Remote Sensor on TV Doesn't Work and Can't Manually Adjust Menu
I bought this TV from Craigslist for cheap. I knew the remote didn't work when I bought it, but figured I could either use the cable box remote or manually adjust the TV using the keys on the front panel.
Imagine my surprise when I find out the remote DOES work, but the TV remote sensor does not! Not only that, I cannot scroll thru the menu using the front panel buttons. Not sure why, btu they do not seem to work.
I have no idea what to do. The captions to the TV are stuck on, and I do not have a cable box yet, so who knows if I can access the menu with a cable box remote.
My dilemma: How do you remove the cover of the TV?? Is there any way to fix the buttons on the front panel so I can get to the menu? And is there any way to fix/replace a remote sensor without paying a technician hundreds in repair fees?
Oh and I am sure it isn't the remote. It programmed my DVD player just fine.

Hello Check the remote first for its infrared emission. If it is OK, the infrared sensor inside your tV is faulty. It should be replaced with same type and number. It can be located just behind the infrared window at the front panel of your Tv. You ahve to open your TV ot access it. It will have three solder terminals, and will look somehat brownish black in colour. Will look like this.
With the remote in TV mode, the input button on the remote should change the source (TV, AV1, etc. depending on the TV).
If the input button doesn't work, try a different code for your TV manufacturer. A code that controls the basic functions of the remote may not control the full set of functions of the TV. For some TVs, you can change the source from within the Menu. (It depends on the TV. I didn't notice if there was a Menu button that will open the TV menu on the RCA RCU600M.)
If none of the codes work, check if your TV has a Source or Input button on the unit. See if that button works.
If you have a different remote, please indicate the model.
Hello The remote sensor inside the circuit board of your TV is faulty. It is the component that receives the infrared signals of the remote control. If this component go faulty, no remote control will go with the TV. This component can be located on the front panel board of the TV just behind the infrared sensor window at the front. You have to open your TV to locate this component. It is a three terminal component, look brownish black in colour. The sample picture of it has attached here. It is very cheap to buy, and can be bought from most of the electronic sparepart shops at your town. If you have a concept of soldering and resoldering, you can replace this component yourself at home OK.
You can re-tune manually or purchase a universal remote. I'd recommend any kind of harmony remote. If you buy a cheap one, nobody will guarantee that it's compatible... in other words, you'll be wasting money little by little. Save yourself the heartache and buy a harmony remote... cheapest is a 525 and they work brilliantly.
Hi, remote sensor is located behind the front screen, if the remote doesn`t work as well (you didn`t say so I`m assuming it doesn`t) then you either have bad tact switches on the control board (the buttons on the front of the set) or the 5 volt line to the control board is missing, video-tek
I just realized that there is no usb port on this tv. Called tech support at vizio since I'm still under warranty. They're sending a new remote. I know it's not the remote because neither the verizon nor the vizio remote works, although the vizio remote will intermittently work if I'm one foot away from the sensor on the tv and holding the remote on a downward angle. Tech support says they will send a new remote to rule that out before they send a tech over. I'll check the posts to see if you find a solution when I finally get the tech guy out here. If not, I'll let you know what he does.
