The location of the IR sensor on a Toshiba Regza TV can vary depending on the specific model of the TV. However, in general, the IR sensor can be found in one of the following places:
On the front of the TV: The IR sensor is often located on the front of the TV, usually near the bottom or the top of the TV.
On the side of the TV: The IR sensor may be located on the left or right side of the TV.
On the back of the TV: The IR sensor can also be located on the back of the TV, usually near the bottom or the top of the TV.
On the remote control: The IR sensor can also be located on the remote control.
To locate the IR sensor, look for a small, clear or black plastic window that receives the signals from your remote control, it could be labeled with a name like "IR" or "remote".
It is recommended to consult the TV's user manual or contact Toshiba customer service for more specific information on the location of the IR sensor on your specific model of the Regza TV.
This is a common problem with 3-year-old + Samsung 50-65 inch TV's. This advice is given with the pretext that you know how to be safe and use tools.
Locate the IR sensor on the front of the TV. Remove the stand and place it face down on a carpet. Be prepared to be able to leave it there for a few days as your replacement needs to ship. Remove all the screws from the rear panel to locate the IR or touch function/IR combo board. Carefully remove the board, get the board number that is located on the side you can not see without removing it. Since I do not know this number as there are different versions, this is a sample if what the IR board should look like. https://images-na.ssl-images-amazon.com/images/I/41wWeOocaHL.jpg
Replace it with a new one. $30 max. Put it back together and you can control your TV again.

Take the tv remote aparts,there is a screw in the battery compartment.I know this because i have a tv this model too.Take some Q tips soak it with some rubbing alchahols and clean the remote PCB board and wait like about 20 mins for it to dries.Put it back together again and with a new set of batteries.And take some cottons balls soak it with some rubbing alchahols and clean the tv set infer red light sensor on the tv set it self too by the tv LED power light indicaton.This solution should improve ur infer red senor reading like( 2-3 more m).
Please follow this procedure to find the exact problem.
Check the battery of the remote.If your battery is 1.5vdc x2,the reading should be 1.5vdc x2 also! or 1.4vdc,tolerance to response the remote.Replace the battery if it is below on the tolerance voltage.
Check the IR sensor using a digital camera or cell phone camera.
Place the camera in the front of IR sensor then push any of the button to activate the remote.If your IR sensor flashes on the camera it means you IR sensor is good if not flashes on the camera replace it.
I hope this information will be helpful.Thank you very much.
