Yes, it is repairable but if you keep forcing the set on then chances are you are going to make matters worse to many people wait untill the TV will not come on resulting in damage to more Parts Right Now if you know how to solder you need to resolder the power supply board and if the STK ICs have never been replaced ,they am sure are due to be changed STK392-110s use the 120s. Mats Electronics has them $9.95each 1-800-628-1118. You need to have this matter tooken care of Soon. See if the ICs just need to be resolder also,before replacing them.

Find a local TV repair shop. They may have one or know of another TV shop that may have one.Thanks for asking and show a few hands of support!

This thing weighs 250 pounds,had this big bulky DLP tv before for 5 years,gave it to good will,because it big and very bulky.Plasma and LCD tv same size weighs only 50 pounds.

fault in the convegence sections, can be related to the board, the lamps or the adjsutments.
you must check them one by one by elimination.
First of all when the set is warm and ON for few hours if the picture moves away the fault is in the convergence but if the fault remains entirely all the same throughout then you must set the lamps to focus and converge with the help of test signal, the colour puriity/white balance must be correct.

Replace ICs STK392-110s use 120s or 150s Mats Electronics 1-800-628-1118

Replace Both of the Convergence ICs they are big black ICs and will have Part # on them STK392-110s use 120s or 150s better ICs
Mats has them for 9.95 1-800-628-1118

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

The tv have a problems known as a convergence problems,it dead.The tv have colors R,G,B lines mis alignment,have colors shadows or 3D pictures.The tv convergence board,the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced to solved the tv convergence picture problems.The shop,will cost u $300-350 for parts and labors.

No,you might just need to Clean Mirror and Top of all 3 Tube Lenses, this Set does not have Lamp ,it has 3 Picture Tubes RED/Green/Blue. You might also need to adjust the screen drive Controls to each Tube.

Replace the STK ICS They are big Black ICs will have PN# on them STK392-110s use 120s

Hope it is just cleaning take off the front screen. I think on that model remove the speaker covers, and a row of screws holding the bottom of the screen remove them. Watch the wires to the front buttons there may be a connector or two to undo. Carefully lift up and toward you WATCH THE WIRES. With a dry clean cloth wipe off the three CRT tops and the back mirror. Put back together and see.
If you still have a green hue.
Remove the screen again. With a flash light look down the CRT's if they a real cruddy down in the coolant yes there is liquid coolant in them. The red doesn't have this trouble but the blue and green can get contaminated. Also look for leaking of the coolant down on the boards. There are procedures to clean and repair leaks. Let me know.
There are a couple of focus procedures which I don't think is your issue.
Good luck Mark

Hi,

You have a convergence issue, first see if they will move manually in your menu, they should be able to move up down left and right, and if not this is when two chips labeled STK392-xxx Failed. They can be located by finding the largest heat sinks in the unit.

Along with the possibility being an open resistor and or open fuse in the convergence circuit. All of the resistors around these chips should be checked pay attention to the ones that are standing up and they all should read low ohms, If they are in the k ohms they are probably open which is bad ,This is a tricky repair, if you have Never done this repair I don't suggest it friend.

But if you are willing to tackle this problem the only step by step procedure I found for you would be to watch someone do the repair, and this I found on the internet in the convergence problem screen. This will give you an idea of the work involved and also what the parts look like :-

You need to replace the STK ICs use STK392-150s and CK these resistors RK50 3.3ohms RK54 1.8ohms 1watt
or just order Kit#CZ0043
Mats Electronics has STKs 1-800-628-1118

A replacement remote is available here:

Hi,

This is a convergence issue. By making adjustments in settings, this would not solve the issue. You need to change the Convergence IC.If you want to repair it, revert and i would be glad to guide you.You need to have electronics experience, should know to read schematics ( if required ), could use multimeter and soldering iron.

**Please understand that by opening a TV you are exposing yourself to many dangers, including electrocution. Be sure that the set is un-plugged and keep one hand behind your back whenever possible to avoid a shock through the heart as this CAN KILL YOU. If you have zero electronic experience I would not attempt this repair.**
OK, public service announcement over.



The components that do that job are called "convergence" circuitry. The usual components to fail are the "Convergence Amplifiers" which are usually a pair of Integrated Circuits mounted to a large heat sink. (STK-392 or STK-394) may be printed on the IC along with some number such as 110, 160, 120.

Below is s a walk through on a Mitsubishi, this applies to Hitachi as well, they all use the same chips and circuits, you will at least be able to see what is involved in the repair.

Also look for burnt resistors around these components, as it is common.If the problem is isolated to only one color the replacing those STK amps and any burnt resistors will fix it. If all the colors are out of whack (Red, green, and blue, like a 3d effect all over) then you are likely looking at a fuse gone bad in the voltage supply to those amplifiers. Usually Sony or Mitsubishi have these fuses. The fuses (called "pico-fuses") are generally orange, or green, with no color stripes like resistors have.



You can look up these parts online easily with the exception of the burnt resistors and fuses which you usually need a manual(which you can also purchase online). The STK's price will vary from $15-$90 depending on which one, and the resistors have to be of the metal oxide type so as not to change value with heat.

One place to get parts is www.partstore.com

You could also get the IC's from even radioshack or Fry's.



If you want a professional to repair it, be prepared to part with around $300-$400.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Is picture 3d looking? Blue or red shadows around faces or words?


This is a convergence problem: let me know if it looks like your problem or comment here with more information and I will help.
