Hi, so i bought a notebook Lenovo T61 last year in september. The model is 6459CTO with a 15.4 WSXGA screen. This is how it shows on the packing list.
15.4 WSXGA- TFT
So 25 days after warranty expired the notebook screen died. How **bleep**ty is that ? When i turn on the notebook, i only see very dim thinkpad on the screen and then it gets completely dark. After researching, I am quite sure its either the inverter or the backlight. Since i am a college student i cant really afford getting it fixed so i have to do it myself.
Can anyone help me find the backlight ? I tried finding the backlight online but no success. Also it would be great if someone knows how to open up the notebook LCD and replace the backlight. I have all the required tools including the solder. Please help me out !!! Thanks

Welcome to the forum!
Before you start pulling that T61 apart, let's review a couple of things:
a) Does it have Intel or nVidia graphics?
b) Does it display anything on external monitor?
c) Was the LCD reddish/pinkish on initial boot before this last episode?
While it may very well be the inverter or backlight (more likely) you may also be looking at a motherboard problem. That's why I'm asking whether the machine displays on external monitor.
Replacing a backlight is NOT a job for a novice, take it from someone who's done it in the past but chooses to have it done by another party nowadays...
Good luck and let us know.

1) It has the Nvidia QuadroNVS Card
2) It works perfectly fine on the external monitor
3) When the LCD was working fine, it used to turn reddish/pink sometimes while running windows.
I have some experience with electronics i think i can pull it off. If not, I talked to a technician he said if i bring him the parts he can install them for $50. But first i need to find the backlight somewhere that matches the exact model. However, i dont know if it is the inverter or the backlight ? However, i found the inverter online, but i am unable to find the backlight. Does anyone know where to get one ?

Try eBay...make sure that it matches the LCD size.
BTW reddish/pinkish hue on the boot is a dead giveaway for a failing backlight, nothing else gives out this symptom.

I think this is the CCFL needed -
Send Moniserv an email or call them to confirm before ordering.

Also this might be useful
This will tell you how to replace the inverter

Not to offend anyone, but changing the inverter will NOT solve the problem. You most definitely need a new backlight.
Screen size does matter. Resolution does not, when buying a CCFL.
