Re: samsung 46in.

This is a Plasma TV set, there is no convergence adjustments on this set. the convergence adjustments are for tube type projection TV sets. You could have a few problems with your TV. You could have a bad color whell assembly, a bad light engine assy. or a problem with the main board. This is not a set a that some who is not trained on plasma TV sets should attempt to troubleshoot and or repair. depending on how old this set is, it may still be under warranty. if it is not, call out only a Samsung authorized servicer, as they will have the boards and proper tools to service this TV. Good Luck

I have a sony kp 48s and there seems to be a blue shadow on the picture?? i've tried everything in the settings to fix it but it just seems like a manufacture malfunction?

You probably need to get a Sony TV Convergence Kit. More information can be found using the link below.

Convergence Symptoms:
  • Screen Looks Distorted/3D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.

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

If the set cannot converge it self then the convergence ICs need to be replaced. Check local professional for prices

Picture shadow on rear projection Sony big screen TV

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

You have bad convergene output IC's. There are 2 in the set and we always replace them both because the one that s not bad will likely fail in ashort time causing you to have a 2nd labor bill.
