Question about Panasonic PT-47WX52 47" Rear Projection Television

2 Answers

Convergence??? Hi I have a PT47. It used to work fine, but one day out of nowhere the image lost its quality. It looked like a convergence problem at first, since the colors where misaligned, but after plating with it I noticed that the colors where also diverging away towards the sides (arches like) I am enable to align the colors together. Any suggestions?

If the sides are bowing in like this )( that is called a pin chusion problem, normally you have a problem in your vertical circuit, a tv tech would be able to narrow it down but a good thing to do if is scope your vertical pulse from the vertical IC to narrow the problem down

Suddenly we are getting a double image, red set and green set. Audio is fine. Magic focus doesn't help at all. Can you please advise?


Hi Steven,
If the symptom didn't cure by convergence adjustment through the remote control, this is an indication of faulty convergence board inside. You may replace the convergence IC's and some of the resistor around because its already gone bad. You may also replace the entire convergence board for your convenient. If the board replaced with new one, your unit will back to normal again. Also, consider bad solder joints in that area, it will do the same symptom like what you've encountered right now. Find it first and re-solder. If you don't have necessary tools and test instrument and can't do the job yourself, I would advise you to look for a qualified technician to isolate the problem.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

I have a Sony projection TV KP-53HS10. From one


It is most likely the convergence board. Rear projection TVs use three lights to display the image. The image is aligned via the convergence circuit. After many many hours of use the capacitors and resistors on the board lose their tolerances. It is very expensive to repair if you take into account the price for a new TV and the quality of the image you will be getting if you do have it repaired.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

I need to order a convergence chip for a sony does anyone know the cheapest way?????? thanks


Cheapest chip would not work properly or would fail next day and ultimately have to buy original or good quality convergence chip that would cost bit higher then cheapest.
Sony KP-51WH40 requires STK392-560 chip.
Part Store has $38 and $42
Electronix offers it in $15
Pacificsemi offers it for $20
Click above link to see image and price info.
Search on ebay for lower price.
Thanks.
