Re: How to access Vizio m652i-b2 service menu

Thanks nomoresonys. I don't think this tv actually has a service menu. Or at least that's what Vizio support told me.

Also learned that while the board number of the replacement board I purchased is a possible match, the actual part numbers are different. Same board number can be revised and used in different models. So identifying the actual manufacturer part number is the best way to order. For my tv, this was hand-written on the back of the card. Including details below, in case it helps others in the future.

Been trying them all. No luck. Tried holding Exit for 3 seconds. No luck.
TV has been on when entering codes.

Re: How to access Vizio m652i-b2 service menu

Thanks @nomoresonys. This unit doesn't have channel buttons on the tv though, and I have tried using the remote's CH+ and CH- buttons several times without success.

Have also tried:
Menu, 1, 9, 9, 9, back
Menu, 1, 9, 9, 9, last channel
Menu, 4, 2, 1, 0
Exit, 1, 2, 3 Exit
Menu, 2, 4, 8, 9
Menu, 1, 2, 3

Other thoughts?

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!
