Replace IC Convergance chip in Panasonic PT-56HX41PF

I'm trying to replace the convergence chips in my Panasonic PT-56HX41PF, I need to take the board itself out to sauder the chips into place. There is a four white connector that is holding the two boards together, I do not want to force them out, they may break. Has anyone done this, if so can you please help?

    Dave I have same problem with these connectors. Did you manage to get them undone? I also have a problem taking the anode wire out of the FTB.

Enter the tip of a pointed knife between the left side edges of the connector (circled in black in the attached pic) and gently tilt the knife away from the connector. Do the same on the right side. The connector should pop up.

3 times red light flashing is an error code that indicates problem in convergence output section, please check and replace convergence output chips and pico fuse nearby. Chips replacement in circuit board requires soldering work and local tv repair shop will help you if you are not familiar with soldering.
Hope this will help.

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
