1. entire grill below front screen must come off (usually held in place by screws in back on either side.)

2. locate and remove inspection plate dead center behind it.

3. Locate small black plastic block with 6 black controls built in; three (look carefully) left to right are focus--DO NOT TOUCH THOSE.

The other three are Screens and will be marked with tiny letters r g b (red, green, blue) and green is always middle.

Locate the red screen (not FOCUS).

With set on adjust red down just slightly(usually less than 1/8 turn.

Since the set will be on TAKE CARE NOT TO TOUCH ANYTHING INSIDE THE SET WHEN YOU DO THIS.

IF YOU HAVE QUESTIONS ASK BEFORE YOU TRY THIS.

My Samsung HLP4663WX/XAA television was making a loud buzzing noise. I thought it was fan #2. I replaced the fan and began getting a


This is typically your color projection drives going out. Soo the picture will go black and white, and the hum will prosist.
It is cheaper to replace the set than it is to replace the Red, Green, and Blue drives; and then have the set re-aligned.

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

OK, Its always best to replace the lens assembly if its not preforming well. never dump the fluid. just replace the lens. As for the double images and the misalignment of the blue convergence line, this is caused by a faulty convergence chip that is located on the convergence board. you will need to replace this board in order to restore proper convergence performance.
