Question about Samsung PCN5425R 54" Rear Projection Television
The color tubes are lighting up on the bottom of tubes but no light coming thur the lenses.
These rear projection TVs don't have a ballast.
The video boards are connected to the CRTs to provide high voltage and video info to the CRTs.
If not video is present but the CRTs are lighting up then is more likely a high voltage failure. The part that might be defective is the high voltage block that distributes power to all the CRTs..
