I have a sony projection tv. Colors/piture not right


Replace convergence ICs and a 5 amp pico fuse on power supply. ICs are part number STK392-560.

Just be sure to use thermal paste on the ICs or they will self destruct in a short amount of time.

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Red and Green have separated in double image and there is a dip at the top. Please Help.


You have a defective CONVERGENCE IC. Most TV use 2 identical STK IC & both has to be replaced at the same time. If you are not a technician I don't recommend doing it yourself. There is a lot of desoldering to remove the chips with 16 or more pins- and soldering the new ones.
Good luck! Astrotech

Color adjust


Greetings!

Adjusting the picture tubes is a scary proposition, but since you have already done it...
The easiest way to balance the gray scale is to turn the color all the way down on the set. The next part is easier with two people if the screen controls are on the back of the set. This is the part you saw that has six small knobs on it. There are control for the focus of the red, gree and blue and for the screen level of the red, green and blue. You will want to adjust the screen controls in an effort to get the picture black and white (this is why you turn the color down), hence the term "gray scale". Just make slight adjustments, take your and be patient. It will take some time, but you will get your picture balanced back out in time.

Hope this helps!

Sony 65 Inch Projection TV Color Red Green Separation


Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.

JVC MODEL # AV-48WP74 48 IN. BIGSCREEN TV.


I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce
