My Tv says Keys locked LG 42inch

Why dont you purchase a universal audio remote control from your local audio and TV store or use a Anroid mobile phone and download a universal TV remote APP

Your Main board is defective. Your board from Shop Jimmy is $69.00 but they are out of stock.EBR65469804 is the part number.

Try jammed keys on the remote control best if you take battery out the remote and operate manually and see what happens

You need to find how to CLEAR the auto channel settings. Sounds like the TV is set to SKIP all channels. Look for a MENU and then look for an AUTO setting that will walk through all channels and set those where you have reception as the "list" that the remote and the Up/Down buttons on the tv will choose.
PS: GREAT writeup on your problem and the things you have tried.

The remotes have several device keys at the top of the remote. They have abbreviations like "VCR", "DVD", "TV", "CBL". By default some actions are locked into a specific key. By default, the volume buttons will always control the TV volume and the channel buttons will always change channels on a digital box.
If you have a digital box, and the channels wont change, the default locks might have been removed. Consult the instruction manual that came with the remote and re-lock the buttons to the correct device key. Otherwise you will need to press the "tv" button when trying to change volume and the "cbl" button when trying to change channels.
If you do NOT have a cable box and are just simply trying to use the universal remote as a primary remote, you will need to unlock the global channel lock. Consult the manual for the remote or check online for the remote guide. The Company which makes the remotes is called Universal Electronics and you can find digital copies of their manuals on the Brighthouse Websites.

Go to menu on front of tv, scroll down to source/input heading.Use the volume or channel select buttons to change the source

It took me a week to find the right instructions and codes on how to do this so I am posting it everywhere I can to help out folks with the same remote. Pay close attention to the instructions, for instance when programming the remote for TV use make sure you hold the TV button down while you enter the code and then press OK, You also have to hold the TV button down while you use the volume and channel controls or it will just change the VCR channel.

Changing Remote Control Code

This Remote is capable of transmitting two control codes; one set
to respond to A code control signals and another set to respond to
B code control signals. This Remote control is preset to send A
code signals because your VCR is initially set to respond to A code
signals. You can easily modify your VCR and the Remote to
respond to B code signals. When using two JVC VCRs, set two
VCRs and their Remotes to different codes, so that you can
operate these VCRs separately.

plug your cable connection to a vcr "in" then run a seperate cable cord from the vcr "out" to your television (which should be on channel 3 or 4) depending on your vcr setting and use the vcr to control the channel so when your westinghouse freezes and becomes unresponsive you could still change the channel and so on through your vcr and tv acts like a monitor works for me. N.B be sure to set the volume and so on before it freezes which could be like a 1min window from turning your tv on
