I have the same problem. Sensor doesn't work. Tried new batteries, cleaned the lens and a brand new universal remote. I took the remote to a TV repair shop to find out that the remote works. I'd have to replace the infrared receiver $75-$100. It's a Toshiba 13" with VCR, model MV13M2/W, 2002. I'd rather invest $100 in a new TV, but I'd prefer to get by with a cheaper fix. Is there possible?
Call Andrews Electronics and give the make, model number, and the circuuit board location (label printed in PCB next to IRreceiver). To check if your remote is transnmitting, point it a digital camera (cell phone camera will work just fine) and look at the screen on the camera while you press the buttons on the remote. The infrared light will appear as white on you camera display.

If no remotes work it is likely the remote receiver (ifrared and at front of set) is either dirty (lens) or bad.
A hint here is try original remote right up against the receiver--if works receiver is bad.
Note: original remote can be tested by a shop or even with most digital cameras--in a dark room the remote pointed at the camera and the lcd display will flash faintly when buttons on remote are pressed.

good day! i have read your problem, i teach some simple tips to check whether your remote control is working or not considering you have a good battery. 1st tip is buy checking it through you cellphone camera. turn on your camera and point your remote control on your camera lens the press any button on your remote. if your remot is good you could see some ligth flashing from your cellphone screen witch indicates that the infrared is working. if thereis no ligth at all the remote is deffective. if there is a ligth and still it does not work in your tv maybe the remote you have is no compatible with your unit or the sensor receiver itself of the unit is defective. i hope this will help you.
A fairly common problem with these sets is that the connections to the IR receiver inside the set degrade. Quite often all that is required is a resoldering of the pins of the receiver. This is a 3 legegd part within a small metal box located near the fron of the TV. If you have no experience with TVs, do not attempt this. I would guess that a TV shop would be willing to resolder the pins on this for not much money. Call and ask. It might be a cheap fix for you. Cleaning the lens of the remote will have no effect.
You may be spot on with your analysis. If you have a new IR receiver installed it may cost around $100 plus or minus to do so.
However, first, make sure the eye lens is not covered or dirty. Clean it off with a soft tissue to remove any oily film or other dirt or smoke. Then aim the remote very carefully with the original remote control (with good batteries; make sure) and slowly move away checking its function. If it does not operate from at least 10 feet is is substandard. (Be sure there are nothing obstructing the IR beam to reach through the IR eye).
You can get the new ir sensor from electronics shop dealing in tv parts just get the exact model number of tv.and brand name.
Clean both red filter plastic windows, 1 at the remote control end and 1 at the tvs InfraRed receiver end, with window cleaner on a soft cloth. If this doesnt work you need to confirm operation with another working remote. Either the transmitter(remote) or receiver (tv) could be faulty.
Anything obstructing the IR path to the receiver located at the bottom edge of the tv bezel?
Most likely since you dropped the remote than it stopped working, It is most likely the remote. Some universal remotes say they have the code for your television but they do not. Because lots of different manufactures make televisons under different names. Try a better universal. If it does turn out to be the piece in the television, You will probably have to have it serviced by a professional
