I have an IR Detection problem on my TV and remote. Answered

I got a new/used TV from someone and the TV works great but when I use the remote like the volume works but the channels won't. Some other button controls work but some others don't. How can I check the TV IR Receiver to see if it is receiving all the IR commands?


In regards to the sending/receiving - if any commands work, all should work (assuming its the correct remote - or it's a properly programmed universal remote). This makes me think it's a problem with the circuit board, glitched programming, or the pads that contact the board need cleaning. Pop it open (look for a screw or two in the battery compartment before prying!) Check all the button pads, clean with alcohol if necessary. Replace the batteries with fresh ones just in case.

I will try that right away. It is the origanol remote that came with the tv but I will take it apart and see what happens. I thank you for your quick response and help. If this don't work do you know how to make a new universal remote learn the codes of the old one?

the new remote will come with instructions to program it. most of the time it involves 2 methods - enter the code for your make/model tv, or 'search' mode. There will be a special sequence to put the universal in 'program' mode - then you enter the code looked up in the booklet. Tada, done Search mode involves setting the remote to search, then hitting a button like 'power' repeatedly while aiming at the tv. It will try all the common codes. When the tv turns on/off then you hit 'save' and it knows what kind of tv you have. Dead simple!
