Panasonic blue convergence problem

I have a 2002 Panasonic (PT-56HX41PF) rear-projection, 4:3, HDTV whose blue convergence went out all of a sudden yesterday. I turned it on and the picture was awful. The red and green were fine, but the blue will not converge in the corners or on the sides (converges fine down the middle). Any idea what's going on?

Yea, you have to have the two convergence Amp IC's replaced. Should run you about 300 bucks or so. Good Luck

Panasonic (PT-56HX41PF) rear-projection tv with no picture

The three blinks indicates a convergence IC fault. The convergence ICs must be replaced with the manufacturer replacement part. Use only the original replacement part. Your set uses STK392-110 convergence ICs.
These ICs are mounted on a large heat sink. Yes, you can replace it yourself and save few hundred bucks. But you must be knowledgeable enough on how to solder, resolder and use a multimeter.
You will need:
  1. Convergence ICs
  2. Heat sink grease or thermal compound
  3. Soldering iron
  4. Solder lead.
  5. Digital multimeter
  6. Solder pump
  7. Small side cutter
Feel free to inform me if you decide to replace the ICs yourself
