    No probably another capacitor in the sweep power supply, that feeds the b+ to the vertical IC. It will have the same beginning numbers that the caps will in the vertical circuit.

No picture on toshiba 42" flat screen tv


Definitely a blown fuse, you just need to locate it.
Look up the diagram for your make and model.

TV turns on, but the red light blinks off right away and no picture. What could it be?


Hi my name is Roety,
I can help you with your issue ,
Red light blinking on a toshiba usually means bad convergence ICs and blown pico fuse.
A repairman would charge about $350 to fix it.
soldering in these ICs is not for a non technical person. 
 best of luck
