Go to the convergence screen on your settings and adjust with the arrows to the box showing in the middle of screen. This just happened to me thre a lightning strike and will work and its easy.

Did you attempt to repair your computer on your own and then started to have this problem or did this just suddenly happen? Also, can you post a picture of what you are seeing?

My hitachi 50v500 has double letters/numbers... picture doesnt seem to be alligned properly? Everything has a matching shadow just to the left.


I am answering this because I know this set and do not like the answers you have received.

If you see a slight "ghost" to the left or right of lettering--it can be corrected with the remote--there is a exact way to do this--I have done it before and have instructions based on a service bulletin from Hitachi.

Confirm you have the ghosting to right or left of letters and I would be happy to post the instructions to correct that--all of it is done with the Hitachi remote that came with the set.

If you decide to do it I will give you the instructions and help you do it.

I have helped 4 other people here with the exact same set and problem.

Understand that not all people here know what they are talking about-I am sorry you got a poor answer, but I know this set well.

You want to fix it for free? I can help you.

Keep in mind I am in California and possible time differences.

Regards, SD TECH

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

Looks like 3D Picture


You probly have a convergence cicuit failure. Replacing the convergencr IC's will probly fix it.
I recommend a professional repairman to
do it though. Particularly if it needs further adjustments after the IC's are replaced.

JVC AV-56WP30 red "shadow"


The problem called Convergence problem. Unfortunately, some sets have manual convergence boards - which means you can do nothing but replace it and adjust the manual controls on the board itself. But some of the newer ones (Maybe yours) can be accessed through a service mode. So, give it a try and look for a service mode in your set... Good luck!
