Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Picture with red 3-D effect

All of a sudden my 4 year old Sony 52" rear projection tv produced a 3-D like effect with the red color. I adjusted the red inside but all it did was make it blurry and the other direction made it clear, but still off to the right. I ended up covering up the red bulb with a rag, and now the picture is perfect but everything is greenish/bluish. I have no idea what I am looking at inside the tv, but would rather fix it than buy a new tv.

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
*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

Odd picture....


Yes, your convergence is off. There is a function in the menu for adjusting these propoerties. It is supposed to be done monthly but rarley is. If it is ten years old or more, the cooling fluid in the projection tubes can get low, causing fish bowl effect. Not a cheap job and time intense. Try adjusting the convergence first. It gives you three screens to aling each color then save. Good luck!

Picture warped and colors not lining up


Good Day petepath7;

With separation of colors it sounds like the convergence IC's have failed., but first try unplugging TV from a/c power for 4-5 minutes then plug back in, if no fix see previous.l

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

Hitachi 52 projection tv


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
