Lcd or inverter to substitute?

[lucapuccetti]

I recently bought an used t60. After a rest when the t60 starts up everything seems to be fine but after some minutes, let we say ten minutes, the backlit of lcd does not operates any more and I have to connect an external monitor which operates correctly. If I reboot the lcd illuminates again and everything seems to be ok again but after a while, time which is running shorter at any reboot, the backlit becomes dark again. I wonder if this may be
caused by the inverter or lcd.
Thanks for the attention

is there a pink hue?

[lucapuccetti]

Thanks for kind reply. No pink hue is visible just the image is still visible but dark. After rebooting everything is fine for few minutes, thereafter the image becomes dark again but still visible if i use an external monitor everything is fine. The time from rebooting till the screen becomes dark shortens at every reboot. If the pc rests for a day the time to the dark screen becomes longer again (5 minutes) and it runs shorter while the notebook operates .

it is most likely a LCD issue.

I agree, this does sound like your backlight is failing. To give you an idea of what to expect to spend on one, in my area I can get a good used screen in the price range of $50-80. New Lenovo parts for these are rare, but if you can find one expect to spend close to $200. There are cheap generic screens that are easy to obtain in the $100-150 price range, but quality vary widely, so I'd recommend getting an original lenovo screen, either used, or new if you can find one.

Good luck.

I would try changing the inverter first - cheaper and easier
