Panasonic Projection TV PT-47WX49E convergence ...

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• 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.
• TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.





SOLUTION #1

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common 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.

converge outputs getting tired or limiting resistors opening up. adjusting this incorrectly will make the situation worse keep in mind that overdriving these chips will cause a fold over of your image when you see this carefully adjust in the opisite direction as you may be overheating the outputs

i need the service manual as well, if possible (i'm just having a red horizontal convergence issue).

also, any advice on what to do would be swell!

thanks!!

If Convergence on setup dosen't work, And you think its not STK Convergence chips!, Then "Yes" It more then likely will have a few open Resistors!... (Near STK chips)

got this used cant get remote to work

If it's really bad and happened all at once, your convergence amps have failed would need to be replaced before you could correct the issue with an adjustment.
