What you might be experiencing based on your symptom sounds like a damaged convergence IC.

With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is
http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try
http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.


I hope this information allows you to resolve this issue.

I have a digital Total Line thermostat that has a blue, white, yellow, red and green wire. Where do I attach these wires to the Model 44300A unit?


Normally Red to R (24v coming to stat) White to W (Heat) Green to G (Blower)
Yellow to Y (Air conditioning) Blue to C (common)
This is assuming you have gas heat and central air conditioning. If you have a heat pump blue would be for that. If you have a volt meter, check voltage between red and blue with furnace turned on. It will be 24 volts approx. if blue is common.

Try to adjust the digital array, if it is still bad the two chips will need replacing. I've had it done three time in 7 years at $300.00 a pop

Colors do not line up on my tv ( left side of sreen looks like 3D) digital array "+" are only white on right side.


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

I have a yellow line on the right side of my Toshiba 50 rear projection TV and yellow shadows around people


It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.

Colors off. blue and yellow not lined up


try to set the convergance if you cant you can adjust the color tubes from inside the tv but have to be very careful to do this. There is actually only 3 colors in the tv red, blue green so I would say your blue and green need lined up

Red color not lined up


You can try making adjustments to the convergence in the user menu. If they still will not line up you will need to have the convergence ICs replaces along with a few resistors in the convergence circuit. Fairly common in many rear projection TVs.

Digital Array?


Replace IK04 and IK05, both STK392-110, but use instead STK392-150's for greater reliability. And don't get some Chineese knock-offs - use original Sanyo replacements. If you don't know where to get those try ACME Enterprises in Florida,
http://www.acme-sales.net/index.shtml
Also measure the low ohm feed resistors in that circuit. However usually just replacing the convergence amps will restore normal video...
