Question about Sharp 25R-S100 25" TV
If the buttons work on the tv, it sounds like the infra red receiver board has gone faulty. This is located on the bottom front of the tv behind the lens on the front. if the tv is in the prescence of a smokng environment sometimes the infra red led gets contaminated and needs cleaning. Otherwise, replace the pcb. If the buttons on the tv dont work then it may be either a connecton to the main pcb or a faulty main pcb.

This only takes about a minute and will restart 1 in 3 "Dead" Original Remote Controls.
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to
each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.
Step 5- Try the remote.
If you have a digital camera, camcorder or camera phone you can test the remote to see if it is emitting a signal. Face the remote towards the lens of the digital unit until you can see the front of the remote. Depress any button on the remote. You should see a light (steady, blink or flashing) being emitted from the remote. (no light means bad remote)
If you do then the problem might not be the remote but the sensor on the set.
IF this does not work then;
you can turn the set off and unplug for about an hour to allow any EPROMs to reset. Next plug back in and try the remote.
If this does not work it
