Picture of Samsung TV On/Off Issue - Repair
A few years ago many Samsung TV models were produced with underrated capacitors on the power board of the TV. The result of this issue is a TV that will cycle between on and off repeatedly and/or an annoying clicking noise while turning on. Time to get informed about the issue and fix your TV your self!

It seems there is some money available or a possible repair to those with this issue that meet the qualifications listed. If you don't meet the qualifications, you're not interested in the red tape or just like the satisfaction of fixing things your self continue you reading and I will show you how to fix your TV for under 10$!

Some tools you'll need going forward are a screwdriver, a soldering gun and some solder. Time to get this ship sailing! 

Step 2: Open up the TV

Depending on your TV model you will have a different number of screws to open up the TV. They should all be located on the back and should all be pretty easy to spot. If the back won't come off easily you probably still have a screw in so keep looking. Also don't lose these, you'll need them later!

I did this. Make sure you get the right size capacitors. The first set I ordered were too large in diameter to fit onto the board. They're really packed in there right next to each other. I used the same value capacitors, but I got higher quality capacitors manufactured by Nichicon. So far so good.

Packed in there right next to each other, and next to a massive heatsink, it's no wonder they failed. What happened to space for air to flow? :)

That wasn't the reason. The brand capacitor Samsung used wasn't the best.

On/Off issue happened to my TV recently. Found this through a forums search. Contacted Samsung and as of Feb 2014 they no longer honor the repair cost. Was informed to contact local repair center. May do it myself to try and remedy the issue rather than shelling out a repair bill that is half the cost of a new TV nowadays.

I ended up replacing 3 of these and now it won't do anything BUT click. Any advice? Trash the tv or try again?

hi I have replaced the capacitors , all good for 2 days now I cant get it to come on I used high quality capacitors and now I cant turn it on , what do you think it could be regards Geoff

how much larger of a voltage? I'm having trouble finding the right one. I found plenty at like 250v 47uf but the one I took out is 160v 47uf...

the voltage rating on the capacitor is the maximum voltage it can handle, in other words you can go higher without a problem, but dont go lower.

Where do you live? can you come over and do that to my tv?

Excellent instructions. Bought the capacitors at Radio Shack, so far so good!! Works like a new one.
