If your talking about the sets convergence does not line up and it looks like a 3-D picture than The best advice I can tell you at this point is to go to tvrepairkits.com 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! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
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!!!

We cannot get the color to align. It appears like there is a blue or yellow background around words


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Colors are separated on the top from the left to right


Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.

TV automatically turns magic focus mode on when the power button is pressed on the remote and even manually.


I have this problem starting today. Unfortunately, others who have fixed it have done the following.

* Unplug TV for hours and it worked

* Buying manual switch to the outlet or surge protector and switch power off that way.

It appears that I'm in no mood to spend hundreds to get this fixed for hundreds of dollars and just going the Radio Shack route of buying a switch which would probably be more of savings. But needless to say, I hope that is the only problem I have.
