Samsung LNS4051D. Originally had red blotches replacing dark/Black areas. Now colors have gone totally bonkers with every color, every where randomly even with the color control on the way down. I noticed others having the same problems on the webb. Samsung says the problem has never been reported. HELP!

you didn't provide age of your projector, but it likely is about dead, and not worth fixing again.

Hello,

a picture would be great, what you are describing would be a number of things. Being that it's a Samsung, I would suspect a failing LCD panel, very common with older Samsung's and Sony's. Other possibilities are a bad main board or a damaged LCD screen. I guess I should ask if the problem is always there or does it go away when the set warms up? If I have been of assistance, please sign my guestbook!

no you need to adjust the color wheel to factory specs by getting into the service software. The color wheel has to be timed to the engine.

Listen, for what it is going to cost you to fix the unit, you are better off replacing it and having a new warranty to boot. Simply not cost effective to repair given the cost of a new monitor these days.

If you have had this unit for awhile it could just be the lamp. If the image does'nt brighten up you may have an issue with the light path. The color wheel produces the color. If there was an issue with the color wheel you would most likely have a black and white image.

How is the color of the tv menu. If menu also bad replace light engine. If menu ok replace digital main.

Hi there
Firstly reinstall the graphics drivers, if its still the same there is a problem with the graphics card and you'll have to have it looked at.

Good luck and thanks for using Fixya!

Its probably the inverter. its a device that powers lcd screen's. ebay the model # and include inverter. it will give you a ballpark number to work with
