I have a ten year old 35" panasonic tv that has lately started to have
a very dark picture. Even with the brightness turned up all the way,
when the characters are in a dark scene the screen is almost completely
black. Any ideas on what the problems are and if it's worth repairing?

Is the onscreen display dark too or is it normal? I fixed a big CRT set
a few years back that had a very dark picture but OSD was normal
brightness. I finally tracked it down to a tiny 1/8W resistor in the ABL
circuit thanks to a tip from this newsgroup pointing me to that general
area.
