My remote control gradually stopped working. It took several times of aiming it at the tv before the channel would change then eventually I got no response from the remote to the TV. I changed the batteries twice and still nothing.
I can't use the menu for set info because the remote is not responding. I can change the channel & volume and vcr will work if I manually touch the buttons on the front, however I can't access the menu in anyway because that is done through the remote control.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean. http://remotesearch.blogspot.com/

This has been answered before on FIXYA. Use the manual search code. Press "TV" (light blinks once), then press the "Up" channel button and the "up" volume button at the same time (light should come on), then hold down "Power" while aiming the remote at your TV. Hold it down until your tv powers off. Then it should be configured and working.It may take several seconds. Then check if it turns on again and if the channels are working.
this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t
you need to program your remote control. take the battaries out. and maually turn the tv on. then hit the source you want to view. for example, I want to control the tv set. I push, code search and hold it then push the source button and then release the source button and then release the code search button. now, aim at the tv and then keep pressing power button till it goes off. when the tv is off, hit return or set or something like that.( every remote has different calling for it but still the same function) it should work. try it and let me know.
I have been seeing a lot of Toshiba remote "eyes" (the infra-red receiver inside the TV) fail recently. If several known good remotes cannot control the TV then the IR receiver will have to be replaced. If you have no experience soldering and unsoldering PC boards then have a qualified tech handle it for you.
