It is a two terminal component, and can be replaced easly. But when you unsolder it out of the board, make sure of the polarity, ie, it is an electrolytic capacitor, and have both positive and negative polarity. This will be maked on its body, normally negative will be marked, and should be noted. When replacing it, the polarity of the new one should coincide with, otherwise it will burst out, and will be dangerous. This is the only thing to be noted when replacing an electrolytic capacitor of any type. OK.

Want to know if I can replace a capacitor of 680uf 50v with a capacitor of 1500uf 35v on a plasma main power supply.

NO. The capacitance must be the same. The voltage can be higher but never lower.
So you will need a capacitor of 680uf 50v. A capacitor with a higher voltage rating will work. They just cost more.
So for the power supply;
> Use ones with the Low Equivalent Series Resistance ESR rating
> Use ones with the same farad rating

> Use ones with the same or higher voltage rating
> Use ones with high temperature rating

Give this information to your parts supplier and they will get the right part.

I am having problems with my Samsung lcd tv. Whe i try to switch it on I have a clicking sound and the red led power light flashes the the tv goes off. Can you give me an answer to resolve this problem

Your problem is typical of Samsung LCD TVs. The capacitors on one of the internal boards are rated at 10V and should be higher. If you open the case, you'll see bulging capacitors. If you can handle a screwdriver and soldering iron, you can actually fix it yourself with a few capacitors from an electrical supply store. Simply read the specs off the bulging capacitors and get a higher voltage-rated replacement. For exmaple, if the capacitors say "1000uf 10V 105C", you would replace them with "1000uf 35V 105C" or similar rating. Or an easier method: Recently, Samsung themselves have been making repairs as it is such a widespread problem. Call Samsung at 1-800-726-7864 and they may just repair it for free, even if its not under warranty.

When i turn my samsung tv on no picture comes up or any sound other than a clicking sound from the back of it somewhere near the top left of the tv,. could this be the capacitors?

The clicking is the power relays coming on.
Do you get a flashing power light on front ?
you will need to have it serviced.

My Samsung flat screen tv won't turn on and it keeps clicking - it keeps trying to turn on but then starts clicking again.

There's a couple transistors on the Power Supply board that are probably bad. On mine, the solder joint was bad on the bottom side of the board that pointed me at those transistors in particular. Part number is FQPF9N50C. Also, you could get a refurb or new power supply board of ebay or send your board in for service (also on ebay).Or there's a "repair kit" you can get that contains 4 transistors and a couple caps I think. If you are an electronics junky and like soldering stuff, that would be the way to go... I just ordered the two transistors off ebay for like $6.

Want to replace caps which board is the DM board?

Once you take the shield assembly off, you will see a board, I believe it is the DM Board board. There are four Capacitors grouped together probably rated at 35v 1000 mfd, 105 degree. They should be replaced with 35v 680mfd,105 degree Capacitors. Now once that is done, there is another board under that one. This is the Format Board. It also has 4 Capacitors that should also be replaced. They are the same value as the first Board and should be replaced with the same 35v 680mfd, 105 degree Capacitors.
Please note the Flex connectors at the bottom of the DM and Format Boards. They may not be available from Mitsubishi any more so be gentle with them and make sure the are installed properly when reinstalling the Boards back into the chassis. There is one other Board you should look at. The Power Supply Board is the board on the back of the chassis and also has a number of Capacitors that fail. Most all of the Capacitors that fail through out this chassis will have bulging tops. So any you see bulging, you should replace whether they are on the DM, Format , or Power Supply.
I hope this helps,

ILO LCT32HA36 will not power on

same thing happened to my ilo. There are four capacitors that are bad on the power board. You can usually tell its bad because at the top it bulges out. Here is what you need to do. Unplug the tv, open up your ilo find the power board ( the power cord plugs into it). Then find the capacitors that are bad (they are the around things usually in blue color) and remove them by soldering the other side. On mine there where three 1000uf 16v and one 470uf 35v. Those are the ones that need replacing. I replaced them with a higher voltage rating 1000uf 35v and 470uf 50v. All you need to do is solder them back on but make sure you solder them back the right way (plus goes to plus on the board or you will be in trouble). I found the capacitors at radio shack for about 1.50 a peice. If you dont know how to solder look it up on youtube. If that does not work there might be couple more bad capacitors that need replaceing just need to find them and you can tell by a small bulging top.
