Samsung HC-P4241W 42 in. Rear Projection CRT aging
I HAVE A SUDDEN AGING PROBLEM OF THE CRT AS IT IS ONLY 2 YEARS AGO I BOUGHT THE PROGECTION TV HC-P4241W.
THE AGING APPEARS TO SHOW DISTORTED IMAGES, MORE DETECTABLE IN THE TEXT,
FOR EXAMPLE THE NATIONAL GEOGRAPHIC LOGO IS SEAMS TO BE LIKE A DOUBLE IMAGE, IT IS NOT SO EVIDENT BUT THE PROBLEM IS THA IS A HIGH DEFINITION TV AND THIS IS NOT SUPPOSED TO BE SEEN.

First off, do you not know Internet etiquette? Caps are considered yelling or shouting! So please! head You have the typical convergence failure of the convergence correction IC's. They BOTH need to be replaced. If you have no solid state printed circuit board experience, play it safe and call in a pro to assist you in this repair. Good Luck

Yellow is the lack of blue. It can happen when you are running your contrast - which is your overall light level - too high.
Try turning down your contrast. On CRT tech, contrast should always be run at half what the factory allows as full, on the user controls. Full up is what calibrators call Torch Mode, and is NOT the way to get performance to be in the linear operating range of CRT tech.
If your sides are more yellow than your middle, your set may need lenstriping. Mild yellow on the sides is not uncommon, and usually not noticed. But heavy yellow on the sides would indicate that the blue image needs work on white field uniformity.
the tv color circuit is off frequency change the color ic take a look on the crystal that gives the 4.8.mhz burst could be that it needs to be replace dont rule out the video IF change the two ICs you mention.good luck.from the look of your tv screen that is my conclusion.good luck.email me at [email protected]
