This is a possible fault in the power supply, and can be a problem with some decoupler caps on some of the boards. The vertical bars and unstability are usually attributed to having high frequency noise and or clocking pulses crosstalking on to the power distribution lines that run through the boards. This can be switching power supply noise, or cross-talk from clocking pulses.

Another thing that can cause your described fault is unstable clocking between the devices that are reading and writing to the data busses. There are a number of data busses running through the set for the boards to be able to communicate with each other.

The tech will use the process of board swapping to service the set, and then do the adjustments as necessary to make sure the new boards match up.

Yes... DLP sets are fairly expensive to service!

This is my personal opinion. If the set is out of warranty, I would change for a Plasma or LCD set. If you compare the performance of these to ther DLP, the difference is very big. From what I am seeing from a service point of view, the DLP's are lower in reliability.

Hello Fonzell!
Regarding the tv turning, my question is, do you hear a clicking sound? if so, it's most probable tio be your ballast, that might not have enough voltage to keep on with your lamp, and that's why it shuts off.
You could try replacing it and seeing if it resolves your issue, I believe they're running around 70 dlls..
have a great one ! :)

SOURCE: Samsung 61' DLP Color problem.

If you are using Component inputs, check to make sure that the Blue Video Cable has not backed out of its connecting jack at either end or the cable it's self being bad. If you are using HDMI I would suspect that the Digital Board being bad. It would be odd for the Color Wheel to cause the problem but cannot eliminate it as a cause. The Lamp would cause the picture to be darker but not cause a color to drop out.
I would call a professional to trouble shoot it unless you have the knowledge and the tools to do so.
Hope this helps,

This TV is horrible. I have the same one and not even a year replaced the light bulb twice. Very disappointing for a Samsung.
