Answers :

I'm going through the same thing with a Dell 1905FP - it has 3 bulging capacitors on the Power Supply/Inverter board, and I suspect they are the culprits. At first it delayed a few seconds to start (green power light flashing in all situation), then it took about 10 minutes, then delayed about 45 minutes, then went all the way to about 6 hours - all within a week. When it did come up after the delay, it was perfect. Now it won't come up at all....

It's out of warranty, Dell will have nothing to do with replacing this common failing board, and the replacement board is $50 from an online LCD repair shop.

I'm trying the capacitor replacement tomorrow - they're about 25 cents each... it's worth a try.
