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

1 Answer

Can't correct green convergence

My TV was working fine until all of the sudden the convergence got horrible! I was able to correct most of it manually using the remote control, aligning the little crosses, but I can't fix the green. There are two lines (one horizontal and one vertical) that run across the screen when correcting the convergence of the green. My vertical line is in the middle of the screen like it should be, but my horizontal line WON'T BECOME CENTERED. It stays to the left no matter how long I press the right arrow on the remote. Any ideas? Is this a costly repair?

    I have the same problem, the green convergence has gone haywire. Everything else is alright.

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.

Convergence is off - Blue and Red are fine Green will not line up


On most units, the Green is constant and the Red and Blue are adjustable. Here are 2 links on how to manually adjust the convergence. There is a menu option using the remote control. Once there, you will find step by step procedure on how to adjust the convergence. Hope this helps answer your question. All the best!

Purple/Green Outline surrounding picture


I have seen two different things cause this. The first and most common is the electrical failure of one or both convergence IC's. A handful of times, the data in the DCU became corrupted and I was able to enter the service mode, go to manual convergence and correct the one location that was off.

Blue Convergence out of sync


you need to adjust the convergence. you set up convergence 1 then 2. follow the manual. (Its easy, you just align the + signs so they make one white one (instead of three green, red, blue) sounds like something or someone bumped the tv, causing the blue lens to shift a little.

My phillips model 60pp920217f has a horrible picture...no green to the color


The green CRT coolant has congealed thats whats giving you the green halos. Change the coolant in the green and blue and your set will be fine. red is never affected so the red coolant should be fine.

Hitachi 51SWX20B Convergence problem


Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
