Re: Magnavox 46ME313V/F7 powers on and off
Thank you for taking the time to help me with this! I do not have any replacement parts but it seems we have it pretty well narrowed down to the ir board so I'm just going to replace entire board.... $10 on SJ so not bad at all.

Re: Magnavox 46ME313V/F7 powers on and off
And to partially answer your question HidesertRat; the function board feeds into the ir board and then into main board. I can disconnect the function board and it has no effect. Have to disconnect the ir board before anything changes. My initial thought was a bad ir board but I'm not sure what to test to make sure before I order replacementLeave a comment:

The only way I could keep it from continually powering off and on was to disconnect the connector for the ir sensor board. If... -
