Thanks. Do you have a cell phone camera or digital camera handy so we can test the remote please??

Expert:  Aric replied 30 days ago.

We need to test the IR emitter on the remote to see if the issue is your remote or your Mainboard. We need a digital camera or cell phone camera to see the IR emitter (it's not visible with the naked eye), Let me know so we can proceed.

I have checked the remote signal with my phone camera and it does blink
Expert:  Aric replied 30 days ago.

Okay, since the remote is operational and you already changed the IR sensor, then there's two possible culprits: 1) The IR sensor you received was weak/intermittent and failed after that initial use. Or 2) The Mainboard's processor that the IR sensor on the TV connects to is faulty. So, not sure where you purchased the IR sensor from, and if you've checked the remote SINCE you replaced the IR sensor, but if the remote and sensor are not the issue then the Mainboard in the set needs to be replaced. Let me know if you have any other info to help narrow this down. Those three things make up all of the remote's IR sensing and command processing in the set.

Oh, and one other thing to check is- ARE the TV's physical buttons working as they should?

I'm unsure why you're unable to reply, but I'm here to assist you if you need further help. Or if you're certain the IR sensor and remote are not the problem then the only other component in the signal chain is the Mainboard so you would need to replace that. Let me know if you need further assistance.
