Hi,

Based on your general description, it could be:
1. loose connection or cold solder on any of the connectors and/or boards specially those related to power;
2. heat related - at some point, the heat generated inside the unit could cause a component failure or worsen a cold solder/loose connection;
3. a component is about to fail - on most Samsung projection TVs, this would be the DM board. Exhibited symptoms would be screen flickers (white flashes) and in some instances after about a minute the screen gragually turns very very bright (almost white) from the bottom of the screen to the top.

Any of the above would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron as well as access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable venturing into a DIY, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The color is off and the figures are outlined in blue and yellow, plus the picture is cloudy looking.


Press menu on your set scroll down to where it says picture then press select. Now scroll down to convergence and press select. A white cross should appear on your screen. Your objective is to merge or converge all the crosses into the one white cross. If done right you should see only the white cross. You may see a little green and blue but don't be to picky. Make sure you read the on screen instructions on how to do this. After this you continue to the next step and you should see several white crosses across your screen. Do a convergence for each one of these crosses. Your picture should brighten up and your yellow and blue lines should go away. If it doesnt you have a bad convergence chip or some bad capacitors. If the first step doesn't fix it I would that you had a tech come and check it out.

You have one of two problems. Sometimes both.

Problem #1) 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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Problem #2)

Your TV may have a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem



  • 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.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can hire a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a step by step picture instruction guide, original OEM parts, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
