My verizon fios remote control stop to control the 65" cinema series toshiba tv.the remote seems to be ok.The oryginal tv remote doesnt control it also.I think that there is something wron with the tv remote sensor.Had the same problem about 1 year ago.Sometimes i could program the remote and sometimes it wouldnt work.Than suddenly it started to work until now.

I can advise some basic remote troubleshooting. Try this first:
Turn off and unplug your television. Take the batteries out of the remote control that came with the television. Aim it at the remote sensor. Press and hold down the power button for 30 seconds. Press and release every button on the remote control twice. Plug the television back in and power it on. Put the batteries back in the remote control. Attempt to adjust the volume + and -. If this doesn't work try these steps.

Replace batteries in the remote control, gently with a microfiber cleaning cloth, wipe the IR sensor. You may want to lightly dampen the cloth with a light mist from a spray bottle.
Cover the ir sensor with a piece of electrical tape.
Look at your television's environment. What type of environmental interferences are there such as alarm system, other items in the room that function with remotes, (remote controlled fans, remote controlled lights, DVD/DVR/Cable Box/Satellite Box, Stereo), fluorescent lighting (includes the energy saving CFL bulbs), sunlight, smart house (sensor controlled lights and heat) or power lines by the house. Move sources (DVD/DVR/Cable Box/Satellite Box, Stereo) to another area of the room, not in the same IR path of the set.

Compact Fluorescent Light (CFL) bulbs are known to emit certain amounts of infra red radiation that can potentially interfere with electronic devices that use IR remote controls. Using CFL bulbs in sockets connected to a dimmer can result in occasional “pulsing” of light, even when the light switch is turned off. These IR pulses can be confused by the TV as IR commands and can potentially lock up the set. Use normal Incandescent bulbs
Move the TV away from CFL light sources
Try different CFL bulb brands. Professional Installers have recommended “Bright Effects” CFL bulbs available at Lowes for low amount of interference.
IR repeaters and some PC controlled IR transmitters can interfere, and should not be placed in or directed at the IR path of the set.

Lastly if possible move the set to a different room and see if you are still having the same problem.

If none of this applies then replace the ir sensor.

Yes, most likely the sensor is at fault - more precisely it's connections to the motherboard are iffy. You must take the back cover off the tv and reseat them. While you are there check their soldering points - with age they tend to melt and get loose.

Remote sensor would be located at front of tv so front panel will be removed to replace remote sensor. TV repairman will do the job for you in safe manners, novice could damage some thing while removing front panel.
Call tv repairman to get tv fixed.
Thanks.
