You may not need to remove the red wires, normally there is enough slack to be able to turn the board over just enough to be able to remove the chips. See where the wires are running and losen any clips/ties holding them in place. If you still think you need to remove the red wires normally pushing down into the black thing and twisting 1/4 turn then pulling it out slowly will work on most of them.Some red wires have a metal clip on the end with tabs on them which requires twisting it to get the tabs lined up properly. others have no tabs at all and just require pulling out. I would error on the safe side and try the first method. good luck

Hi,
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-47WXC43G green ONLY is bowed on bottom and top


Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

I have a Panasonic PT-56WX51E that started showing double images with a green & red tint, above the original image. I have attempted to connect straight to the box, using DVD & VCR to see if the...


This is really a very simple thing to diagnose---go into the customer menu and select convergence--if red or blue is skewed there and will not adjust in some direction--you have a convergence circuit problem.

These sets use two convergence IC chips--if convergence will not adjust you need to replace both chips along with any of the resistors around them that protect the set and are bad.

Parts are cheap for this ----less than 30 dollars for everything you will need.

Based on the Pt56wx51e model number this set uses two of the STK-392-110 chips--they are black and side by side on metal heat sinks with fins and will have the full STK number printed on them in white letters.

Most shops get 300 or more for this kind of repair. If you or someone you know can do it you can save a lot of money.

The repair really only involves two things: getting at the chips and parts and being able to unsolder and replace them.

I HAVE START TO FINISH STEP BY STEP INSTRUCTIONS FOR THIS REPAIR ON THIS MODEL. They will tell you everything you need to do the repair and how to do it--I have fixed hundreds of these sets with convergence problems.

If you think you can do it let me know and I will post the full instructions here for you.

Once the problem is fixed the set will not have the same trouble for 5-8 years--lifespan of the parts.

If this has helped you rate this solution as I do this here for free.
