As the title says, I have a 6530G here (that has been recased by myself into a near-pristine 6930G casing) will power on just fine.
The issue with it is that the backlight will not come on at all. Using a flashlight, I can see the laptop booting into Windows fine, and I do have external (HDMI) output.
First off, a few specs:
AMD Turion Ultra ZM-80 2.1GHz
2GB DDR2 (667 I think)
ATI Radeon Mobility HD4650 1GB - tested fine on another Acer (model 5520G, w/ MXM slot)
Hitachi-LG GT30N
Anyways, I have tested both the display and the inverter, and checked motherboard too.
Results:
-display works fine - tested on an Acer Aspire 5536G - backlight lights up.
-tested inverter - I have the main 19V and ADJUST voltage, but no ENABLE voltage.
-tested motherboard components responsible for the ENABLE signal - all tested up fine.
-tested EACH inverter SMD component - all came up fine.
Anything else I should try? I am at a loss at what else to try.
Again, the GPU is working fine and so is the LCD itself (Samsung LTN160AT01), and the inverter seems to do its job (as I have read 19v straight from the pin on the inverter PCB) but I don't have any slight hint of the ENABLE signal on the inverter.
Other useful data:
MB model: Quanta ZK3 Rev:E
Inverter model: Sumida IV10117T/C4-E-LF
