Equipment good, but ....

I got me some time ago due to conversion from analog to digital, the same
3 piece SL 35 receiver, purchased because of the unbeatable price performance range. With the performance of the devices I'm still satisfied with what I can not say from the associated remote controls. With the most widely used in the living room it started: Pressing any button will not set off no longer the intended action of this, but the previously entered command an entirely different key. Time as an example: I have only changed the station and later I wanted to change the volume, the unit moved but again the transmitter. And that is in all 3 so what is quite annoying. As I read here, that is with me rather than the exception. To all abundance is me yesterday from ungodly reason a remote totally failed - whether batteries, fell down nor is it, now I'm forced me time to what to look new again by.
