SOURCE: why is there no picture but sound on my tv?
CRT (TV Screen) is probably blown. I do not suggest anyone try to open a television's casing. Even if it has been unplugged for days, it still contains enough electricity to KILL YOU. Please, the safest thing to do is to buy a new TV and it is usually cheaper than sending it to a local repair shop.
SOURCE: Our tv doesn't have sound or picture
You need a Digital to Analog converter box as your TV is analog, and all broadcasts, since Last June 12 are Digital.
SOURCE: My Insignia Flat Panel TV Model # LCD26A has no picture or sound. The screen is white
If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

You could try checking the glass buzz fuse inside of the television located on the circuit board......
If not, try using google to do a search for your model's repair guide...
I hope this helps...
