Unresponsive remotes

[Alankellyeire]

Hey,

i have a solo2 and have been using a duo remote(without red LED) with it since i got the solo2 about 3 or 4 years ago.

Last week the remote stopped working so i put new batteries in it and it still didn't work, so i began to use the remote that came with the Solo2 until i could order an older model remote without the LED. Within an hour the Solo2 remote stopped working. the red light was coming on but it didn't seem to be able to communicate with the box.

i assumed since the issue was on both remotes it was an issue with the image or the box. so i cleaned the front of the box incase dust or something was interfacing with the IR receiver but no luck.
I used the TV remote for the last few days to control the receiver using HDMI CEC but it is missing a few essential buttons. While using the TV remote i figured out that if one of the remotes is unresponsive if i control the receiver using the TV remote the vu remote starts working again.

I assumed this is an issue with the image 5.0 build 23 i had on it so i updated to 5.1 build 6 and its still the same.

I'm at a loss what could be the issue as it seems to work intermittently and all the batteries Im using are new unused Duracell batteries.

I haven't added or installed any plugins/hardware/USB in months to the solo2 and find it strange this is happening all of a sudden.

Does anyone have any idea the cause of the issue?
