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.

Pt47wx42 convergence


Yes, I have and idea, and it has nothing to do with the aspect ratio. One of the convergence output IC's has failed. This is a very common failure with all projection sets. Average repair cost by a reputable repair shop is around $200 to $300 depending on where you live. BTW that set is well worth the repair cost.

WS55511Mitsubishi TV convergance problem


Your TV most likely has a problem in the convergence circuits. ( 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, 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.

Color bending


Go into the menu and look for Screen Convergence. It may also have an auto convergance option try that first. If it gives a suto error or you cant adjust it manually the convergance IC's may be bad or a component on the convergance board.
