SOURCE: tv has sound but no picture
Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage. You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as the high voltage. Stargazer

Usually the blue screen is an indication that the video signal to the TV is not present. Most of the new TV's have a video input selection button on the TV and on the remote; try changing the video input selection.

You would have to try an INIT and see if it causes the tv to be operational again. It is something that you have to be walked through step by step by step and can erase the memory of the tv if done improperly. Call Sharp tomorrow morning at 9AM CST and someone can walk you through one. Call 800-237-5277 or if you have an aquos advantage model call 87-332-7867
