Question about Samsung PCL541R 54" Rear Projection Television

1 Answer

Color going My PCL541R seems to have lost all colors but orangish and tan. As a relative of a friend said once the green and blue ran out of the tv, It seems to improve slightly when it is left on all day but not much.

Re: color going

Your colour guns (that's what they call the light tubes that produce the 3 main colours, red/green/blue) need to be fixed. One or two of your guns need to have the liquid that protects the lens flushed out. I had the same thing and the repair man came in took the unit apart and removed one of my light guns (blue one) and showed me the dis-coloured liquid. He drained the liquid and added new clear liquid which protects the heating of the gun and everything was perfect again.

I think I lost a gun? Picture seems to be losing a color. lines are off and can't seem to get a good picture.

If you can find a channel or video with pure red, green, and blue you can check the quality of each individual color. If by "Lines are off" you mean the picture has a ghosting or 3-d look than that is the convergence. You can do some adjustment by entering the user menu and scrolling down to the second page and selecting the convergence option. Set the center crosshair then work your way through the positions. If you can't adjust one color in one direction it is probably your convergence IC's and related components.

Phillips Model 60pp920217f

No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs

Toshiba 65hx81 65" Rear Projection tv. black & white color/green

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck
