My TV was working fine, but lately I noticed that sometimes it doesn't respond to remote, which didn't bother me much because I mostly just need turn it on and off because I'm using it with player only. Lately it got worse, now I hardly can get remote to work with it at all. Tested batteries on remote, programmed universal remote - problem still exists. I had similar sensor board from 42" Vizio so I tried to replace - it still the same. Right now if I'll turn it on manually, and would press volume button on remote continuously, sometimes I'm getting response, but it stops and starts responding in random. It does the same with both sensor boards. Solder joints looks OK and tested OK with continuity tester. I'm adding pics of sensor boards - only difference between them is that board from another TV had ZDR1 component and original does not. They little different in size, but that board respond to remote sometimes too, so I think they pretty much the same. Anything else I should look at?
Added pic of main board too, part where sensor connects to it.
