Hope its ok to start thread on this topic here.
We went away on holiday for 2 weeks and not return there is no response when remote button is pressed.
Attached are photos of the internal guts and the main board and power board.
There does seem to be any obvious failed components
I'm wondering where to begin troubleshooting.

begin with a new battery in the remote - just in case!

Yes, already eliminated battery problem as there is no response to wall remote either. Even called Garage Door Service. They wanted to install new system and said the unit has been superseded. It was only installed 8 years ago.
Anyway went to local hardware depot got and installed a new DIY unit.
Just want to tinker with this before giving away as its a sturdy unit with metal chain.
Could only attach 1 photo earlier so photo of boards attached here.

What a surprise! There was one capacitor that had slight bulge on top, so decided to replace it. Only had 1000 mF leftover from previous Samsung repair so put that in and guess what? It worked.
The opener responds to remotes perfectly! The blue Lelon is the defective cap in the attached photo.

Bad caps in your garage door opener... who would have thunk of that?!

Good job with the repair! Those folks in the garage door "repair service" have nothing on you, lol .

I noticed the picture was upside down, but then I noticed your country:

so now you can take back the new one and get your money back.

One could reasonably expect that service technicians would know the common faults and at least do a bit of troubleshooting.
All the guy did was check power and operate the remote. When there was no response or click it was obviously a receiver/transmitter problem.
It just seemed ridiculous to scrap a perfectly operating unit just for that.
