I'm sorry for the difficulties you're experiencing in viewing the pictures in full screen. Please set the Aspect Ratio Settings on the TV to Aspect Ration 1 as shown in the below picture to resolve the issue.

Thanks for understanding. Please let me know the devices connected to the TV and history about the issue if it persists.

This model uses two convergence IC's----if 3 D one or both are bad.


Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.

Both chips and any bad protection resistors around them need to be replaced and the set adjusted.

If you are able to do the repair yourself total parts cost will be under 30 dollars.

Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.

When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.

After some years the grease dries out from the heat and one of the chips goes instantly.

You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--

If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.

If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.

If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.

IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know

I can tell you what you will need aside from the parts and how to proceed with the fix---

If all this helped rate this solution---I do this here for free.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Regards, SD TECH

you may have a dead or bad color gun. go thorough the convergence routine and see if all the colors are there. If your missing a color, you can purchase just that gun but I would advice that your replace all three. Be aware that this can be costly and in some cases you may have to purchase the whole pc board with the three color guns on it, depends on the model.

In a nutshell, the convergence ICs have failed. The cost to fix by a service company is likely about $300. You may find someone who does it on the side for around $150.

If you are happy with the picture, you like the tv, then $150 might be worth it.

It is possible to do this repair yourself if you have an electronics background.

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. Repair kits with instructions are also avail from www.TvRepairKits.com

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.

Picture of a set that needs the fluid changed.

A pop means that a component inside the tv has failed the big way - it has exploded. The red button that blinks is the status light - it signals that a massive short has been detected and the power source of the tv has been forcefully shut down. The clicking comes from the source, it keeps trying to start so the protection system keeps shutting it down.
The failed component will have to be identified, replaced and the rest of the tv tested to check what other damage has occurred and fix it. This is a job for a pro, no way you can fix that yourself. Unplug the tv from the wall - leaving it powered only makes the damage greater - and call one.

Hi,

When you turn it on, does the red light sort of pulsate on and off?
Do you hear any odd sounds (a squeal, perhaps, as the red light flashes) coming from inside the set?


How old the unit is?

Let me know,so that we could proceed.

Hope i helped you.

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