4 years later... Have you finally found the solution?

I have a mid-2007 20" iMac (MA876LL) with the same symptoms. The top bulb used to flicker and but a couple of weeks ago it went out completely, and it flashes on for a second every time the computer is turned on/ woken up.

It's driving me mad, I get a headache after using the iMac even for a short time.
