i have changed batterries with new one , but no luck. as you write it is on top left , not right.The TV button, on my VU+ Duo 2, is on the top left, and indicates when you press a key, on the remote.
Have you tried changing the batteries?

I have now checked the sensor and Clean it , but no luck. Have turned off the receiver for 1 hr , no luck. I have not chenged setting or image recently. Regardless which button i press nothing happen , only the button ( TV) , which is located on the top left side of the RC is lighting , usually the LED light ( middle lamp ) of RC should light.At least you know that the remote control is working, as the TV button flashes, so the problem might be your receiver, check that the sensor, on your receiver, isn't blocked, and try cleaning it.
Also you could try turning off your receiver, at the rear, for a few minutes, and then see if it works.
Have you changed any settings, on the remote, or your receiver, or recently changed your image?
If you remove the black plasic cover at the top front of the RC you can se LED light ( middle lamp ) . I use the same original RC since 2014. currently i use my smart phone and my mac book to controll the box. I want to buy anothe vu+box , the best one ( i Think vu+ultomo 4k ) , but i am confused with tuner should i buy. I only have sat dish with normal LNB ( not unicable ) , i want to be able to Watch a channel and record Another one on samme transponder. I Think about 1xDVBS-S2XFBC Twin and 1xDVB-S2- Dual. Whats difference between Twin and dual ? i want both FBC and non-FBC tunner , because i read somewhere that non -FBC tunner is more sensitive than FBC-tunner, is that right ? Thanks in advance.No other light on my remote.
Are you using an original VU+ Duo 2 remote?
How are you currently controlling your Duo2?
You can connect using your PC, by typing in your receivers IP address, and using the virtual remote, on Openwebif, or connect a USB keyboard, or try a wireless mini keyboard, with USB wifi adapter.

Thank you for your reply , but i still do not understand difference between twin and dual tunner ?You can record, and view, all channels, using the same transponder, even on a basic satellite receiver.
If you have a twin, or quad, LNB, you can run extra cables, to your receiver, and record, and view, multiple transponders, on the same satellite, or record 2 transponders, at the same time.
You can also add other dishes, or a dish capable of picking up different satellites, and view/ record, from any of them, using a Diseqc switch, or just connecting the dishes to different tuners.
