Everything looks like a 3-D movie!

Turned on the set one day and the images are sorta color separated and it looks like a 3-D movie without the glasses on; any ideas what this might be?

Replace convergence IC's IK04 = STK392-150 and IK05 = STK392-110. Also check resistors RK42,RK46,RK50,RK54,RK58,RK62 for burnt/discolored.

How do i play movies on my i pod

We picked up an iPod Photo the other day, and most observers have asked us "Can that thing play movies?" The short answer is no, only music and photos-but the longer answer is "sorta, but not really anything worth calling a movie". In this week's how-to we'll show you how to "play" a movie on an iPod Photo by exporting frames of a movie, importing them to the iPod and playing them manually by click-wheeling through thousands of images, or even viewing 3d views of objects. Pointless? Yes. Will a lot of people try this and put movie trailers and **** on their iPod Photo.

Strong colors, specifically those in the red

it seems you are experimenting a light engine problem.This is how your tv works: So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact maker or look for your light engine online.

Distorted image and color separation and overlap

Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The best advice I can tell you at this point is to go to and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

sorry i am new at this but have had the same problem with a toshiba and it was the IC chips which control the converigence which is lining the colors back up

Im seeing double on my 36inch Mitsubishi projection!

Do the colors seem "separated" somehow?  Sounds like the projectors might have become misaligned. Has the TV been knocked by pets/children/spouse?

Picture Looks Like a 3-d Movie

This is bad convergence. Try self focus and if still not ok is hardware problem. The STK are leaked and need to be replaced. It's not easy, you have to remove the all deflection board and for sure you'll have some resistors to replace too. I sugest you to call a tech, but first try the self focus.
