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

1 Answer

Pt-53wx47f i just replaced the convergances chip with the ones you had posted, stk392-110. all went well and it seems to work fine with an input of 1080i. but with 480p it seems to still have the old convergance problem. just wondering what might be up. if switching out the resistors would solve that problem. thanks for helping get my tv looking great in high def, and any help getting the 480p back in order would be awsome. thanks - tom

    the convergenace in the 480 mode has to same problems as before i fixed it. the red and blue channels will not match up with the green. the green seems to be to far to the right. i have tinkered with it for about an hour. might there be another explination? it is better then before, but not quite there yet. while 1080 is back to normal.- thanks

You will need to do the convergenace adjustment for each different format then save each setting for each adjustment.

This kind of problem occurs due to failure of convergence output chips located on main circuit board of tv and replacement of convergence output chips will hopefully solve your tv problem.
Soldering work is involve to replace these two chips so have local tv repairman for that job if you are not familiar doing so.
Thanks.

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top


Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

My panasonic pt-56tw53 picture was not looking righ all on adjusted - went to the converge set up and now lost whole picture just shows all colors in middle on tv zig zaging


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.

Your TV most likely has a 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com . They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Ic chips


Hi did you check resistor protectors they are green pico fuses.

check your connections make sure all the wires are lined up with correct ones. I have done that lots of times.

In the menu you have to go to convergence and readjust the cross hatch each tv is a little differant to get to service menu you for adjustment..

keep me posted get me model number and i will get convergence code or the way to get into it for you .dont give up you will get it sometimes i go back to peoples houses a few times.
thanks doctor video.
