Bought in 2008 (xmas) suddenly lost picture, including menus, etc. Sound still works. Found blown fuse on t-con board. Jumpered with 3A auto fuse, now works fine. I have 2 questions:
1. How common is it for a fuse to just "go bad"? Can I expect the problem to recur? Ran it for 6 hours and the new fuse didn't blow (I expected it to blow immediately when I turned on the set.) I used a 3A fuse because it was the closest plug type fuse to 2.3A. I can't read the tiny writing on the old fuse, but I tried to measure it and the only thing I can find which seems to match in size and appearance is a ROHM ICP-S2.3TN.
2. This part is really, really tiny. Is it really necessary to replace the original part or can I just button it up and use it with the jumpered auto fuse? Not too confident about removing tiny SMD device without doing more harm than good.
Rhetorical question: What is the point of this fuse? Panasonic considers the t-con part of the panel and not replaceable or serviceable. Then how does a blown fuse differ from a damaged board? What is this fuse protecting?
