I have a Sharp TV model 27F-S40 and also do not have the remote. I need to access the menu to change color, sound, etc.
Can I access the menu thru the channel or volume buttons on the face of the tv?

I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

This Problem is usually caused by Leaky Capacitors in Vertical deflection circuit.
If you are handy with electronics,
Get a can of FREEZE Aerosol.
Open the Back Cover.
Put a mirror in front of TV.
Locate the Vertical Circuit.
Turn the TV on.
Spray FREEZE on top of individual Capacitor to see if it corrects the problem.
If it does, Replace that Capacitor.
