Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Red ghosting I have a Panasonic PT-53WX54J and think I might need to replace the convergence chips. I have tried to adjust the red, but the red will not go all the way to where it will line up. Can you help me with this and where I might be able to buy the repair parts. I will also need step by step instructions. Thanks

Your symptom sounds like a damaged convergence IC.

This is a common failure for this particular television. The blinking lights indicate a short in the power supply

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. They are secured to a very large aluminum heat sinkred ghosting - 2.gif. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics2.gif in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts. I believe that these kits come with instructions for your brand of Television.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Panasonic cinema vision pt-53wx54j does not turn on. red power led blinks 3 times.


Hi


Thanks for using FixYa. 3 blinks means convergence output failure and to resolve this you’ll need to change the convergence chips which are located behind the black heat sink; you can see once you open the back off the TV. Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thanks

If you go into the customer menu and select convergence and it is skewed you need to remove the light box and replace both of the STK-392-110 CONVERGENCE IC chips this set uses.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--I can post them here if you think you or someone you know can do the repair.

Most shops get 300 or more for this repair--if you buy the chips on Ebay (I can tell you the seller to look for there) they and any other parts should total under 30 dollars. The fact that the set is still coming on means most likely just the two chips need to be replaced and the set adjusted with the Panasonic remote for this set.

If you have questions or want the instructions rate this solution and let me know and I will post them here---I do this here for FREE.

I have a Panasonic PT-53WX54J that will not Converge


you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Pt-47wx53g has red ghost. I tried adjusting convergence but some will not adjust


You have a problem with the convergence output IC's. They need to be replaced. This is a very common problem with all projection tv's as those IC's are high current components.

Ghosting in Red, Green and blue


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix
