Result of dismantling:
The remote control could be in spite of the 2 inside the battery compartment screws Dismantle poorly. To this end, the two silver strips had to be removed right and left. However, most tick broke off and the strips were no longer usable after. In the remote control, then was on the circuits for program selection and for loud and quiet an oily liquid. Removing this fluid but made nothing. After assembly, no improvement was observed. After all, the remote worked just as, with the quirks already described, as before dismantling. I think that these fine ribs just do not have contact with the corresponding buttons. It was not apparent to me whether it was because of these rubberized keys or on the printed circuit. The solution for such a repair should be performed only by an expert. At this point, everyone has to decide for himself a new part to buy, or to provide repair. I tend as a new part. If the customer images I have a few pictures of the disassembled remote control and an enlargement of the body concerned of the circuits and the rubberized buttons set.
After 1.5 years in operation!
Unfortunately, the keys go again to her mind to abandon. A button is no longer and the other does not as smooth as in the beginning. So it's just a matter of time before the next remote control is due. All in all, a grotto bad score for Sony. What is it for a botch? This is not a brand quality, which is just an audacity which is a da offered for the money. thumbs down!
