My 52" RCA P52937SG screen bows on the top and on


What you are describing can be due to a number of different settings.

Focus on the red and green guns
Sharpness on the red and green guns
Horizontal position and size
Vertical position and size.

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top


Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

I have a HCN4727w samsung. Red/green shadowing. Bowed image


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

Samsung hcn4727w. All colors out of wack.Curve at top and bottem.Plus double images.


Aging eletrolytic capacitors cannot hold the voltages necessary to keep the color guns in alignment. This is NOT a problem you can fix yourself. The are DANGEROUS high voltages inside your TV which can persist for WEEKS after the set is off.
You must call a qualified service technican for repair.
