The capacitors in the samsung 4661 are inferior, this happens to all the ones in this line.

If you are feeling handy and don't want to replace your circuit board, here's what you can do.
Remove the 30 screws on the back of the tv. and the plastic shell will lift off.
There are two boxes, a large almost square one to the left (thats the power board, with the bulging capacitors) and a slightly smaller one to the right. (thats the cpu and circuit board)
You only care about the power board for now.
MAKE SURE YOU TURN OFF YOUR TV FOR AT LEAST 12 HOURS SO YOU DON'T RISK SHOCKING YOURSELF.

Remove the 6 or 7 screws from the metal casing on the left.
To unplug the connectors, either press your fingers at the sides of the connectors and gently lift them off, or pinch them from the small tab in front, and lift them gently off.
Remove the metal casing.
Unscrew the 5 or 6 screws holding down the power board and lift off the power board and take it to any monitor repair shop and ask them to replace your capacitors on this board, with more powerful ones. (usually 16v instead of the low 10v that come with it)
Just tell them its the samsung LNT-4661F and they will know the problem as most people who own this TV have called them.
Or they can google samsung 4661 capacitor kit, to see what capacitors they want to install.

Hope that helps someone, as I had to do it.
But it saved for $400.

    Great news. I have to give massive props to the store that helped.
    I did my advice to a 'T', took the power board to MonitorKing.com in Richmond, B.C. Canada, they replaced 6 capacitors, all with bigger stronger ones, and brought it home, put it together, and it feels like a BRAND NEW TV. No dots, no lines, no problem clicking on and off, picture is clearer than ever. All for (and this is the best part) $40.00 CDN
    These guys are amazing.
    MonitorKing.com in richmond, use them.

    Called Samsung today 11-4-10 if you have one of five symptoms they will send a tech out to change the capacitors free of charge, if it doesn't work your on your own.

  • ridley69hwb Nov 04, 2010

    Which is great if you are in the U.S. and your T.V. goes on the fritz within the 12 month warranty, otherwise your out of luck.

As of 3/28/11 Samsung is still offering to replace capacitors if your set was manufactured during a certain time period. Just give them your serial number and model number

In most cases it is the capacitors in he power supply section that have gone out.

Common symtoms are
-shuts down
-takes a long time to come on
-relay clicks
-dead set

You can get capacitors online or you can get a complete kit with instructions and support from www.TvRepairKits.com . Its a failry easy DIY fix.

Whey does my samsung dishwasher smell?


We had a Samsung dishwasher for 4 years which I finally replaced with a GE. Always had a problem with a smell. I believe it's because Samsung dw's do not drain properly. I took the filter assembly apart several times (at the bottom of the unit) and cleaned it (was always full of greasy black gunk). This would help temporarily. I will never again buy a Samsung dishwasher (or refrigerator).

How to increase the Message Inbox size in the Samsung S5233 mobile


I already knew about the low quality of samsung products. I bought a samsung just because it was the only phone with 3g, wifi and two SIM cards in Brazil (sepetember 2011). This phone sucks. Nothing works. The samsung KIES is a joke ( a lot of error messages, a waste of time). My wife bought an LG, which is much better. I will not buy anything from samsung again.

Do Not Repair. Cut your loses. Always buy an extended warranty on any new electronic gadget, especially a TV. It will pay for itself.

Samsung T819 T-Mobile how do i unfreeze it?


There we go again with those Samsung phones. All Samsung cell phones FREEZE-UP. This is a manufactor's defect. I would think Samsung would correct this problem by now. I guess they dont care as long folks like us still buying their phones. Well, if you so love Samsung phones and cant do without it, then I would advise you to take the battery out for a few second, but tomorrow when you doing something important on your phone it will FREEZE-UP again. Samsung should sell all their phones to Iraq, so that when the terroist press SEND to activate a bomb, the bloody thing FREEZES-UP and sames ome lives. For me, I would never buy a Samsung phones just because of this reason. THEY dont CARE.

The autofocus motor is stuck. It's a Samsung common problem and can't be fixed by the user. If it's still under warrenty you can send it to the the listed repair facility in NYC, otherwise you might wind up paying aa much as what you bought if for. BTW, they fixed mine while it was still under warrenty and three months later, it's broken again with the same problem. My advice? DON'T BUY ANOTHER SAMSUNG PRODUCT AS LONG AS YOU LIVE!!

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.
