My big screen Rear Projection Television set is blurry.

Factory setting will not cure a convergence problem---in customer menu look for convergence and see if it will adjust---if not and looks 3d etc parts have to be replaced and set adjusted.

There are kits for this available on the internet by brand and model number.

May or may not be a do it yourself repair depending on what skills you have.

hi,
ur tvs focusing side have some complaint. replace crt base sockets( three of them at a time). and check it.
ok

It is unusual for a rear projection to be out of focus since the projectors are fixed. But, it is common for the projectors to be out of alignment, in which case the picture will look like a bad 3D movie of yesteryear.

Go to the setup options / menu, look for the ALIGN option, follow instructions on screen.

Ur convergence is dead,need convergence kit.
U know how to solder right?Tries these websites for convergence kit.Tv Repair World.com,Shopjimmy.com,Ebay.com or Partstore.com

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...

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

there is a focus control in the front of the set behind the front grill there is a door in the middle attached by screws take this off and it should be right behind it. There are six controls on a little box one row says focus and the other says screen don't adjust the screen controls. In some cases these are in the back of the set.

It sounds like you have moved the mirror, turn it on and try to see if you can realign it. KEPP YOUR FACE OUT OF THE LIGHT PATH.

i got a zenith tv and the picture is really blurry how do i focus it ?

1)Remove rear cover = clean RGB lens with soft cloth
2)Remove front speaker grill cover and access panel
Locate screen / focus block = adjust RGB focus controls
3)Last,if needed, unlock each focus lens cap = adjust then lock

it sounds like the focus block or flyback is bad.sometimes you can put nail polish on the adjustments controls to make it stay.usually they are marked from the factory with white marks check and see if they are aligned.but be sure somebody with tech-skills help you.the flyback usually has a screen & focus control.(the big red wire to the tubes or block)
