These have no GPU......

(L9004) i got 3.3 on pin 1 and pin 2 0,311 i try extern display from my pc and i got a question mark folder but this hdd is empty and with extern display still high fan spin

You already gave the answer. Read back your post and tell me what is wrong.

i think bad L9004?

 

[dukefawks]

Measure it and then think why L9004 could fry as it does not "just" do this. Probably a short to GND on the LCD connector side, so check for that before replacing it.

i know what happend with this board had backlight problem i replace f9700 t i put this board back in a liquid damaged Lcd cable body and f*ckt up now already 2 boards this stupid mistake
a measure pin2 of lcd connector to ground i got 35.90 k ohms ?

Check with plugged in LCD if there is a short on pin 2/3. If not then it is safe to replace L9004.
