Question about Sony KP-61XBR48 61" Rear Projection Television

1 Answer

When tring to use the red convergence it seems to be twisting.

The bottom half of red convergence somewhat aligns with blue and green, while the top half stops/sticks before aligning. seems to be twisting rather then the usual up and down alignment motion.. is this my red board or cr board? is this an expencive fix? can it be done by me?

    I don't know what the problem is but I can tell you the site Jean posted will not fix this issue. That sight refers to a specific issue that is common on Sony sets. This sounds like a convergence issue to me.

    Look for 3 black STK's on a large heat sink. Change all three around 10.00 each at MAT electronics... Google it..

Hi I have a rca hd52w59. the top half of the


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

The vertical green convergence adjustment is broken


Either your convergence ic's are bad or the convergence digital module ( if your model has one ) . I would have it looked at by a service company.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Convergence ICs


the green is half controlled by half of each of the convergence Ics meaning green horizontal is controled along with the red and green vertcal is controlled along with the blue Ics. So if you have replaced both Convergencs ICs the problem is most likely a resistor that is in the green circuit. You will need a schematic to locate which resistors are in the green vertical and horizontal convergence circuit

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.

Green out of convergence


The green convergence IC is defective. this is not a job for the consumer to do as it requires the experience of soldering and unsoldering and the know how and the safty nissues concerning the HI voltage inside these sets. Please consult a pro to assit you in this matter. Good Luck
