    ok. I double checked the model number. on the back of the tv there is a white sticker. on it says Model NO. PT-61D30B
    Chasis No. ? EP816

I believe it is the video board itself you want to replace on this unit. I am having a hard time locating this part though, I will keep checking for you though.

Hi

Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs tobe replaced. It's not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you'll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. Please check this picture:

There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do accept the solution if the issue is resolved or post a comment for further assistance.

Thanks

Hi,
Please reconfirm model number of your tv as PT-61D30B sounds incorrect number.
Regarding convergence section/ board, usually there are two big black ICs mounted with big aluminum heat sink on deflection circuit board and ICs number would start with letter STK,,,, these are convergence output ICs that need to be replaced to fix the problem.
Now let me know correct model number of tv to provide you more helpful info.
Thanks.

    STK392-110 is part number of convergence output ICs in this tv
    Also mentioned where you can buy this IC, tv needs two ICs of this same number
    Thanks

    Shahid Electronics Oct 02, 2010

    Yes, replacement of these ICs will fix convergence problem,
    you should not attempt to replace these ICs if you have no prior experiences of electronics stuff repair as soldering work with proper tools is needed.
    Local tv repair shop will help you.
    Thanks

    Make sure convergence chips are getting power that is +20V and -20V

  • Shahid Electronics
    Shahid Electronics Oct 08, 2010

    Convergence chips are those ICs that you replaced in tv, STKxxxx
    They need power supply to work properly so check are they getting volts as mentioned before so they can function to converge the picture on tv front screen.

I have a Panasonic PT-53WX54J that will not Converge


you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Panasonic PT-60LC14 Convergence Issue


Projection TV sets have two very common problems listed below.

Problem #1) 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
*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

COLOR SHADOW


This tv does not have a lamp. If you can not adjust the convergence, then that is the problem. Yes the amps will have to be replaced. I would get this fixed and not scrap it. You can try and replace the amps if you find the need to or have a repair shop do so.
