You may have gotten a bad board. this board is the most common failure to the back lights lighting. the cffl's can not be replaced they are a part of the panel, you would have to completely dismantal the panel to get to them. if you feel that the board is good the next step is the main board. the feed back to the main board is not being excepted the processor, replace the main board.

Dell Inspiron 1526 LCD inverter unable to turn on lamp error message in diagnostics. PC boots up to login user screen and then goes black with the exception of the mouse prompt. It is visible moving...

Go on ebay and buy a new inverter for less than $10. Go on youtube to see how to replace the dell inspiron 1526 lcd inverter or the dell inspiron 1526 lcd screen. I put the lcd screen on because sometimes the problem might be your screen. If things don't work after installing the new inverter board, then buy a new lcd screen off ebay. The inverter board and screen are easy to install. Just go on to find a video that walks you through it. The inverter sits at the bottom of the lcd screen. Some are screwed on, some are welded onto the screen, some are held by a small piece of tape. Even if you have to pry the old one off, just put the new on on held by a small piece of tape.

Dell W1700 HDTV ready problem

I had the exact same problem. Another thread on this site recommended replacing the inverter from

I ordered the replacement inverter from their San Francisco office this past Friday. I received in less than 72 hours later and I live in Tampa. AND THIS IS THE HOLIDAYS.

Anyway, they have a tutorial installation instruction on their website for the Dell W1700. I have never worked on a tv, but with their tutorial it took me about an 1.5 hours to disconnect, disassemble, repair, and test the tv. Everything now works again... and for only $90 including shipping.
