Question about Panasonic PT-53WX42 53" Rear Projection Television

2 Answers

Pt47wx42 convergence The blue gun on the bottom half of the picture won't converge with the other guns. This is not a minor difference. It is way off and has actually formed an arc across the bottom. It happened when I pressed aspect ratio on the remote. Any ideas? Thanks for the reply.

Yes, I have and idea, and it has nothing to do with the aspect ratio. One of the convergence output IC's has failed. This is a very common failure with all projection sets. Average repair cost by a reputable repair shop is around $200 to $300 depending on where you live. BTW that set is well worth the repair cost.

Your TV may have a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem



  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
Solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Blue Projection Gun


It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.

Bent image


Excelent description,whats happening is your set starts to show a blue convergence problem and is only correctable by replacing the blue convergence amplifier IC,the set has 3,one for each color,not all of them develope problems but they all develope loose conections,after the IC has been replaced there are adjustments to do.If you are familiar with tv service this information will give a place to start but if you are not too familar be safe and call a servicer to help you.Lets US know how it goes.
