SOURCE: Ghost images

I just got my ghost problem resolved by getting a technician to come by and all he did was to reconverge my TV.
The pictures are much clearer and the ghosting images seems to have been corrected.Give it a try and yours should be good again.

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:

Can I rectify the problems below, #'s+letters"r"doubled(ghosting)


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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 note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Sony Bravia KDF-50E2010 LCD Convergence Problem


Well this is the fix for the usual Ghosting problem....

To bring up the "service" menu, put the TV in standby mode, then press in sequence :

Onscreen Display ( the little screen with the i+ in it )
5 ( channel number 5 )
Volume Up ( upper end of volume button )
Analogue ( middle top button )

The TV should switch on and when it's warmed up, you should see a screen with lots of big green lettering on it.

Press the "menu" button ( middle bottom )

Use the direction dial to move down to "LCD Drivers" and press right on the dial to enter this menu.

Move down to "S H Pos Reg R". It should be "10", change it to "11". ( Left/Right to adjust )
Move down to "S H Pos Reg G". It should be "10", change it to "11".
Move down to "SHPos Reg B". It should be "10", change it to "11".

Press the menu bottom to drop out of the menus, and the standy button to drop to standby. Switch back on, and hopefully your ghosting will be gone hope this works davy mac

Red Ghost


This may be a convergence issue but it is difficult to determine with that description. Watch this video and see if it will help you determine if you have a convergence problem or possible something else.

Half the screen has ghost image (not focused)


Replace the convergence ICs. They are located on a large aluminum heat sink with STK numbers stamped on them. They cost about 10.00 each. They have to be soldered in. Let me know if you need anything further.
