TAKE OFF THE FRONT PANEL AND FIND THE FOCAS ELECTRONIC FOCAS CONTROLS. USUALY BETWEEN THE LEFT SPEAKER AND THE FIRST CRT GUN. PAUSE A DVD WHEN THE CREDITS GOING. OR USE A MENU IN YOUR SAT RECEIVER TO LOOK AT. USEING THE GRID IN THE TV SOMTIMES IS NOT ACCURATE. YOU WILL SEE 6 SMALL KNOBS (RED,GREEN,BLUE)FOCUS AND(RED,GREEN,BLUE)SCREEN DRIVE .FOLLOW THESE STEPS
1 TURNDOWN RED AND BLUE SCREENDRIVE
2 FOCUS THE GREEN (YOU SHOULD SEE SCANLINES)
3 TURN DOWN THE GREEN SCREENDRIVE
4 TURN UP THE RED SD UNTILL YOU SEE RETRACE LINES THEN BACK IT OFF TILL THEY ARE GONE.
5 FOCUS RED (UNTILL YOU SEE SCANLINES)
6 TURN RED DOWN AND TURN UP BLUE
7 FOCUS BLUE (BLUE WILL NOT BE AS GOOD AS RED+GREEN
NOW YOU ARE IN FOCUS, NOW YOU NEED TO GET SCREENDRIVE BACK
THE BEST WAY IS TO, PAUSE A DVD ON A BLACK SCREEN
SELECT PLAY MOVIE AND HIT PAUSE RIGHT AFTER . TURN ALL THE LIGHTS OFF IN THE ROOM AND USE A SMALL FLASHLIGHT TO ADJUST SCREENDRIVE SO YOU DONT MOVE FOCAS BY MISTAKE.
THE TRICK IS TO END UP WITH A VERY FAINT GRAY SCREEN WITH EACH COLOR UP AS FAR AS YOU CAN WITHOUT SEEING ANY COLOR ON THE TV. WHEN YOU GET THIS TRY PLAYING THE MOVIE. MAKE SURE THE BRIGHTNESS AND CONTRAST IN THE TV ARE AT A NORMAL LEVEL BEFORE YOU START . COLOR,BRIGHTNESS,AND FOCUS IS NOW SET TO YOUR DVD PLAYER.DO A FINAL CONVERGANCE AND YOU ARE DONE!
IF YOU CAN'T GET A COLOR TO FOCUS YOU MAY HAVE TO DO THIS MANUALY. SOME TV'S YOU CAN LOOSEN THE NUT ON THE CRT LENS AND MANUALY FOCUS IT. (LIKE AN OLD CAMERA). IF YOU GET THIS FAR YOU MIGHT AS WELL CLEAN THE LENS WITH A VINEGER BASED GLASS CLEANER (SPRAY THE RAG NOT THE TV) TAKE A LOOK AT THE MIROR, CLEAN IF NEEDED. IF THE MIRROR IS REAL DIRTY THEN THE SCREEN MUST BE BAD TOO.TAKE THE SCREEN OFF AND CLEAN THE BACK SIDE IF NEEDED. LOOK INTO THE LENS AT THE PICTURE TUBE YOU SHOULD SEE A NICE BRIGHT CLEAN PICTURE IF IT LOOKS CLOUDY YOU NEED TO CHANGE THE LIQUID IN THE CRT GUNS.I DON,T THINK YOU WAN'T TO TRY THIS YOURSELF.
TIP(I USE A LITTLE ARMOR ALL WHEN I CLEAN LENES, THIS REPELS DUST LIKE IN YOUR CAR) IF YOU CHANGE YOUR FLUID AND WANT TO KNOW WHERE TO GET NEW FLUID I PUT CLEAR ANTIFREEZE IN MY PIONEER TV 3YEARS AGO AND STILL LOOKS GREAT "NOT KIDING"
HOPE ALL THIS YOU. IF YOU ARE NOT COMFORTABLE TO DO IT. HAVE IR SERVICE. REPAIRING THIS WILL BE YOUR BEST OPTION>THANKS
Auto Focus button no longer work.Tv have a problems known as a convergence problems,it dead.Tv have colors lnes R,G,B mis alignment,have colors shadows 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,must be replaced on the tv convergnce board to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.
Most likely this set has bad convergence ic's and some open resistors. This is a common problem for projection tv's.
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
I hope this helps. Thanks for using fixya.
There is a convergence output kit for this set. There are probably resistors in the convergence circuit that are starting to loose there values. If you are going to have the set worked on have them install the whole kit which includes the convergence outputs and resistors. Thanks
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
This sounds like one of your convergence IC's has burned out. There are 2 IC's in the set and the one that handles RH (Red Horizontal) has stopped working. The IC should be replaced and the set realigned by someone with experience.
Your convergence output IC's have either shorted out or opened up, either way they will have to be replaced and possibly a resistor or two. One distant possiblity is the DCU or the Convergence Yoke, but most likely the IC's. You will probably want a tv repairman to do the repair as there is some soldering to do and some paste/ IC's to install/ calibrate. A repair like this could run from $300 - $500 for IC's depending on who does the repair, The Yoke or DCU would cost a couple hundred more.
