Fixed my Soundbar’s faulty remote

I have a Phillips sound bar, must be about 6-7 years old. Today while watching TV, I couldn’t increase the sound volume using the remote, and unfortunately using the remote control is the only way to change the Soundbar’s settings.

Update 16 Feb 2021: It stopped working again but this time it was a dry soldered IR LED. Reheated (or in simple speak, resoldered) the contacts and got it working again.

Then I took few drops of isopropyl alcohol on my finger and smeared it on the PCB as well as on the rear side (contact side) of the rubber sheet with buttons. Let it dry for sometime then tried to test if it works, and it did!

E-waste and money both saved, or I’d probably have to buy a new remote which might have been difficult to procure given the age of the Soundbar.
