SINCE YOU HAVE REPLACED THE CIRCUIT BOARD,THE NEXT STEP WOULD BE CHECKING VOLTAGES GOING TO THE CONV. BOARD COMING FROM THE POWER SUPPLY CIR. BOARD.....IF NO VOLTAGE METER,,SOMETIMES, THERE ARE FUSES ON THE POWER SUPPLY CIRCUIT BOARD THAT SUPPLY THE NEEDED VOLTAGES FOR THE NEW BOARD YOU JUST REPALCED...UNPLUG THE SET,,CHECK FOR A BLOWN FUSE----I THINK THERE IS 2 OF THEM--ONE FOR A NEGATIVE VOLTAGE AND ONE FOR A POSTIVE VOLTAGE FOR THE CONVERGENCE BOARD..GOOD LUCK--SORRY, MIGHT NEED A TECH...TUNICA

Could be a bad blue TUBE. Samsung tubes were NOT too good.

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.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
