Question about Panasonic PT-47WX42 47" Rear Projection Television

47wx42 - wavy red and green "bars" on top and bottom of screen

Turned on the tube and am now seeing red and green bar areas at the top and bottom, along with seeing these red and green areas offset (like a convergence problem). Is this the evil STK392-180 chips gone bad??!! Thanks

Replacing the two STK392-110 ICs didn't do it for me. But you can try. I am experiencing the same problem, and it appears that is not possible to correct the problem with the ajustments in Service Mode. Please let me know if you find a solution to this problem. TIA.

Program columns are out of place

See if you can click and drag the start menu bar back to the bottom of your screen and then try to do the same for your program panel to attach it back to your start menu bar.

Also make sure your task bar is not locked by right clicking on it and seeing if there is a check next to it.

RED AND GREEN DOUBLE AND BLUR PICTURE HELP PLEASE

You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"

Sounds like a convergence promblem.

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

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.

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.

What is the life of a big screen tv?

Sounds like the veritical circuit has a bad capacitor. The cost is dependent on the servicers in your area. It can also be dependent on whether you take it to the shop or have a servicer come to your home. Look on a Mitsubishi website to find a servicer in your area.
