It looks like I fried my TY-FB8HM board. I have a home theater with a TH-42PHD8UK that I bought in 2006. The set-up has served me well, but last night I tried to upgrade the receiver. I haven't tinkered with the system at all in about 5 years and it did not occur to me to unplug the TV before swapping the cables from the old receiver to the new. That may have been a mistake.
When the new receiver was all hooked up, I could not get a picture. I went into the TV settings and found that input settings for slot 1 were greyed out. No HDMI. So, I took the TV off its stand (damn these things are heavy) removed the screws, pulled out the board and inserted it again. Still no HDMI.
The TV works fine with the old receiver and component cables, but this is not a long term solution. I see VisualApex has the boards in stock for $289. I can also try to order directly from Panasonic. However, before I do that, I have a few questions.
1. Have I diagnosed to problem correctly? Did I fry the board?
2. Is it possible to have the board repaired? There is no visible damage.
3. I could just buy a new TV and move the old (component-only) Panny to basement. I would probably go larger, but I see budget 42 inch plasmas can be had for $500. Does it really make sense to spend $200-$300 on a new board? I haven't shopped for TVs since 2006, so have no idea how today's TVs compare to mine. I must say that I love my TV. Will average 2011 model TVs have a better PQ than my 720p Panny?
4. If I do buy a new board, where can I get the best price?
I am really kicking myself this morning. So much equipment today is plug-n-play that I did not even think to unplug the TV before swapping cables. I would greatly appreciate any help you guys can provide.
