Panasonic pt51hx40b the picture at the bottom about 8 inches up and it goes to the middle of the screen.it is like the convergence is off.it is like 3d you see lite green and pink.the top right hand corner bit not quite as bad only about 4 inches.any help would be appreciated. Thanks Spaceace

do the proper isolation proceedure and try unhooking the Su from the SC board to see if you then get a normal picture all the way across the bottom half of the screen? I am assuming the Vertcal extends extends all the way from top to the bottom of the screen?

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

never adjust the tubes themselves( No-NO) these are affixed to the chasis in one position and not to be moved. no adjustments should ever be attempted to anything directly attached to the tubes. this will throw off centering, soft-focus, & convergence alignments. it can be corrected but a huge burr on the bottom of the foot! what you have are faulty convergence ic's and maybe sme low-ohm resistors that are bad. repair in-home should not exceed 350.00. parts and labor. mch

its the problem of convergence in the unit that needs to be repaired

You will need to replace both STK392-110 convergence Ics. You can get replacement ICs with free instalation instructions with pictures at the following link.

Sounds like your convergence chips are going. Unless you are real handy with soldering iron I would suggest having a tv repair shop service it(probably cost $200-300). If you are handy then I believe the chips you need are Sanyo STK392-110. There should be 2 of them. be careful if you order them online, there are lots of chinese knock-offs out there.

The convergence ICs are located on the left board on a huge heatsink they should be STK392-110 or STK392-120. You can get replacement ICs at the following link and they also provide free step by step instructions on how to remove and install the new ICs.

You need sevice code to enter convergence.

the convergence ic's are at fault need replacing,call a service shop and ask for estimate to repair .should be under $ 300.

the convergence ic's are breaking down and require replacement should cost under $ 250 depending on your service shop.
