Go in and find the conv ICs, they will be mounted on a
big heatsink and the wires going to the conv yokes will
most likely plug in somewhere closeby.
Conv ICs are the workhorse of the CRT RPTV, and it is
not unusual at all for them to need to be changed out
at some time in the life of a CRT RPTV.

PS -
The wires for the conv yokes at the CRT necks are the
thin ones. The thicker ones are for the hor and vert
sweeps, which must never be disconnected from their
circuitry during CRT operation.

If your beam loses sweep on any of the CRTs, it will
instantly score/gouge your phosphors on your CRT faces,
vaporizing the phosphors there and ruining the CRTs.
The beam is very powerful, but in normal operation
moves incredibly fast, not damaging anything. Any
slowdown of the movement of the very powerful beam that
draws the picture, acts like the searing vaporizing beam in Tom Cruise's War of the Worlds.

I have triple vision going plus it has started to


This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly.

Apex out of convergence


I have this TV and have fixed this issue. If you cannot adjust Red or Blue convergence, then your STK ICs are defective. The signal board or Digital convergence board is not able to adjust sig lines on the deflection board so pushing buttons does nothing. The STK's are your amplifiers for vertical and horizontal. This will require dissassembly and soldering. You'll need 2 STK392-020 IC's and 125v/5A pico fuse or buss fuse..

The STK's are mounted on 2 massive heatsinks. Can't miss it. Word of advice, LABEL the 3-4 Pin plugs B,G,R from left to right. These are your Vertical and Horizontal coils for each tube. Don't mix them up. I did and the tv survived luckily. Chances are if your STK's poped, then they took out the -25v line. Take out the power supply that is mounted vertically on the right. Look for a row of axiel lead fuses with "SOC 5000" printed on it. They look like white rectangular blocks with leads. Check them all. Particularly RF817. Sits next to RF814. The service manual lists it as a fuse and NOT a Resistor-Fuse like the label suggests. I found more than one typo like this. I replaced mine with a generic 125v/5A fast blow buss fuse. Soldered in a holder for it. Should work the same.

Took me abit to realize it was a fuse on the power supply. This -25 line traces to W057/W058 next to the first STK chip. Explains the symptoms.

Bowing at top and bottom, can't adjust convergence replaced IC


Your TV most likely has one of two 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.

Replaced ic's but green is still seperated from the blue and red


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Suddenly double/triple images, bowed red at the bottom


Yes, the convergence IC's need to be replaced. If you are not experienced in TV repair, I would recommend getting a qualified repair man to do it for you.

Here is a link with instructions on how to do this, if you feel adventurous:

Problems after new ic chip install


Did you check for open resistors in the convergence circuits? Often that is what happens when the old ICs wear out it will cause a couple resistors to burn open, and they show no outward sign of being bad. Also double check the IC pins connections for solder bridges thats another common problem, I always use a magnifying glass to double check my solder when ever I do convergence or any IC work where the pins are close. But with the streaks youre describing I would think maybe resistors.

Red convergence is bad.


Hi, you need to change the convergence ICs , STKs: and some resistors,low values; , after changing them, you will have to go into the service mode, to do some adjustments.that's it.

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.
