Samsung model LNT5271f excessive relay cycling before full power

I have a Samsung 52" lcd TV, model number LNT5271f. I understand from googling the problem that its most likely bad capacitors on the power supply board. How difficult is the cap replacement and what solder iron wattage would be the best to use?

Thanks,

Steve

Howdy,
Yes, it is very easy to repair. Solder iron wattage should be at least 300 w.

The PSB is the center Board (towards left) after you remove the back off the TV. Remove the shield that covers the Boards and remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Good Luck, big IRISH.

I've replaced every board on the samsung plasma and still clicks


What do you mean by clicks? Plasma televisions are hot cathode ray, there is thermal expansion that takes place due to heat.

I have a Samsung LNT5271F Television and the screen is black. I have sound but no video. I can't even see the menu or volume button, nothing is showing up on the screen. HELP! :S


If the tv has more than one input, you should try switching to the other one. If it has another output(s), you should try the other output(s).

Where I can get capacitors CM852 & CM853; 2200ufd 25volts from ? I have issue with power cycling (Samsung model LNT5271f )


These should be available from most electronics shops e.g. maplin, or on-line e.g. e-bay. Just search for 2200uF 25V capacitor.

Picture on Samsung lcd LNT5271F is blurred sometimes lines color distortion double images then goes away and will come back. Part of the screen will go completely lines then come back. Starting to happen...


Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.

Excessive time to come on clicking


The clicking sound can be an indication of a power supply going bad. If it is under warranty, get it repaired before the warranty runs out. If not, and you're handy with electronics, you can probably find a replacement power supply module online if you google the model number followed by "parts". Otherwise, it will take a repairman to fix it.

Try reseating the LVDS cable.It runs from the main signal board to the T-con board at the top of the panel.

Samsung model lnt5271f cycles on and off 7 times when turned on


Im writing this as a public service announcement. Im seeing more and more of these posts, and I thought I would let everone know my experience.

Samsung televisions (and a few other brands) built in mid to late 2007 had a bad batch of capacitors from China. Two of these 10 volt capacitors were installed on their power boards.

When these capacitors blow, they dont hold enough juce to turn the TV on. However they tend to blow slowly. People experiencing this problem, will see thier TV taking longer to turn on, Then it will cycle off and on a few times before finnaly turning on. And lastly, when the capacitors completely blow, the TV will not turn on at all.

The capacitors are cheap, about 50 cents each. People were origonally repairing these themselves because their sets are out of warranty. It is chepaer to solder in new capacitors, because a new power board costs around $150.

However as of Feburary 2010, Samsung has recognised this as a global problem to their sets. If you call 1-800-SAMSUNG, they will set up a service technitian to come to your house and solder in shiny new 25v capacitors. They will not charge you for this, even if your TV is out of warranty. Mine was 17 months old (well out of the 12 month standard warranty).

Its a cheap fix for Samsung, and much cheaper than buying a new TV.

I would suggest registering your TV on the samsung website if not allready, waiting a day, and then calling 1-800 samsung.

They should take care of it. They have a Service Level Agreement that you should have an appointment scheduled within 48 hours of your call. In fact. I called Samsung on a Sunday, and the technitian was there by monday morning (he had a free slot), so I was very pleased with my customer experience.

Stinks that it happend, but at least its being fixed.

Samsung LCD tv wont turn on


what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

pls rate me!
