Hey all!
I got one of these all in one Vaio machines for free, there was 2 stickers on the device.
NO HDD (easy fix) DONE!
LCD/Backlight problem (Hmmmmm)
So I took it home put in a 200g SATA drive and it fired up but after 2-3 minutes the screen would go blank (you can see the video feed with a flashlight) and wouldn't come back unless I power cycled the unit off and back on.
I had the back off and propped up on a box and after 2 or 3 more power cycles it stayed on long enough to install Win7 and do several updates. It wasn't till I turned it back off to put the back on that it started doing the 2-3 minute to black screen again.
I thought maybe something was grounding off on the back but there is nothing that could possibly do that. Even after I took the back back off again it would still kill the CCFL's after 2-3 minutes.
Fast Forward.
So I bought a used replacement Inverter got it in last night and power up the machine and it managed to stay on for about 10 min and then a quick flicker and POOF back to a black screen again. After a second reboot I noticed a slight CCFL flicker now.
So is it safe to assume I got a bad CCFL? I did do some testing, I pulled each CCFL plug (only 4) off the inverter and it would shut down the others in 1 min or less. I did accidently leave one plug too close to the female plug and it started to arc (whoops!) melted the plug a little but remarkably it still works like it was originally (shutting down after 3-4 minutes) I still have the original inverter board too.
I took a voltage reading off a test point and the inverter is getting a solid 19v from the mainboard with the CCFLS on and when they get shut down.
Not sure what to do next!
