Bauhn ir remote control receiver

[maxvalutech]

On this set a 58" model the ir receiver is mounted on underside of rhs of the set. The forward facing area is very small. I didn't have a remote control for this but have a Aultius set with similar fitting and as both are sold via Aldi decided to try the one for it and it worked. The Bauhn had the back panel off for testing other things, all went well so I reassembled the set. The red standby lit but I found trouble with the remote. It worked once in several tries to turn set on then nothing. Know nothing much about these, standby lights OK, how do I tell if ir is OK or not ?

Can you activity at the 'IR' pin of the connector with scope when hand remote is sending the signal?

Sorry budm do not have a scope. Any other way to check ? Every query seems to bring up remote sender info rather than receiver detail and testing.

It will be hard to see the digital signal on the IR pin without a scope, Check the voltage on the IR pin and see if it changes when a remote button is pressed.
Or try this simple circuit

Thanks people. As luck would have it when going thru some boards I have I found another ir receiver, not of same board shape but with same connector - hooked that in and it worked so tried swapping ir bulbs over but no luck so possible component problem on ir board or I did other bulb in !!
