I have a samsung dlp Model no. Pcn5425r The problem I am having is that the picture is all distorted with curved edges and blurry doubled images. I thought it was a convergence problem so I replaced it with a new part...but it is still doing the same thing...I am guessing it is maybe the color wheel? But I don't have the whistling or loud noise sound as described by some who have color wheel problems...what could it be..should I try replacing the color wheel too?

You need to replace your color wheel. Part# BP96-00674A. This has been a common problem with the samsung dlp's. I hope this helps.

Hi Ian
What you are suffering is something called barrel distortion which causes images to appear spherised or "inflated". Barrel distortion is associated with wide angle lenses and typically occurs at the wide end of a zoom lens. The use of converters often amplifies the effect. It is most visible in images with perfectly straight lines, especially when they are close to the edge of the image frame

the way to solve it is to try not use the end of the of the zoom of your lens. Above 20 mm you should be fine. If this is not possible then you can correct the effect in programmes like Photoshop

Hope this helps

The tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

Projection TV sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

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

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking video
• White looking video
• Halos around objects
• Red/Orange looking video

You can see some examples and find a fix here...

make sure you do not have anything sitting on the top of this tv. I have seen this on my tv by just gently putting pressure with my finger on top the screen starts to curve up at the edges.

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

The convergence IC's are definitely bad. They are not a plug-in device, they solder in so this is a big job.

Can you reply to this post and verify which model is your TV?

learn lip reading..... but really 1080i inputs have to cut main circuit and be processed through your main amplifier .
shorted or too low a signal at input is a start.

I had noticed your question before posting mine, since it appears no one had given you a solution thought i would share the solution given to me. Two different techs told me the same thing it would need a new convergence board. I ordered my board today hopefully have fixed soon as it arrives. I noticed your question has been hear awhile but thought maybe if you still needed some help I would share. It is going to save me $300 doing it myself, but if you are going to try make sure to talk to one of the techs first on live chat. Goodluck
