Pt 53wx53 convergence

I recently replaced both convercence chips myself and successfully fixed the drastic issues i was having with on screen distortion in my pt-53wx53 projection tv. while the picture is almost back to what it was before the problem, i still have issues on the right and left part of the screen with the red convergence not being perfectly alligned. is this something i could fix by accessing the service menu and if so how do i get into the service menu??? i have done the regular on screen convergence adjustment several times but it does not have much affect. it is a minor problem that i could live with if i had to but i thought there might be an easy solution...

    Same here except my red wont go right. Did I mis solder a ic pin? Will service menu help?

    I had similar convergence problems on my Panasonic PT-53WX53 as many have posted here. Without previous experience, I attempted to replace the broken IC chips on the main board. Unfortunately I pulled off several tiny pieces of the circuit coating when I tried to remove the IC pins from the board. I would assume that I have damaged the main PC board and need to replace it (very expensive at $280). However, I am not sure how to disconnect the high power cable from the board, and how to disconnect this main board from the board connected through three connectors. Can someone help me? I would greatly appreciate!

    not of the solutions here see to be complete. I cannot get the red to converge to the right. Also the verticle bar on the red is curved. Please advise.

    Hello, I have a simillar problem for my unit, the green is way off, can't converge with blue and red, and the green curves on the top and bottom of the screen. I read on some post that they replaced the IC's, Any idea which one are those? Any help will be greatly appreciated.



    thanks a lot

    Sorry if I keep posting in the wrong place, I'm still learning to use this site. I have a Panasonic PT-47WXC43G with convergence problems. I replaced both the STK 392-110 IC's and checked the adjacent resistors. The resistors were all within tolerance but when I turn on the TV it powered up momentarily then shutdown on its own. The power light is blinking. What should I check next?

I am sorry, I don't have a solution. I have the same issue. I replaced the two chips, but I still get double images with green shadow. It is not that bad and I can live with it, but is there anything I can do to fix that also? Does it have anything to do with my soldering? Or is there any bad resistors? TV works fine with a little bit of adouble image with green shadow.

Any suggestions? Thanks,

Pt-53wx53 Panasonic Projection TV Turns off


OK< likely one of the new chips are bad or when soldered in you shorted pins at that time----3 blinks is short protection and you are going to find ONE of the light blue 2.2 ohm resistors is open (usually discolored in middle).

Having changed hundreds of chips in this model once in a while you get a new one that is bad---replace both again.

How did you get at them----remove the board or pull the light box?

Panasonic projection tv pt-53wx52c no picture red light flashing 3 times have sound


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.
Thanks.

Everything looks like its in 3D vision. Im pretty sure somthing isnt alined right so i was wondering what i can do to fix it.


Replace convergence output ICs in your tv to fix this 3D look picture, it happens due to convergence output chips failure.
Local tv repairman will fix it for you if you have no prior experience of part replacement in tv circuit board with proper tools.

I have a Panasonic HDTV Model PT-53WX53G. I am getting a 3D / Double screen effect.


This is the convergence chips. They are 18 pin Amplifier IC Chips that control your three tubes to line the colors up. They are only about $20 each (there is two of them). They are difficult to replace if you dont know how to solder/unsolder. There is usually at least one resistor or fuse that will blow when the chips go out, you must replace this also. If you have no experience in electronics then i'd suggest you take the set to a pro.

PT-53wx53g Convergence issue?


Both convergence amplifiers should have been replaced at the same time. If you can get your hands on a service maual, replace both of them, and go through the convergence alignment in the manual.

PT-53wx53g Convergence issue?


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Screen shadowing with colored lines


This is most likely a convergence problemand can easily be fixed. If you can solder you can repair this yourself. First try resoldering the pins on the convergence ICs. If that failes to resolve the problem, replace the ICs. THese are large black Ics attached to a heatsink and may be marked STKxxx.

Keep us posted.
