Red snowy effect, and words are very blurry

Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

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

There is almost nothing that can be fixed by yourself if your not trained in high voltages and advanced circuitry now days. This sounds like it could be your color guns going bad or the power supply.
This set also has an issue with The tv convergence board,require 2 STK convergence ICS and some or all it resistors to replaced to solved the tv convergence picture problems.

The tv have a problems known as a convergence problems,it dead.Very common problems on DLP projection tv.R,G,B colors lines mis alignment,colors shadows and 3D pictures.The problems is the convergence board parts the 2 STK convergence ICS and some or all of it resistors are dead.These parts must be replaced on the convergencce board to solved convergence problems.The shop will cost u $300-350 for parts and labors.

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

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

How can I fix it? The magic foucs goes to two or three lines and goes back to the picture. The sides are blurry, like red and green.

Good Day;

Sounds like you have bad Convergence Output IC > 267P155010 > STK393-110, replace and it will correct the problem TV uses only ONE, make sure all resistors look good in the circuit around IC.
Good Luck, big IRISH.

A halo effect usually means the coolant in the CRTs need replacing in the effected color usually blue goes first followed by green. red seems to be less prone for some reason.

sounds like 2 different problems here. first problem sounds tuner related. second sounds convergence related. third issue (cost effective to repair ?) at this point i would replace the set. i hope this helps
