If its programmed it will always try at the exact same time, other than that cover on the front of the set the remote receiver---a lens to see if some light is triggering it on, Had one customer where a odd colored streetlight which came on on off was turning his set on.

SOURCE: samsung lcd tv power problem

Check the solution by billn352: $7 Fix! It Rocks!
billn352 even has the cost of the replacement capacitors correct! Thanks guy!

When my Samsung quit six months ago, the three solutions posted on FixYa were (1) Pay $300+ parts and $200+ labor to have it fixed, (2) Do #1 then rag Samsung until they repay you for the defective circuit board and (3) Get another TV and avoid getting stuck eith yet another defective circuit board. I chose to buy a 47" Phillips at Wal-Mart. I don't feel like paying big bucks every 18 months to keep the Samsung alive. I put the Samsung in the closet and took my lumps.

This month I revisited the solutions on FixYa and found the post by billn352! A $7 FIX and it Works!.

I pulled the Samsung out of the closet, laid it on a padded table, removed the plastic back (lotsa screws!), located the capacitors and removed the circuit board (more screws). The four capacitors are easy to locate. At least three of mine had black **** oozing out of the top of the cans. I ran down to the strip shopping center and got the four replacements at Radio Shack--under $7 with tax.

The capacitors are polarized (they have a positive and a negative lead) and I have a buddy who loves to solder and drink beer. So I asked him to do the hot stuff, assisted by a copy of the billn352 post to further identify the capacitors by component number and a six-pack of Miller Lite. Yes, the replacement capacitors are larger than the originals and Yes they fit nicely! So easy that a "drunk redneck" can do it!

I also checked the current prices for this model Samsung on the Internet. On one list, a new unit was offered for less than $400. Most I found were in the $500-$900 range. Give it another year and what do you think these sets will be worth! A $7 fix is worth doing: Maybe a $400 fix is not.

SOURCE: Acoustic Solutions TV Fault

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.

SOURCE: Samsung LN32A330 turns itself off after 5-10 minutes of being on.

its usually the 2200 microfarad cap on the power board that stops working. its really easy to replace and its only a 5 dollar repair part. use a 2200 mF cap rated around 25 volts instead of the usual 10 volts. samsung is famous for bad caps. if the cap feels buldged than this is the problem

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

Self- reboots at start-up, then shows picture but with pink dots.

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM811, CM812, CM817 & CS806; 1000ufd 25volts. It is the board to the left and you notice that the four cap tops are swollen.
It is easy to replace get a stanard solder pencil and you are in business.

Thanks for using FIXA, BIG IRISH.

T.V. turning on

yes my 26" sharp aquous LCD does the same thing, turns itself off and on at random times without explanation. I sent to authorized service center they replaced the power supply under warranty then it failed within 6 months and neither the repair center nor sharp will do anything about it other than sell me a new powersupply for $425.00. I have contacted a power supply repair center in Texas who has vowed to fix it once and for all. We'll see in the next week if they fix it or not.
