Question about Samsung HCL4715W 47" Rear Projection Television
I have asked 4 techs with 15+ yrs experience and got 3 different answers :( My color is turning a little yellowish/green and have seen a yellow or organish circle about 5" in dia on the screen but only when it's on for awhile. I puilled off the front to look into the 3 tubes... Red has a image, Green has a image and Blue has no image but is as bright as the other tubes so I'm guessing this is probably my problem. 2 tech say it might be the Board, 1 says it has to be coolant and the other tech said the tube is going bad and they don't make the tubes anymore, then goes on to say SAMSUNG tubes can't be recooled... Who is right lol Any ideas ? I'd haul it in for service but no truck and they want $100 just to come look at it.
If you did not see the picture on the blue tube; that is your problem -- the drive signal is not getting to the video amp and the mixed color from the green tube and the red tube is giving you a different color wich is unnormal. a good picture is when the 3 crt are emitting the video
