Another LCD vs Inverter Question

I am refurbing an old Macbook 2,1 (a1181) that had a cracked LCD. Despite the crack, the machined functioned and the LCD was receiving images, albeit unreadable for the most part, but it was fine with an external monitor.

I bought a used LCD on ebay and installed it last night.

The screen lights up to a medium grey, but no graphic output goes to the new screen. External Monitor still works fine.

I've tried the video cable that was provided with the LCD and the existing video cable. I've reset the PRAM and the SMC all with no results.

My view was that the inverter, cable, logic board are fine, since it lights the cracked LCD.

The provider believes the LCD to be tested as OK, but will take a return, but asked me to replace the inverter first. I have one ordered, but I don't believe it will fix it. I tried to read all the posts on this problem and tried the ones I could try.

Any suggestions?

John Barnhill, it does not sound like the inverter. The inverters main task is to provider alternating current to the CCFL, the display itself is a function of the data lines. Check your data display connector, make sure there are no issues with that. If it still displays an image (even unreadable) I would return the LCD to the vendor and ask for a replacement. Hope this helps, good luck.

Thank you. I didn't think it was the inverter either. and the fact that the cracked one still "works" made no sense to me. it will be here Thursday and I'll know.
