Hello
There is a infrared light sensor inside the TV which detects the infrared rays emitted from the remote control, when we press each button on the remote control. If this sensor has got damaged, the set won't respond to any remote control handset. The sensor can be located just behind the infrared sensor window at the front panel of the TV. To access it, you have to open the TV. It is a three terminal component, will be soldered diretily to front panel circuit board, of with the main baord itslef. Will look somewhat brownish black in colour. There are so many types can be seen . Just look what type if fitted with your TV.
See some models infrared sensors. Check out which type your TV has.

Problem: The remote is not
performing commands properly.
• You must put the remote in the
correct mode by pressing the
corresponding component key (TV,
VCR, DVD, SAT, AUX1, AUX2) so
the remote knows which component
you want to operate.
• Make sure the component is “ready”
(e.g., DVD player has disc loaded;
VCR has tape loaded, etc.).
• You may have pressed an invalid
key for the mode the remote is in
(e.g., the RECORD key only works
in VCR Mode).
• If you are trying to turn on an RCA,
GE or PROSCAN component, press
the component key (TV, VCR, DVD,
SAT, AUX1, AUX2) instead of the
ON·OFF key.
• If you’re trying to change channels,
try pressing the OK key after
entering the channel number as this
is a requirement of certain models
and brands.
*There is a possibility that a
programmed code may only be able
to control some of your component
features (e.g., only turns a
component on and off). Follow the
steps provided for programming the
remote (See Programming sections
on pages 5–7). If the component can
be turned on and off, make sure you
press the CH+/CH- key to see if the
component responds. If not, try the
next code from the list.

Good Luck :)
