My Samsung 56" HDTV DLPTV switching On and Off intemittently

by srikanthmech / February 9, 2009 3:41 AM PST

HL-5679W 56" Samsung DLP TV is switching on and off intermittently (3 or 4 times).. I called samsung and the samsung service person who checked my tv told me that the Power board has a problem and needs to be completely replaced... the total cost for the power board is $400 and $250 for his labor.. So i am spending about 650 bucks on this tv, which is just one and half years old (the 1 year warranty has expired of course).. I saw similar blogs in this forum that said that this was only a problem with a few capacitors that would cost less.. Isn't there a way I can spend less by just fixing specific capacitors in the powerboard instead of replacing the whole damn thing ? .. I stay in NJ, please let me know if there is a cheaper way to get out of this power board mess (if there is any service provided who knows the stuff and can fix it for less) .. These samsung people, i am sure dont know much about this, because the guy who came to check the tv, didn't even open the tv, he just said replace the powerboard by looking at the intermittent on-off...

Also the samsung technician had told us that it will be a power board problem and definitely not a LED problem..

Thanks for the feedback. Are you already working with a technician?

If that's what the tech said, he would have an advantage of knowing more than I would at this point.

On/Off switching

My 16 month old 52 LCD had the same problem. The switching kept getting longer and longer (about two weeks). Finally, it wouldn't turn on at all. Samsung rep came out, went immediately to the power board, looked at the 2 capacitors that go out, verified that they were out, and replaced the power board. Board was $150 + $100 to come out (repair shop was less than five miles away), and $100 to change out the board. He was in and out in 10 minutes. Set works great now. It seems to run a little hotter than before. I kept the old power board. Known problem? Happy
