dark screen on 35 inch panasonic tv. repairable?

[[email protected]]

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?

Great older T.V. Worth fixing, as long as the dim picture is clear. You
may need to adjust the G 2 on the flyback, or more likely it could be a
bad couple of electrolytic capacitors. May even just need some
soldering, for bad connections, especially if
there is a video input/output board in the set. Dani.

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.

I'm betting on the common 1/8W resistor on the ABL line on this one
also.

I have fixed several Panasonic TV sets by replacing the ceramic capacitor
on the CRT board that goes to the G2 (Screen voltage) pin on the CRT. The
cap gets a little bit leaky and drags down the G2 on the picture tube.
Replace the cap and all is golden.
