From the picture quality here they are fine (though much worse than for example. My 5 year old Sony Bravia LCD), sound is "adequate for the price", ie I would get myself a fit, but for the laws klingts better than before. .. :) operation also quite alright, something "faster" for example. when switching it could yet be that device.
But what is really the crux of the matter, is the software. When TV in the bedroom constantly sorting the more than 300 cable channels has returned to 0-9A-Z. A couple of times I have had my in-laws in suspicion, but after they have assured me, absolutely nothing special dodge (not adjusted in the menu), there are no problems in living room TV and all now the 4th time has happened, I'd bet on a bug in the firmware.
Yes, the brave new world so, where TV will be regularly updated with new software. Unfortunately, there no more current than the software that exists on the device, and so I have the bedroom unit now returned to Amazon, which worked out without difficulty even after more than 3 months of use by a telephone call to Amazon Customer Service.
Oh yes, before I naturally tried to clarify the issue directly with the manufacturer, but from there is ever any feedback came to my support request.
