Having problems with your Apple Cinema HD 23" LCD Monitor ?

The upper half of my Apple 23" Cinema HD (ADC) display has suddenly become relatively dim. The power light on the lower front is now flashing the following sequence repeatedly... short-short-long. What do you you suspect has occurred? Allen Z.
