LED T400: Retrofit a CCFL LCD will work?

#1 Post by Saucey » Fri May 16, 2014 9:37 pm

Hi everyone. So I got a T400 that has a bad LED LCD
Its not cracked but it has those 'ink blotches', also the unit I acquired doesn't have a LCD ribbon cable or the little board where the inverter will go to.
So I'd have to buy a new lid with everything on it...

I have a few R61 widescreen panels that will fit with the ccfl inverter, but will it be compatible?

Main reason why I'm doing this is that I have a few friends who'd want to buy sub $100 laptops and this route would meet that requirement.

Looking at Lenovo's support site doesn't list any differences when inputting the machine type.
6475-D68
If this has yet to be done, I don't mind risking the challenge!

Oh, if it matters I tested the bad display on a T60 and shined light behind it to see that its damaged.
Worked like a dead backlight would except missing the inverter and all that stuff.

Worst scenario is that I just sell the unit around the same price on eBay if its not possible.

The only problem would be the physical size and how it screws in. If the R61 inverter fits in place of the T400 one, it will work.

I have a spare LED screen for T400, though I probably don't meet the forum criteria (post count) to be able to sell it to you.
There are 2 types of LID, with and without space for inverter, don't remember the part numbers now, but you'll need the second one :mrgreen:

Thanks, I am going to use a screen from the R61 and the inverter with a T400 lid.
Should work fine, I mean the non-LED T61 worked, no reason why this T400 wouldnt.

I'd take your offer but I'm gotta get rid of inventory due to me moving.

Yes it will work fine. I have done the same with a T500, see here.
