Question about Toshiba Televison & Video
This is due to dirty contact pads inside the remote, you can open the remote and clean the main board contacts and the keypad with some achohol.

There are no screws because it is a snap-on. To open the remote control, you will need a slotted screw driver (use a smaller one, like 3/16" x 3") to pry it open. Start prying at the bottom of the remote, near the battery compartment and then the edges. Use delicate force and try a small step at a time. Once you have pryed open the bottom end, follow the edge on the spot where it is opened and start prying the yet opened edge. Insert the blade of the screw driver the slot, grip the screw driver tight and slowly turn clockwise and counterclockwise repeatedly. Try not to separate the cover by hands. You should use the screw driver to pry open it. It took me about 5 minutes or so to open mine. After it is open, check the circuit board surface for oily residue. Try not to touch any IC component with your hands. Don't remove the circuit board, just hold the edges with your hand. There were some oily spots on the numbers' contacts, so I cleaned the circuit board contacts with a lightly damped paper towel. I also cleaned the rubber pad with a sponge and soap and dried it with paper towel before putting it back. After about 15 minutes of work, the remote control came back to life like new.

as time goes buy more of the keys will fail to work, pressing hard on the keys may do some damage to the circuit board inside. you need to remove the batteries any and small screws you can see then pry the two haves apart remove any screws that hold the circuit board to the top half and remove the circuit board to expose the bottom of the key pad you will see a black conductor painted on the bottom of each key button, use a Q-tip dipped in alcohol to clean the black conductor on all the keys then do the same thing to the contact points on the circuit board then rub a pencil eraser over the same contact points on the cicuit board and reclean with alcohol again.
This should fix the problem but it will happen again, and at some point even this won't fix the problem and logitech won't let you buy a new key pad, and that is the point I am at now and for that reason I won't buy another remote from them, I expect more than four years out of this product good luck.

This is due to poor contacts inside the remote, if the remote is old then the contact pads may be worn, if it is fairly new then you may of wasted something on the remote and the contacts needs cleaning.. If you open the remote and remove the main board and the keypad clean the tracings on the remote with some achohol also the keypad also..
