SL500, LED backlight -> CCFL backlight ?

[eee3]

I want to replace my WXGA (1280x800) Matte LED to WSXGA+ (1680x1050) Matte CCFL.
But my inverter card has jack for ribbon cable (LED) and I need for another inverter card with 2 pin jack (CCFL). Am I right?
Could you tell me FRU of CCFL inverter card for SL500?

UPD. My inverter card 42W7997

Why do I want replace the LCD? WXGA (1280x800) is awful.

So, is it possible?

Maybe I was mistaken in the title of this topic. I don't want to replace the backlight of my LCD. I want to use another LCD (1680x1050, CCFL). But there is a problem - different inverter card.

You will definitely need to replace at least your inverter card in this case, consult the hardware maintenance manual for exact part nmber.

You're right. I cann't find the part number of this card in manual.
LED 1280x800 http://support.lenovo.com/en_US/product ... D=PD002490 , Inverter card 42W7997
CCFL 1680x1050 http://support.lenovo.com/en_US/product ... D=PD002650 , Inverter card 42W7997
I don't understand.

My bad, late at night... : )

There's a "LED control card" listed as 42W8219. Perhaps that's the "inverter card" for the LED-backlight screens.

The one you shown in the OP looks like 42W8219. 42W7997 looks differently if I'm not mistaken.

Cheers.

Check also the LCD cable - part numbers for CCFL are different - 44c5375 and 44c9957.

So, I have 42W8219 and I need this 42W7997 ?

Image is not very clean. Does it have slot for 2 pin jack?

My LCD cable 44c5375 (30 pin).

Seems that the cable from the inverter/control board to the screen is different...

Not sure about the cable from mainboard to the screen.

Cheers.

Edit: Anything informative in the HMM (http://download.lenovo.com/ibmdl/pub/pc ... 762_03.pdf)...? Probably start from p.203...

My T400 XWGA LED screen (LP141WX5-T​LP2, 1280x800) needs to be fixed.

But can I replace it by XWGA+ LED (1440x900)? I mean, is it also compatible and replaceable with my machine, though it is different in pixels?

I do not see why not. If your T400 already has an LED screen in it the swap with the WXGA+ LED screen should be painless and fairly easy.
