Hi, I'm new to the forum and tried searching for a previous post about my problem, but didn't find anything. I have a TX-47F430S that I bought in 2008. It lives in the basement, and as a result, has not been used much at all.
Over the last few weeks, it has started losing the video drive signal (as near as I can guess). I primarily watch my Dish Network TV box through the HDMI port. It will work fine for a few hours, then the picture will suddenly disappear, but the audio continues to work and the LED stays blue. There is no "No signal found" message, and I can't get menus or anything, even internally generated, to display on the screen. Likewise, switching to the TV antenna input also produces only audio with no video. I can see the back light lamps illuminating, so I don't think it's lamp/drive problem. It really seems to me like the video just somehow gets "disconnected". If I do a hard reboot (holding in power switch for 10 sec), it comes back and works fine for a while before the whole cycle repeats.
Anybody seen this before? I thought I'd try a firmware update, but it seems Westinghouse no longer makes it available on their website. Any working link would be appreciated.
