Question about Panasonic PT-50LC14 50" Rear Projection HDTV-Ready Television
I went ahead opened the back
cover and surprisingly noticed it's pretty dirty inside after 2.5 years
of usage, and there is a thermal fuse to protect the ballast power
supply. Spend 99 cents replaced the thermal fuse and the TV came back
alive. I am surprised that it's such simple to fix the problem vs many
LCD TV is more fragile than the traditional TV as it uses expensive HID lamp. So the cooling system inside is very critical to prolong the lifetime of the lamp and the special power supply. Dirt collect inside is probably the major cause to degrade the cooling system. Make sure you clean them (two fans and a lens) whenever you have a chance.
