SOURCE: Sony KP-43HT20 ghosting effect.

I got one likes that. I have fixed mine by changing only one IC 8001. After my TV operating about 20 days, the problem come back.It might be the quality of the IC STK 392-56. Because IC production made by Sanyo ???

SOURCE: Screen Flashing

In a Sony TV, the most common cause of the picture flashing on and off is a weak picture tube. When the set was new, it took about 5 to 10 seconds for the picture to appear once the set was turned on. This is normal. If you have been noticing that it has been taking longer and longer to first appear, this is the clear signal that one of the picture tubes is getting tired. There is a circuit called IK Blanking that monitors each picture tube and adjusts them as the tubes age, so you always see a good picture. When one of the tubes has weakened so much that it cannot produce enough brightness in the picture, the circuit shuts the picture off completely. I guess Sony does not want you to see a tired, dull picture. When the tube is right on the edge of being too weak to keep the picture on, the picture will flash on and off, and it will also take much longer beofre it first turns on. The good news is that the Sony picture tubes always respond beautifully to reactivation (CRT Recharge) but you will need a qualified tech familiar with Sony projection sets to handle that repair for you.

two three-pin voltage regulators near the left side (looking in from the back) bend over from the heat and short to a ground rail. Check and straighten them with the power off and the unit unplugged

Your set uses two STK392-560 convergence ICs they are attached to a large heat sink on the D board. You can save your self about 400 for a twenty minute repair by getting new ICs at the following link as trhey provide free instalation instructions with pics so you can do the job yourself. It only requires basic soldering skills I would order about six 4.7ohm 1/2 watt resistors as well just in case you need them asusually sonys' will burn one or two of the 4.7ohm convergence resistors when the ICs fail. Heres the link

SOURCE: Sony KP-51WS500 Rear Projection TV colors are distorted.

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.

You have a convergence issue, will have to check convergence IC,S or just replace them there are usually two of them mounted on heat sinks they are usually STK'S with a number after. Also must check fuseable resistors supplying +15 and - 15 volt s to the chips. After replacement some convergence alignment may be needed. Good Luck.

Blue convergence is off right will not adjust


Hi. there is a malfunction that has occurred within the convergence chip that is located on the PC board(demod). this is a Hybrid chip that controls the calibrations of the RGB streams. If this chip becomes unstable, it will not allow proper calibrations.

Replacing this failed chip will fix this issue.

The actual sony chip is not available at this time but, there is a compatible chip that will work with your set. i will post a link to the affected part below.
