I'm a logical thinking kinda guy but this has me scratching my head. Batteries in my Sony 930 receiver remote were running low so I whipped out the Sony ones that came with the remote and chucked in some new Duracell Plus. Press the source change button, display lights up but no information appears on the screen. The screen stays lit (usually dims after few secs) I can still change the source if i press lots of buttons but the backlight does not go out. I eventually have to remove the batteries to get the light to go out. Try again works for a while then does the same. This carries on until I put back some Sony batteries out of my TV remote in, all is well. Month or so later and NO lockups, the Sony batteries go dead, I decide to give the Duracells another try, works for a few days, then again it freezes!? Does anyone have any ideas why this is doing this?? Thanks Dom.
