no joy with the integral

screen. So rebuilt again as tp 570 & all is fine. Question is have I

missed something somewhere or is it the bit on the 570E mobo that

drives the LCD dead .

I don't know if you are still messing with this thing, but sounds like the 570E motherboard must have something wrong. I swapped the lower half of a 570E onto my 570's LCD and everything worked great. So I know for certain the LCD's are compatible.

Yes, the lcd's are compatible.

Question is have I missed something somewhere or is it the bit on the 570E mobo that drives the LCD dead.

I would suspect the inverter (which drives the LCD, and fails much more often than the LCD itself). Might be worth doing some searches on inverter replacement ...
