You have to be sure what is actually broken. Test everything you can.
My screen with inverter powered from Blutooth connector worked well for about an hour. Then it started to blink as before. I got scared that Blutooth killed the inverter. In the mean time a brand new inverter arrived and I tested it immediately. Screen still dead. I wanted to be completely sure that inverters are OK. See here is what I did:

Inverters are OK, Bluetooth power appears to be safe. New inverter is going back to the supplier. Money saved.
I did the same test but with Macbook screen connected to Philips inverter and the screen blinked once or twice and thats it. It does blink every time I power-on the inverter but after that it reminds dead no matter what I do. Conclusion: CCFL is gone after months of stutter - new LCD already ordered.
I need to do another test with Philips screen and brightness control from the Mac's logic board but I need to order a new inverter cable. The one from my sis Macbook is converted to get power from Bluetooth and I want to have both options available when new LCD arrives.
Also if others are interested in inverter voltages. Here is a video of what brightness control Pin4 voltage looks like on a fully working Macbook:

If you have a 4-wall connector you can read Pin4 voltage directly from the inverter. Just cut that yellow film protecting inverter board.
