My Sony PCG-GRT170 has what I have tentatively (and definitely
non-expertly) diagnosed as a backlight problem. The symptoms:
–Everything works fine, other than the LCD. (I am typing this right
now using the computer and an external monitor).
Prior to the LCD ceasing to work, I would occasionally have
intermittent flickering. Sony online support suggested this might be
caused by the incorrect power supply, but the model number on my power
supply is correct according to their literature.
A few days before the LCD ceased working properly, I could swear I
smelled something… well not quite burning, but maybe plastic
‘cooking.’ At the time I wrote this off to an incipient brain tumor,
but I thought I would include this detail.
Suddenly, it all went dark.
The screen ‘attempts’ to light up when I change resolutions, boot up or
switch between external and main displays using the hotkey. By
‘attempts’ I mean I see a brief reddish flash along the right-hand side
of the screen.
I can still see images on the monitor (i.e. the windows XP logo as it
boots up), but they are very, dim. In a dark room, I see nothing at
all.
In my initial exploratory inquiries, the inverter came up as a probable
culprit. I ordered an inverter from sparepartswarehouse.com
(theoretically new), but installing it has not solved the problem.
a) what is my best next step?
b) what is the probability of having received a bad replacement
inverter?
c) what are some costs involved? I may well just buy a replacement
laptop if the price exceeds the cost of a new external monitor.
Thanks for any insights you may be able to provide.
