I have this tv that turns on and the menu and volume down buttons only work. All the other buttons bring up the same menu with the remote. the buttons do the same except they bring up a different menu. Is there a reset for this or a firmware update?

Re: RCA 42LA45RQ need service manual
It sounds like your main board is fouled up. Have you verified all your voltages to the main board? I didnt find a manual for this model, you may be able to reset the eeprom, but you would need to post sharp up close pictures of your main board so the techs here can see where the prom might be.Liberating magic smoke one part at a time

The current main board on my Vizio m652i-b2 only has 1 of 4 HDMI ports working. Also, the coaxial port is not working.
So I ordered a replacement board. It boots up the tv, but the display is dark in areas, colors are off, etc. I have seen information online that a setting in the service menu may need to be adjusted. Have tried many ways to access the service menu using remote codes, but none work.
Can someone here provide the confirmed method for accessing the service menu on this tv? Thanks in advance! -
