Re: tv double image

It's not only adjustment, you have to replace both STK 392-560 IC.

Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?

If you have a CONVERGENCE problem and it will not adjust---the two STK-392-150 Chips this set uses need to both be replaced and the set adjusted with the original remote control.

You can, if you are able to do the repair, buy a pair of chips for less than 14 dollars plus shipping on Ebay.

If you cannot do the repair--shop around your area--most shops are going to charge 300 or more for this kind of repair.

When you consider the cost of the parts--if you can do it or know someone who can--you can save the set and a lot of money--This repair can easily be done right in your home in about 1 hour--I know as I have done hundreds of them---did two today.

The chips (with the back off of the set) should be on two metal heat sinks on the board on the far left---they will be facing the front of the set.

All that is required to get at them is to remove all the plugs on that board and the screws that hold it in and tilt it up so the bottom of the board is in view---you unsolder both chips (about 18 pins each) and remove the 2 screws that hold each to a heat sink.

With 2 new chips you put heat sink compound on the back of each--it is a white grease to move heat quickly from the chip to the metal, and solder both chips in----put the board back down and all the plugs back(I usually mark all of them so I know where they go) and turn the set on and see what you have...

Most of the time this repairs the set--go into the customer menu and adjust the convergence and you are ready for another 5-8 years of life---this is the normal lifespan of these chips.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
