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?

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

SOURCE: double image shows in red

it is quite fixable and usually in your home; it is called convergence--kp57wv500 uses two STK 392-560 convergence Ic chips; both and any bad fuses or resistors around them need to be replaced and the set adjusted after.

I fix a lot of these sets in my area---if you call a shop you will pay 300-400----a lot of independent people will do it for under 250 in your home--shop around--now is the slow time of the year for tv shops---you could buy both IC chips on ebay for less then 13 dollars plus shipping---this is a normal problem in all projection tv sets--the chips have a white grease on the back of them designed to transfer heat--after several years it drys out and one of them goes bad---repair should take about an hour or so in your home---you should ask yourself if 200-300 dollar repair is worth while, could you replace the set for this? If the chips are replaced and the set adjusted they should be good for 4 or 5 years at the least.

I do this here for free so if this has been helpful give me a vote here. If you have questions or need more help here is my email:

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.

If you need assistance or have questions let me know--I am here to help people.

You have a problem in the convergence circuit. Most likely the stk392-110 ics need to be replaced (with stk392-150's or better) and you are likely to have some burned resistors in this circuit as well.

This really is not a repair that an amateur should attempt, although it's pretty straight forward for anyone experienced with repairing big screen sets. Our shop charges about $300-350 for this repair in your home.

Cracked screen and down screen


If the double images are located at the bottom on one side, you might have cracked the mirror inside the set and it has been displaced making the picture in that area bad (especially if the rest of the picture is OK)

some of these tvs have internal adjustments for everything including alignment which fixes the double image problem. if you remove the cover you will find a lot of little adjustment dials. you may find that they have symbols that show what the adjustment is for. if you want more info. email me at sb1216us@yahoo.com
