Panasonic HD Projection TV PT-53WX54J Linearity Help

The vertical linearity on this TV is out of adjustment. images across the bottom of the screen are quite squashed vertically. Does anyone know how to access the service menu?

I found info on the WX53 series but it does not seem to apply to the WX54.
Thanks, John.

This is the vertical problem,it is a bad capacitor you must replaced all electrolytic capacitor in vertical section and resolder all associated parts there,so it works better again.

Hope it will helps you;

if the led is blinking one time its the 140 volt circuit. If its blinking a series of 3 blinks its the convergence circuit

It's your convergence IC, replace the two STK392-110 IC's.

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.

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
Rylee

Problem with Panasonic PT-53WX54J 53 in. Rear Projection HDTV Television - Green Screen


You may have a component failing in the red drive stage possibly the blue as well or even the quadrature stage. A can of cold shot should help narrow the search considerably. It is also possible the red and blue projection tubes are nearing the end of their service life as well. If you have the means to test the tubes themselves, check the red and blue tubes for gas.

Hi Their, I have a Panasonic TV (PT-53WX54J) That wont turn on can you help me please...


Please do us a favor and rate this solution after reading.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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 pics of convergence problems.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Common 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.

Top of screen disappeared...cant see score of game


The Height adjustment is off... look in the back of the TV set, it has some knobs in the back, one should be vert.lin for Vertical Linearity adjustment, and there is another call Vert.Hgt. for Vertical Height adjustment. try adjusting the Vertical Height first with someone watching in the front of the big TV to see if the top comes back into view, you might have to adjust the knob very slowly one way then the other way, to make this adjustment. If it doesnot adjust take it to a TV shop to get it repaired.
Good Luck.

TV not working properly


You have a vertical problem. See if there are any vertical (height or linearity) controls to adjust. Often there will be screws or knobs on the back.

Otherwise, it could be bad transistor or component in the vertical-deflection circuitry.

Hope this helps. :)

Tube tv problem with picture


There should be controls for height and linearity. They may be labeled as Vertical, Hold or Size.

Hope this helps. :)

TEAC CT-M685


This is a vertical-deflection problem. Try to adjust the vertical (height and linearity and hold) controls, which should be screwdriver potentiometer controls on the back of the set.

If this does not work, a defective component in the vertical-deflection circuit will need to be repaired.

I hope this helped you. :)

Cannot adjust convergence, screen has rainbow effect


You probably need to change out the semiconductors. The parts are STK392-110. There are two of them, one for horizontal and one for vertical. Search it online more.
