Long time lurker, first time poster here.
I'm the owner of a Sony KDL52W5100. It's got 4 HDMI ports and one by one, in the 18 months or so that I've owned the TV, they have all failed. The last one went over the weekend. The symptom is that the TV will not show picture or output sound from the source, however the input selection menu does show the blue icon indicating that something is plugged into the port. It seems like this always happens just after a power outtage, or during a storm. I have taken to unplugging everything whenever I'm not watching television, but I guess this time it had nothing to do with it. I also own a PS3 (my second, as the HDMI port in my first malfunctioned as well) and I own a Sony HT CT100, whose HDMI ports have also burnt out.
The TV is what I'm most interested in getting more information about. Does Sony have a history of very sensitive HDMI ports? Is there anything I can do to prevent this type of thing from happening again?
I've purchased a new bu board to replace the existing one. I've done some searching and I'm hoping to implement a more complete surge protection solution. Unfortunately, I rent, so making any major changes to the electrical system of the house are probably going to be impossible.
