Our TV was professionally repaired a few years ago, because it would shut off on its own after a few hours. I can't exactly remember what was fixed/replaced, I think it was the power supply. But a few months ago it started having problems again.
When the TV is turned on, it displays a distorted blue screen with faint white lines running through it. After completely powering up, it would shut itself off immediately, making a slight fizzling sound. Sometimes (about 40% of the time) it switches on normally, and everything looks OK. But after a few minutes the blue screen comes back again for a split second and shuts off.
I'd like to give this TV away, but first I'd like to have some idea of what could be wrong with it, so as to advise what needs to be replaced/how much it may cost. Any suggestions would be greatly appreciated. Thanks!

Re: TV Shuts off, Screen Problems
The problem could be the power supply, the flyback trasformer or simply a bad connection. A repair cost for this TV set could run any where from 75 bucks all the way up to 225 or so, depending on the problem. Good Luck

You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.
BUT DON'T DELAY AS SOONER LATER TV WILL NOT RESTART..
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
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!
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.
