Question about Samsung PCL5415RB 54" Rear Projection Television
SOURCE: PCN5425R Fading in and out
No It is not the picture tube.
First, I would suspect a bad solder connection (cold solder connection) to find this problem hit the side cassing to see if the picuture goes away or comes back.
Another way is take the back cover off and tap gently on the boards with something not conductive or your hair would look like mine. The most commond section is power supply and neer the Horizontal flyback transformor.
The horizontal transformor look at it, it's a big greyish darty little thing about 3" x 4" and stand up about 4" with a big red wire going out of it. Don't touch it, it has very high voltages, just look what it done to my hair I'm telling you don't touch it along with it's red lead's. Just look to see if it is arking if so replace it.
When you have convegence problem , it is mis aligment of the colours in the genmentry aligments.
I would suspect more in the power supply section.
What about Bob

well..it's simple really...yellow is from a degrading video unit and system board..so, you'll find that it's high time for a major service situation.

The high-pitched whine is definitely the color wheel. The early color wheels had problems and many had to be replaced. As part of the turn-on process, the TV checks for light and then checks for color wheel sync. If the bearings are wearing out/dried out, it could cause issues with getting the proper color wheel sync, causing the set to not pass the turn on sequence.
Check Sears or partstore.com for a color wheel. I like sears for experimental replacements since they allow easy returns.
BTW, mine is an early 61". My color wheel was replaced when I had to replace my Light Engine. My in-laws 50" was an early one and theirs went out within 2 years.

Sounds like your color wheel may be at fault. Do you ever hear any unusual noises coming from the rear of the TV? Color Wheels usually make a humming sound as they go bad. This is because the tiny bearings in the color wheel motor have begun to misshape from use and heat. This is a known issue in this TV! Expect to spend $300-500 to have this serviced by a service company. If you have the right stuff, you can do it yourself. If you search the web, you'll find a color wheel for this TV for under $100, but installation can be tricky.
