Hi everyone, I am having an issue. I have the Sony Sound bar STR-CT550WT. Just today I was able to control it with my remote from my TV. I had it all set it with the IR blaster and everything. But I just changed the batteries in the remote and now I can't control my soundbar receiver anymore! I don't know what happened. I can't change the volume or power the receiver on or off. If I turn off the IR Blaster option then I am able to change the volume but still not about to power it on/off. I tried all the codes but nothing works. Maybe someone can let me know what I may have done wrong or forgetting. But I just don't see how changing the batteries could do this. Thanks for your help!
