Panasonic PT-47wx49 color distortion

The colors have seemed to have separated (ie. blue, red, green. images are "ghosty". I bought it in 2002 and am wondering if the bulbs just need to be replaced, and if so, how easy(pricey) is this to do.

    same problem, but mine is a PT-47WX53G 42 in.

    Is it difficult to fix? E.g. part not available, difficult to reach inside TV, extensive test?

1) Replace both convergence IC's...located on large heatsinks
STK392-110 use Pana,Toshiba,Philips or upgrade to my
choice.....Hitachi ( Mfr'd by SANYO ) Part # CZ 01341....

2) Check 2.2 ohm 2W B+ feed resistors for over-heating....

Note: Requires chassis pull..technical & soldering ability a must.

After lamp replacement, why is picture still green?

it seems like the green was not defective before you replaced the green. remove the red =no change in the screen color, that could be bad. put back red, then remove blue=screen color changed, blue is good, hope you got the idea.

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Panasonic pt43lc14 no red color. picture is good. cannot get anything to look normal color after trying to adjust color/tint/picture etc. Have alot of blues and yellow, and brown. seems like no red.

It appears that your light engine is broken, I have the same problem. Have you recently changed the bulb with a non-panasonic part bought on the internet. I did this and think thats what caused the problem. I believe the new bulb burn at a higher temp thus causing damage to the Light engine filters

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)


Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.
