Sounds like your LCD Control board went bad. Very small chance it is your main board since you said you cant bring up a menu.

It's only thru your remote. try fixing your remote control.
Take off the battery, open the back of your remote, lift the circuit board, clean the green painted part with cotton balls slightly damp with rubbing alcohol as well as the black thingy behind your remote pad, let it dry put it back together, replace with a new battery and try if it works.

Go into the menu and turn off Closed Caption.

Your Vertical Amp is probably Blown (bad) , but before you change that check all capacitors around the vertical amp IC and / or resolder resistors and diodes around vertical amplifier.
And NO it is NOT the Picture Tube
Good Luck

On the back of the set, look for 2 controls labeled focus and screen. If the TV is working but you cannot see the picture, try turning the screen control up little by little and the brightness should come back. If this works then make sure the focus control is set so that the picture is nice and sharp.

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
