The CRT stants for Cathode Ray Tube. In an old fashioned tube tybe TV the entire tube is the CRT. In a rear projection TV like yours there is a smaller CRT tube in the rear of your TV. A series of lenses and lights magnify the picture and project it onto the large screen of your TV, similar to a movie theatre projector but in reverse. Actually in a TV like your it may have three CRTs one for each primary color of Red, Green, and Blue.

If you can source out a replacement CRT or CRTs it may be worth replacing as I'm sure this is a nice set considering it's size. But, if you were considering moving into the world of HD you may want to get a new set. I looked on the net and couldn't find a replacement CRT.

Crt stands for cathode ray tube. These most generally will be replaced versus repaired. You are the only one that can say whether or not it's worth it, it's a good tv with good reviews and should last a good amount of time before further repair, I would say it's just going to boil down to costs.

    Also, keep in mind that as of next year everything is going digital. This may be the perfect oppertunity to upgrade.

projection TV`s have many protective circuits in them, they protect your CRT`s from damage, over voltage called x-ray, and many others, you need to have it checked before the damage is more costly your TV is not happy and needs to be checked

Hitachi 60SBX78B No sound or Video


replace pico fuse E994 and capacitor C707. You have to disconect alot of wires and remove the screws holding the boards. you DON'T have to remove the large high voltage wires. You have to stand the board on it"s edge to unsolder the components from the back side of board. Good luck it worked fine for me. fcs0998@aol.com gene

Hi there...


If the symptom is no sound,no pix--blinking LED, then C702 102K/2KV capacitor shorted and E994 pico fuse open might be problem. If so, consider replacing cap w/ 3KV for improved reliability.
