Lost functionality w/ Universal Remote

I lost the original remote and bought a universal as a replacement. I can turn off the TV, change channels, etc., but for some reason the remote won't allow me to pull up the menu or switch from cable input to video input. I can't even find a way of switching the input from the front of the TV or in the menu. Any ideas?

Then the only way to reach your tv is through coaxial antenna port. So you can buy an rf modulator ( very cheap) and connect your red yellow and white cables (rca cables from a dvd, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me.

Sorry to have to tell you bud, there is no other way except with the original remote. Go to and enter your model and you will see what you have to spend if you want to use your tv fully! Its about %* bucks + shipping. Good luck

Re: Lost functionality w/ Universal Remote

Now, it depends upoon the Universal Remote u purchased. If your remote has the neccesary buttons - AV/TV switching,Front - Rear Input Switching, Menu, etc, it should work! Since there are multiple codes for every brand, keep feeding the various codes one by one, and checking if the neccesary functions operate. If, finally, you are unsuccesful, then, folow techman's advice. Best of Luck.

Some universal remotes control some TV functions but not all. You may have to do a code search to find another code that will work with your Toshiba TV. It may be necesary to try another universal remote or even a replacement OEM remote.

It will be best for you to buy its original remote control. Universal remotes may also work with it, but some functions may not work properly. You can buy it from the Authorised Service Center for Toshiba at your town. Just give them the exact model number of you TV set [which can be noted at its back side]. They will give you the exact original one.

RCA RCR 311B model universal remote have setup codes for Toshiba. You may also try this remote. The codes are:
1047, 1071, 1103, 1105, 1108, 1159, 1163, 1178, 1188, 1190, 1191, 1196, 1211
I strongly advice you to buy its original one. OK.

You need the original remote to change anything in the menus of the set. With a universal remote, you can manualy change the channels, but you cannot sequence them or change any of the setups to have them work automaticaly.

All TV manufactures are like this.

Call the authorized service rep, and order a new remote, or find the original if you want to be able to use your set properly. Don't accept a universal remote, because this will not properly resolve your issue.

You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If you don't have the original remote and can't find it ever or if it is too expensive you can buy an rf modulator ( very cheap) and connect your dvd player, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other cable channels are still working,

You can buy the RF Modulator from:

No input channels

Universal remote control are normally programmed for basic functions, ie. chennel up down, volume up down, numbers, etc. This is even written in the manual that they do not guarantee that all functionality can be used. Here are your options: 1. Try all the codes that match your TV, there is a slim chance that the other code have the functionality that you need. 2. Buy the original model remote control. 3. If you know of someone that have the same TV, buy a universal remote control with 'learning' function and copy the signal from the original remote control. I have the same problems before. Now I use my Casio wrist remote control to copy the special functions such as A/V so that even if the original remote control is lost, I can still use these functionality

Cant change channels

Your in the video mode so you have to change the input. On the original remote, its the button left of the power button. A universal may not work for this. If you need the original remote, Its available at Good Luck
