Read Chapter 3 about adjusting the convergence controls. These are to do with the alignment of the colours. It will help you fix the 3D look.

A constantly blinking light means shutdown.

The most common issue in this model is convergence-----if the convergence circuit has railed (this means shorted parts) it can cause the set to do what you describe.

Before I suggest a course of action----what is your skill level with electronic repairs? Can you solder and or do a visual inspection?

Hi , first thing is check for leaks coolant in all 3 tubes. It is a very common problem in Samsung projection TV. This means, if you have a leak, it makes no sense to repair your TV, isa big money for parts. Another possible solution would be convergence board is damaged, two STK 392-040 IC's number; also has associated resistors that can be opened or burned. Be careful, Try to open the TV and watch these two important details. If you have further questions, do not hesitate , I will be here.

The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.
