If you have gone into the customer menu and CONVERGENCE is skewed and will not adjust:

One or both of the two STK-392-110 convergence chips that this set uses are bad.

The chips are about 2 1 /2 inches wide by 1 1/2 inches tall and are black in color. They are mounted on metal heat sinksThe power went out and came back on, then the TV's - 2.gif with fins and are side by side--they will have the Stk-392-110 number printed on them in white letters.

If you locate them take a good look at all the light blue resistors in front of them--most are marked 2.2 ohms---look for any that are white or discolored in the middle---if you find one or more YOU HAVE FOUND YOUR PROBLEM.

BOTH chips and any bad resistors need to be replaced and the set adjusted. If you can do this repair you can save a lot of money as you can buy both chips (a pair) on Ebay for about 12 dollars plus shipping.

I have start to finish instructions for this repair on this type of set. Keep in mind, I am not allowed to post MY email address here for you.


If you cannot do this repair yourself, shop around your area--most shops charge 300-400 for this kind of repair--I do them here for 200-250 and have done hundreds of them.

If they say it has to go to the shop--keep looking as any good tech can do this repair in your home in about 1 hour.

If you have any questions or need advice reply to this posting here OR check out all my many solutions here for more information concerning what I have told you.

I am here to help people.

    SD Tech, I would like the instructions to replace the convergence chips and other possible defective parts. I repaired TV's back in the dark ages (70's) while I was attending college. I am not familiar with projection TV's so I am not familiar with the cables that go to the Hi-Volt trans and projection lamps. Is it easier to remove the entire chassis or just replace the parts while the chassis is still connected to most of the TV?

Double image from red bulb

Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synchronizing.
RP TV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Hope this will help in solving the problem....

Unable to align cross hairs on the blue lense. Dose the lense need to be replaced?

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 projection 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.

Here are some photos of convergence problems

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Yukon yd-100 lens removal for camera fitting seems like thred is broken

When you say lens, did you unscrew the eye piece or the actual lense? because the eyepiece is meant to fit your adaptor for 35mm cameras etc. but the actual front lense should be tightly sealed and thread locked to make your glass (scope) waterproof to some extent and to protect the alignment of the other lenses within your scope. If it is possible your local camera shop may have the ability to re-align and seal your scope, but if not do you have a warranty? and if not even that, if i were you i would align and accraglass your piece back together, it's a last ditch solution that should last for years.

Converge Problem

Replace the two STK392-110 Convergence IC's. I had the same exact issue and I replaced mine last night. When I turned it back on, i just went the two convergence options and it looks better than i ever remember!
