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
problem with unit is convergence-find that in the menu-try to adjust red untop green then blue ontop green.if they will not adjust gonna need parts-try to adjust it .if you need more help please list the model number
This is a convergence problem that can be as simple as poor connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself.
Let me know if you wish to attempt the repair and I will post additional details and instructions.
Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, pico fuses, etc. Everything you need to fix it yourself. Its an easy fix.
you need to replace both convergence ic's they are located on your D board mounted right on the 2 big heat sinks you should either need STK-392-560 or STK392-510's you can find which one on stamped on the side of your old ic's. you can go to this sight and get them at reasonable prices plus picture installation instructions and free online tech support if you need help. By doing the repair yourself you will save between 4-500.00 for about a 45min repair http://servicemanuals.vstore.ca/
First, this assumes nothing else is going on to cause it. Here's what I did. Go to the 'green grid' via the v76 menu and go through the alignment there. Notice that there are red letters, blue letters, and a green grid. While you are in this screen, adjust the red, green, and blue focus watching the individual color's item until they are in focus. If they won't focus here, they won't focus and you have something else wrong (what I do not know). Then, return to normal programming, then select menu on the remote, then screen, then adjust projection tv convergence both horizontal and vertical crosshare. That ought to get it.
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.
Sounds like the green is out of focus.
If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube.
On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus.
Hope this helps.
