Got new STK392-040 chips and picture is still distorted. Manual convergence still won't alligne all colors.


the 183 is entry into the tech menu===you need to test all the low value resistors around the convergence chips(only 6 or 8) and they will read low and a resistor with NO reading may be your problem.

Also these sets use a pico fuse going to each chip--either right with it or back at the source----know what a pico fuse looks like"

Green & Blue Ghosting Convergance problem


Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

Color ghosts out of allignment


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.

I have a 3 year old mitsubishi wd-52526 lcd projector tv that is starting to have some focus/image alignment issues - in general picture is a little out of focus and there are rainbows around things at the...


the differnt guns are out of alignment. Your tv has 3 lcd screens, a red, green and blue one what overlay to form the image. Sometimes they move slightly for what ever reason and that causes the rainbow and out of focus picture. Its something that a trained pro should do but is a cheap fix and won't set you back too much

1215 hp photosmart printer


I solved it! I bought a new Epson 3 in 1. Funny thing; I have a "FREE FER TAKEN" box just inside my shop, people come in all the time to check it. I put 3 HP ink jet printers in there almost a year ago and nobody wants them.

Hotachi 60 model 60fx32b


I hope thats a typo and you meant 2 (two) inches on the left side. Have you opened the small door on the front and hit the "magic focus" button yet? NOTE: be sure to turn on the set and let it run constantly for 20 minutes before pushing the magic focus button, once it starts do not push any buttons it will go through all 3 colors and stop on it`s own when it`s completed, if you don`t have bad IC`s this will fix your problem, good luck

Hitachi 61SDX picture got dim shows Code 3


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.

Canon Digital Rebel XT Bulit-In Flash Strobes in Low Light


use more light:)
its very normal that it does that. it dosent get enough light so it cant focus. the only way it can autofocus is that it stobes the flash to adjust the focus automaticly. use an external flash like 580EX and u will get an focus asisten thru a red grid throne by the flash unit.
