I note the number of people who have replaced the colour wheel . My wheel failed after 2 years use and the repair man is still waiting for a samsung replacement part over 2 months later.. In addition, he has just had an identical sp46 L6HX dropped in with the identical problem.
It's clearly a mechanical part, but given the number of people who appear to be having problems...is it a potential design problem and worth trying to take it further with samsung? It's not exactly a cheap part !
Those motor bearings in those DC motors do wear out as they are not really bearings but are called races. They are self oiled and are made out of brass. Never heard that about putting the set on a UPS so the motor could shut down properly? A DC motor is on or off. a freespining motor does not cause premature breakdown. I have seen where the brushes are bad in these motors and this is caused by use. No motor last forever. It is called friction and the laws of gravity that cause these motors to go bad, NOT a design flaw.
How does the color wheel fail? I was told that any color wheel TV should be hooked up to a UPS (uninteruptable power supply) so if the power goes off, the TV will still be able to shut down properly, much like a turbo in a car. If you shut the motor down while the turbo is still spinning at 30000 rpm, the bearings that were oil fed are now dry and you reduce the life of the bearing.

The image sensor has failed, the symptoms described are unmistakeable. You'll find that shots taken before the fault occurred display normally, confirming that the LCD anel is fine.
It's purely an age related issue and finally kills many digital cameras over six years old. The sensor has not failed prematurely as your camera was designed for a five year minimum lifespan. The only fix is to get the sensor professionally replaced (if available), but the cost far exceeds both the value of the camera and the cost of buying a brand new basic model which will still have a higher spec in most respects than your current model.
Your only fix is to recycle the camera and replace it.

Your camera is giving you the classic symptoms that indicate the image sensor has failed, the only fix is to replace the sensor and it's not cost effective unless the camera is under warranty.
Note that some models were fitted with sensors which failed prematurely, if this is the case then your camera may be subject a "soft" recall whereby owners who complain are offered a free repair, even if the original warranty has expired. All you do is pay for shipping.
As you haven't stated your exact model of Canon then I cannot advise you whether your sensor has failed prematurely, but it's expected to last for a minimum of five years on most Canon models.
You have described the classic symptoms of a failed CCD imaging unit. It happens eventually to most digital cameras and there is nothing you have done to contribute to the fault.
Replacing the failed unit is the only cure and it's a professional job. Unless you can get the repair done free under warranty then it's usually not cost-effective, but as a number of makes and models have suffered premature failure (i.e. sooner than the five year design lifespan of most digital cameras) there are some which may still qualify for a specially extended warranty in relation to this failure only.
Manufacturing and design has improved and the causes of premature failure are now well understood, but the usual lifespan for all but the cheapest digital cameras remains at around five to six years. It's a factor to consider if you decide to buy a replacement camera: digital cameras offer many advantages over film cameras, but they simply cannot last as long as many film cameras.
Are the menus displaying correctly on top of the blurred lines? If so then your camera has suffered a CCD (image capture chip) failure.
There is nothing you have done to cause it and nothing you could have done to prevent it; it's one of the most common causes of terminal failure on digital cameras when they get older. There's also nothing you can do to repair it; the camera is effectively just scrap as repair costs will far exceed the cost of replacing the camera.
Your camera was fitted with the now infamous Sony 5MP CCD; this was fitted to a huge number of makes and models and due to a production error far too many of them failed prematurely. As a result, the manufacturers affected arranged for a soft recall in which any owners who had the failure and then complained about it were offered free repairs. For almost all affected cameras the scheme ended last September and for a handful it continues until the end of this month. The scheme ended as the affected models were by then past their design life expectancy of around 5 years and so any further failures could not be considered to be premature. Your camera will now be around 6 years old so it's lasted really well.
The processes which caused so many ccd's to fail early are now well understood and the design and manufacturing processes have now improved, but it's still a fact that these sensors can and do fail prematurely, regardless of the original manufacturer. Digital cameras simply don't last anywhere near as long as many 35mm film cameras.
If your menus are not displaying correctly, and if images are being captured correctly on the memory card then all that's happened is that the LCD screen has failed. It is replaceable but the cost will still exceed your camera value; you'll also have the CCD failure issue just waiting to strike without warning: it's not a case of "if?", but merely "when?" On balance I'd strongly advise that you don't invest any more money which could instead go towards the cost of a new model.
Although your only fix is to replace your camera, I hope that you've still found my reply to be informative and useful. Please take a moment to rate my answer in return for the free advice.
The ccd imaging sensor has failed. The only solution is a new sensor, but it costs far more than the camera is now worth and is absolutely not a DIY fitting job.
The Sony 5MP sensor in your model is now infamous for this fault and was fitted to many other makes and models. The problem was so bad that there was a "soft recall" in place whereby owners who complained were offered free repairs. Unfortunately you've now missed the boat as the scheme ended last September for all but a very few models and even those will stop this month. The scheme ended simply because all affected models had passed their minimum design lifespan; your camera dates back to 2004 and had a five year design life expectancy. Any ccd failure after that is therefore no longer regarded as being premature.
Although there was a manufacturing fault with the Sony 5MP sensor causing widespread premature failure, it's the nature of all similar devices even to this day that some will fail early. The faults with your sensor are now well understood and improvements have been made, but it's still a fact that very few digital cameras last more than five or six years before suffering a major fault. Even today, top of the line Nikon SLR's only have a two year manufacturer's warranty and most other manufacturers only offer a single year.
It's worth bearing in mind when deciding how much to spend when you replace your camera; if more camera buyers behaved in this way it would force the manufacturers to seriously address the poor reliability which plague these products. Vehicle manufacturers learnt their lesson a while back and as a result it's now possible to buy a new car for less than the cost of a flagship professional digital camera: it's vastly more complex than any camera but can still come with a seven year comprehensive manufacturer warranty as standard.
I would say that a premature bearing failure would be caused by a defective (cheap?) bearing, or improper installation. The axle nut is what clamps the bearing and sets the bearing preload. If the nut is under-torqued, the best bearings in the world will fail very quickly. The 2002 bearing is a Gen1 style cartridge bearing. It has to be pressed into the knuckle, and then the hub gets pressed into the bearing. It the bearing isn't properly support during the press operation, and is pressed across the balls, the balls or races will get damaged... bearing is done for.
The bulb replacement message is not triggered by bulb condition. It comes on after a given number of hours use. If you did not re-set the hours counter to zero when you replaced the lamp then you will get this message prematurely. Don't replace the lamp until it ceases to work correctly - colour balance wrong it it simply does not light.
