Re: WD-73735 Dim after bulb change

Ballasts are a common failure as these sets age. You've swapped the lamp already, so swap the ballast nest. If problem still persists, suspect a bad lamp. There are lots of bad ones out there and you never know who may be pawning off crap for brand name merchandise.
