RX450h on/off function on volume button not working

[nikkinakkinooow]

Asking for help/ideas....

This morning the push on/off button on the volume button decided not to work.  I assumed the whole radio/CD was not working, but I went through the menu and turned the radio on, the volume button would work (the up and down function for volume), it just seems the push on/off function not working.  

Haven't had a chance to have a proper play yet, but just wondered if anyone had experienced this and if they had solved the problem?

Any help gratefully appreciated.

If it's packed up just buy a second head unit from a breakers and save your self hours and hours trying to fix it .but hey it's your money .

The push button is a physical thing so is it still 'pushing' as in clicking when you push it?

If the physical action is still there then it may be something electrical, but if there's no click then the switch itself has failed, in which case I'd take it out and look for a replacement at either https://cpc.farnell.com/ or https://uk.rs-online.com

Many thanks Lager Shandy & Herbie.  Got back in the car yesterday and all was working fine!  So now doubting myself, I guess time will tell......... !!!
