I am having the same problem with my PRT50V24D shutting off and blinking lights. After going to viore.com and calling the number listed, I got recording to call another number. When got rep on line I was told it is made by Samsung, Called their tech support and was told that sounds like power problem or bulb getting ready to go. Also if outside of warranty will have to call repair man to see what's wrong. I will have a repair man out next week and will post his results here. Most likely it's the same issue. This is the tech support number for Samsung 1-888-697-2247. Good Luck man. Matt

SORRY but only you can decide when enough is enough to waste repairing the dinosaur and move on to a more dependable unit .

Well, I have had the same exact problem and since my hlp6163w is still under warranty, I had a technician come out to repair it. And...the winner is a bad ballast. The Ballast has also affected the bulb. So, the answer is you need to change the Ballast and the lamp to get the problem resolved. A faulty Ballast will always destroy a a lamp. Sorry for the bad news as this will cost you a total of $400.00 to replace. It sounds like there is a defect in the ballasts that were made for this particular set and a recall should be made. Hope this helps!

when is the last time you changed the lamp ?  are the fans clean

shorted green cathode.

The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.
