I lost my original remote control for my 42inch vizio tv a few years ago, the tv was't used for a while When I set tv up again, I couldn' get any remoe to work on the tv ,even the replacement original remote that I ordered. The ir board is the only thing I can deduce not working ... What do you think I should do ??? mod # M420SL VIZIO TV
ORIGINAL remote stopped working .I tried lots of universal remotes. Nothing worked!! bought second original remote, no luck!! can this be ir board problem and can I replace with an external ir remote through ir in put ??
I did a little background and it looks like this is the cheapest price for the board is here https://www.shopjimmy.com/vizio-3632-0172-0189-ir-sensor.htm and there are even videos on replacement. But, I was a bit put off by the TS who has, apparently, gone on to other matters. Given the shaky way he was describing how the problem started, I thought a systematic approach was a reasonable suggestion. That is, does the TV work manually? What is wrong with that check - a simple, yes the TV works manually. Same as with the response to testing the IR remote.
Oh well, my Vizio works with the remote, so I shouldn't complain.
