Anyone know if one is available? If so, from whom?

With a steady hand you can DIY (ca. $20.- for parts incl. shipping), http://www.lcdparts.net/howto/troublesh ... CCFL1.aspx
or send it in to Moniserv: http://www.moniserv.com/lcdpartsnet/panelnet.htm
Quite reasonable at $75.-

EDIT: the above prices apply to CCFL, they do have LED-kits as well. http://www.lcdparts.net/LED.aspx

Moniserv and lcdparts are the same outfit.

LED? The kit does not exist for a T60.

I have one brandnew UXGA T60 LCD with this lcdparts LED strip inside.
In a few days I will post the outcome with photos.
The result is... mixed.
The work from MoniServ was, let's say suboptimal (i.e. shoddy :x ) and the hardware from lcdparts was suboptimal too (i.e. crappy :? ). I don't know what to do with this display now.
Maybe I dissassemble the whole thing and try to salvage the expensive Hyids LCD. Maybe I'll put in an LED strip from a broken 14.1" widescreen from Samsung.

The lcdparts electronics is bad design. You have to destroy the Thinkpad LCD inverter and cut it into pieces, then you have to wire the new electronics. You lose all green LED indicators. The inverter was cut in pieces at the wrong side, I wonder what kind of wannabe engineer developed this circuit, since you also cannot control the backlight. It is 100% all the time. With 400nits and more it is hard to use in the evenings. Only in full daylight it is ok.
If the engineer would have analyzed a regular inverter, he would have realized that the left part of the inverter is for LED indicators and electronics, while the right part is for the analog upvoltage converter (which is unused for LEDs). He would have cut the inverter at this location with all green LEDs remaining on the board. The lcdparts board is the size of the Thinkpad inverter and has hardly any devices on it. It could have been designed half size and would have fit nicely side by side to the original ThinkPad inverter.

And the worst part: there is no LED light diffusor in front of the LEDs, so you see every single LED as a light cone (2x mirrored by reflector) in the bottom part of the LCD.
Like back to 2005, when the first LED backlighted displays arrived on the market.

just my 2 cts.

I am also considering to swap CCFL to LED, so is it still not something to consider at this moment based on the available resources?
