sounds like the power supply "sees" a short circuit thus it switches off & then retries it again.... may be its a problem in the back lighting, are you sure its not just on standby because of a problem with dvi cable?????
would have to be taken apart........

I have a 23in + 20 in screen attached my a mac pro.
Last night the RCD tripped.

now the 20 inc screen show just a black screen - the little light at bottom RH corner flickers on and off.

I've restarted with swapped DVI port with just the 20 inc attached - but still no screen - just black.

what have I done to my screen?
