The TV has sound but no picture.

Your not giving us much to start with, is this a new TV or older? Is it a CRT based TV or is it LCD or Plasma? Is this the first time you have had this problem, have you checked all the wiring connections, tried other inputs?



In general if your TV has sound but no picture it's pretty much going to need to be serviced but there are a lot of things you should check first before assuming that the TV itself is not working, more likely it's a bad wire somewhere.

The TV is a Toshiba Regza LCD 26".

I solved the problem after consulting the Owner's Manual.

I RESET THE FACTORY DEFAULTS

I pressed Menu and opened the Setup menu

I highlighted Installation

I opened the System Status menu and highlighted System Information

Press < > to scroll through the menu bar to select Factory Defaults

Enter your pin or 0000 if no PIN code has been set

Highlight Yes and press ENTER. The TV will turn off automatically after a few seconds. After the TV turns off, unplug the TV power cord and then plug it in again to complete the reset process.

The picture was back.
