Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

1 Answer

Convergence Replaced stk-392-110 (2) and a blown resistor. TV finally comes on again! When I adjust the convergence for green center line, things are ok. I adjust the center + for red/blue just fine. When I have to adjust red/blue convergence on outer screen area, I am unable to get the 3, 6, 9 side of screen lined up. The red and blue "+" are bowed, and the channel logos on the lower right side of the screen are "ghosted". The rest of the picture looks just fine.

    I will check my soldering work again. I removed the resistor that had blown and replaced it. Thanks for your help.

    I only had 1 extra resistor, so I took a chance and added a bit of solder to the few pins that seemed like they had less than the others without checking the resistors.

    I lucked out! The extra solder did the trick, I don't know why it worked; but I do know that I am very grateful for all of the help I have received by viewing the posts on this site.

    Slinteriors, thanks for your quick response and accurate fix!

    I Replaced stk-392-110 (2) , TV
    finally comes on again! When I adjust the convergence for green center
    line, things are ok. When I try to adjust the center + for red it will not move right or left only up and down (It needs to move right) while blue adjusts just fine. When
    I have to adjust red/blue convergence on outer screen area, I am able
    to get the 1, 4, 7 side of screen lined up but again cannot move red right as it needs to (only up and down). Any Thoughts?

Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.

    Often 2 or more resistors go open with no visable sign. You need to remove 1 leg of all the convergence resistors from circuit and check them all chances are 1 is still bad.

Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks

check the resistors near the
stk's. There are some reports that they get fried when the stk's fry....or the other way around. The resistor ratings are labeled on the resistors. 2.2, 82, 180 or something like that. Also check the board as you turn on the tv. See if any glow red.

Ok, so I Replaced stk-392-110 (2) and......


Check the resistors in the red convergence circuit right next to the Ics you will need to lift one side of the resistor out of circuit to acurately check them but usually one or two resistors will be opened when the ICs go out

Green lines through out the screen


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.
