THE PICTURE REVEALS SHADOWS IN RED AND BLUE OUTSIDE THE CENTER OF THE SCREEN. I KNOW THE GRIDLINE PATTERN IS AVAILABLE TO TECHNICIANS FOR SETUP, BUT YOU NEED TO PUSH THE SEQUENCE OF BUTTONS FOR ACCESS. DOES ANYONE KNOW THE ACCESS CODE? THE TV IS COVERED BY ANY WARRANTY.

Re: THE OUTER EDGES OF THE PICTURE ARE BOWED .
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.
If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fiTHE OUTER EDGES OF THE PICTURE ARE BOWED . - 69189a5.pngrgence your need to fix it. See below for a fix
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Green really shouldn't be adjusted, you adjust red and blue to the green. When a color is bowed that indicates that a part or two are bad, probably the convergence output IC's and possibly a fuse or fusible resister. You may need a tech to come adjust it for you because after replacing IC's the adjustments should be done in the servicers menus not just in the consumers menus.
You need to replace the convergence Ics located up front behind the speaker grille numbers STK392-110 you can get replacements at the following link and they provide free tech support and instalation instructions with pictures. heres the link. http://servicemanuals.vstore.ca/
Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
