My Samsung HCN653W 65-Inch Widescreen Projection HD-Ready TV has a 3d like picture when it has been on a hour it goes back to normal


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) 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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
  • 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.

Blurred picture red and blue shadows


Hi,
Please run the convergence feature on your TV. Its giving you double image because the red, green, and blue guns are dis aligned. By running convergence it will realign the guns properly. You need to run the convergence feature at least once a week. Please note this is only for CRT rear projection TV's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to refer to the manual on how to go about it
Good luck!

The red and green colors are sepperated from each other and can't fix it thru the remote.


This set uses two of the STK-392-120 OR -110 CHIPS FOR THIS PROBLEM.

BOTH and any bad protect resistors will need to be replaced, total parts cost on EBAY under 25 dollars.

I can tell best way to get at them and do the repair--it involves soldering as each chip has 18 pins and is soldered in.

Chips (viewed from back of set) should be side by side on metal heat sinks with fins.

See attached photo of typical convergence problem.

Bottom 4 inches of my mitsubishi 65" rear projection tv is distorted. it seems like the colors aren't correct in this area. the rest of the picture is great. Justin


LOOK AT ATTACHED PHOTOS AND TELL ME IF THEY LOOK FAMILIAR.

THE MODEL INDICATED USES TWO of the STK-392-570 CONVERGENCE CHIPS.

I have step by step, start to finish instructions for this repair in this set. It involves getting the middle circuit board out of the set and replacing the two chips.

Total parts cost on EBAY WILL BE UNDER 25 DOLLARS AND repair takes on average about a hour--I have done hundreds of these sets and if you are doing it for the first time it may take longer.

The instructions tell you everything you will need and how to do the repair from start to finish and they are free.

If the information helped you, rate this solution as "very helpful: as I do this here for free.

If you want the instructions let me know and I will post them here for you for free. I will assist you from start to finish if you attempt the repair.

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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - 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.

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 solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
