Sound but no picture
This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

How do I troubleshoot my 1993 toshiba tv wont power pn
When it does not power up, just start checking the fuse. When you have a multimeter, you can check if the power still comes in the tv. Also go on to check if the on / of switch does work correct. But if you don't have electronic skills at all, please ask a technician, because inside the tv you can find lots of places where the high voltages can harm or even can kill you.
