Hi guys,
This one was LD and after UC it came back to life when U7000 was replaced (there was a hole in it). The LVDS connector pins were re-soldered and remaining board checked for shorts before powering on. All clear.
NOTE: touchpad not working - left disconnected.
Now it starts, it chimes, it starts booting but after 10 seconds the FAN goes to full speed and 30 seconds later - before finishing boot up - the screen fades to black. It stays there - powered on and the fan at full speed. I
I also noticed that when you try to choose boot disk (pressing Option at chime) using keyboard arrows the change from one option to the other is REALLY slow.
I checked U5515 and surrounding resistors for corrosion and look good.
Should I try a diagnostic (I think 3S138 is the right one)? Where should I look next?
thank you dudes.
