Led samsung remote doesn't work

[crdz66]

Hi everyone.

I need your assistance.
I have a led samsung tv un46f6350afxza with remote control not working.

I test couple remote control on another samsung tv and working good.
History.

This tv was working good until the tv start turn on/off too many times.
I decide change the main board and the problem was fix it, means now work properly keeping on and wifi working good.
But, since i change the main board the same remote stop working.
I already check :
As soon you press power on you see on ir board the voltage drop from 3.3v to 2.8v.
The joystick back of the tv working good let me turn on and off.

What do you think guys?

You most likely have a bad IR sensor. Or check the pins that connect that to the main board. Make sure nothing is bent or pins in the ribbon popped out.

So no remotes work the tv or just the one you have for it? Is it the intelligent touch kind or just a standard IR remote?

It's not intelligent one.
I have three samsung remotes on none working on this tv

That voltage drop doesn't sound right. Test your 3.3 V at main board with IR disconnected and see if that drops as well

Well back on this tv still the remote doesn't work.
I wondering if the voltage on main board show .6v (on pin IR) is right or need to be higher.?
I replace the ir sensor and still doesn't work.
