Dust it first with a dry microfiber cloth, then using the smallest amount of water, go in the direction of the screen grain. Go slowly and dry with paper towels.

Hi mmoir333,
If the symptom can't be fix by convergence set-up from the tv through your remote control then the trouble is internal and it is caused by bad convergence board. The most commonly faulty parts in this board is the convergence chip/IC. Once replace by IC/Chip your unit will back to normal again. Also you have to check for open fuse/fusible resistor in line with its power supply. Bad solder joints will do the same problem, I would advice you to re-solder first on that board and spot some cold solder.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work internal if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.



Hope I helped you.

Have a nice day!

Thanks for using Fixya.

usually you need to remove the speaker grille then you will notice a few screws in the lower screen frame remove thos screws then grab the screen frame and slide up wards to disengage the clips that hold the screen assembly on.

Goto TV Repair Kits website..and look on their Tips page for DCAM instructions....

For everyone else with this issue here is more info...

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 pics of convergence problems.

Common 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.

hello my name is rico, you have bad convergence problem. you need to replace the stks inside the tv, and look for colder on the boards. you gonna need a gun solder, solder, chawick, 2 stks(look in the tv for the number loooks like stk392-120 o something like it) look for bad fuses. that should fix your problem. if you need more help let me know at 602-810-7149.

Tries websites like Amazon.com,Ebay.com to buy a pack of clothes call the Miro Fibers clothes.Use these Micro Fibers clothes,with some water clean the picture screen panel.These clothes are not adbrasive,it for used to clean like eye glasses and exspensive camera lens and for shinning and buffering expensive jewleries.

Hitachi 61SDX01B... | Answered on Nov 28, 2010


Unplug the set from power.

Best way to do this is with back cover removed look for the three large black lens--they are the light source for your picture. This is a 10 minute job---do not touch anything else inside even if set is unplugged.

Clean with either a lens cloth or a paper towel with glass cleaner sprayed on it, This should be done once a year---if moderate or heavy dust, picture will be darker and duller looking.

The set has a mirror but that is more difficult to get at and it hangs at a angle so dust does not get on it.

What you have to do is remove the front screen assembly by removing the screws loacted at the bottom of the screen frame just under the frame lip. Lift the screen assembly up from the bottom to disengage the holder clips at the top and set the screen assembly to the side. On the inside of the screen, the part that faces the projection mirror assembly you can use some Windex and paper towels to clean the surface. On the outside do not use Windex as this will breakdown the protective finish used on the viewing side of the screen. To clean the viewing side, use a special cleaner also used to clean computer display screens. Re-install the screen assembly and you are done.

Possible loss of CRT heater line.

Hitachi 61SDX01B... | Answered on Apr 19, 2010


Using a lint free cloth, such as a diaper, and windex (no ammonia), spray the cloth to dampen it and using a swirling motion wipe the screen. Finish with a dry lint free cloth. Never use paper towels, and never spray the screen as the liquid can migrate between the different sections of the screen. Let me know if you need more help.

If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. Your symptom sounds like a damaged convergence IC.

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, heat sink compound, and some basic soldering skills, you can repair the television yourself.
*** VERY IMPORTANT NOTE***
If your set is not producing a clear picture and the colors are not lining up, do not continue to watch the set as this can lead to further failure and possibly damage the individual CRT’s in the set.
I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.

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

How do I tell if the IC’s are damaged?
Since you cannot look inside of an IC, you will have to locate some of the components in the area around the convergence IC’s. You may be able to see some resistors that have changed colors or you test a resistor and it no longer reads the value marked by the color bands or the printed value. You will have to replace the IC’s and the supporting components.

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 insulator for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.


Where are the IC’s located and how do I find them?
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/ , they do carry OEM or better parts. When you order from them you will get a kit with instructions on how to do the repair, step-by-step.

If no sound in all input, check the surround board. Is the audio distorted or on and off before? if so replace surround board :)

Contact me via email--you may have a bad cap in this set--it is location C707--if it is gone there will also be a 2 amp pico fuse blown---I can tell you where to look for both parts and what they look like--if the fuse is blown it is 99% chance just it and the cap are bad--very common in these sets--about 5 dollars for both parts together--each part is soldered in with two leads---I have fixed a lot of HItachi big screens--if you locate the fuse and it is gone the cap will also be bad.....

There isn't anything you can do yourself for this problem, but it should be worth having a qualified technician look at it.

Hitachi 61SDX01B... | Answered on Sep 09, 2009


It sounds like your fluid in the color guns is contaminated and you need to have it changed.

Hitachi 61SDX01B... | Answered on Sep 03, 2009


If the TV still has a good picture then yes. Have the Tech replace the IC's with the Sanyo Type as they are a better quality IC. They cost about $30 each as opposed to the generic for $10 each. He should also make sure there are no resistors in the circuit that may have changed value.This could cause the IC's to go bad prematurely.
