Question about Samsung DLP HL-P5663W 56" TV

Samsung HLN507W 50" DLP Television

My son was watching TV and said he heard a pop / explosion. Now the the TV on plays in black and white and after it is on for a little while the picture starts to get smaller and flicker. From what the little I have read it appears I need DMD board. Does anyone have experience with this problem? The boards are very expensive is there anyway to repair the board or find it a cheaper price?

Parts are from the manufacture only unless you can find a used board from a scrap set. A used board may have a lower reliability than a new one, and there will be no warranty. After changing the board, there will probably be some calibration required to match the new board.

Almost all the repairs on modern TV's are done with board swapping. This is because of the complexity of the design of the circuitry, and the way that they are assembled. These boards are using multi layer assembly, with embeded component technology with very high density surface mount technology. To troubleshoot these boards and then change parts would require very extensive instrumentation and tools that would not be feasible for any service centre.

I suggest you give the set only to an authorised service rep to have it serviced properly.

As for the DLP sets, from the statistics that I have been seeing, they are general lower in reliablity than the Plasma or LCD sets.

The DLP sets also do not produce as nice a picture because they are using projection technology rather than direct view technology. If you go in to any of the TV stores and compare them to the Plasma or LCD sets you can see the difference right away.

Lost color, loud buzzing sound HLP4663W

This can be the colour wheel assembly, or the servo drive board, or a fault on the circuit board that does the sync processing for the colour wheel.

You will have to have the set properly serviced.

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.
