How often do you have to replace the lamp on a 56DR650? Replaced in April of last year and is now exhibiting same problems.


Average life on a OEM lamp unit is 2,000 hours which usually works out to 2 years (unless you use it a awful lot of hours).Bad color wheels in these sets usually exhibit a high pitched sound or fan like noise--even heard a few that sound like a garbage disposal.The wheel faces the lamp so if you can remove the lamp and look at it to see if shattered or missing pieces.Someone posted instructions for the replacement online--let me know as it is on my bookmark list now.Only way to know (other than taking lamp out and finding it shattered inside) is to replace it.May be the lamp again, maybe the Ballast that drives it etc, kind of like starter on car turns but car will not start.Try to look at turn on to see if lamp even fires for a moment--then inspect color wheel etc. If you want the URL for the installation of the wheel let me know.SD TECH

Samsung p6163wx - lamp sign flashing with a loud noise fan on, no picture. Replaced with a new bulb - did not solve the problem


This set may use a color wheel if it has a lamp. A bad color wheel will make a fan like or high pitched sound.

If the wheel actually shatters (it can) the set will not function and will turn the lamp off.

See photo of color wheel and if you need to know I can tell you how to look at it.

Ballast or color wheel next?


The color wheel will normally spin-up even for a brief moment when the set is powered up. I have not seen a color wheel go out with a lamp. I have seen a ballast go bad with a lamp. I would replace the ballast first. You did not state wheather the color wheel was noisy or not. On the Samsung DLP, the color wheel is normally very noisy before it is gone. I hope this will help you.

YELLOW AND BLUE SQUIGGLY LINES ON THE RIGHT SIDE OF THE SCREEN


Hi Fkanode.
The failure(s) in your TV is related to a part called light engine or optical block and Sony TVs are known for these kind of failures with the video showing with different colors or lines.
Check the link provide for more info or if you would like to try fixing the TV yourself.
Let me know if you would need further assistance.

Color went to grayish green, dull picture.


It ended up being one of the connectors on the composite cable. I did not know that the different colors came through separate cables. I do now, Thanks.

Will my lamp still turn on if my color wheel needs replacing? How will I know if it is my color wheel or ballast that needs replacing??


If the color wheel doesn't start rotating or get up to the proper roatation speed then the lamp will never fire.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
