Advertisements When my Bolt remote started eating batteries weekly I switched to another remote. I found that the codes for my TCL tv didn't work, so I resorted to the option to go thru all codes till the correct one is found. I remember doing this when I first got the TV. Is there any way to find the code that worked so I don't need to go this route again. I wrote down the codes for my AV receiver so I can get it programmed, but want to know a quick way to find the code for the tv incase I need to do this again.
