Blow capacitor 820uF 25v? to replace 1000uF 25V other capacitor?

It is probably OK, possibly a filtering capacitor, besides no one makes a 820uF any more.

Hi I need to replace 3 x blown capacitors for my LCD monitor. They are 820uf 25v. Do they have to be an exact match ie ceremic/tolorences?

They can be 1000uf 25v (20% higher value is OK), higher voltage is also OK but it may not fit the board. The temperature rating must be 105c and Low ESR type which is very important for switching power supply. You should replace them in a set.
You can get the PANASONIC FM or FC series from DIGIKEY, or from Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Blow capacitor 820uF 25v? where can i buy them? or how to replace them with other capacitor?

You can buy that to an electronics store near your area. Replace that with same value or if you have higher than 25 volts use it provided that it is same as 820 microfarad.

I have three blown capacitors. they say 820uf 25v. they all solder to the same part on the board. is it necessary to have three of the caps at 820uf 25v. or can they be added up like 820+820+820=2460uf 25v

Hello,

You need to have the 3 capacitors. There is not a 2460uf capacitor, If one of the 3 fail then the other two will still work, if you have just one capacitor and it fails then you have a dead power supply with the first failure.

I have a samsung syncmaster 740 N screen, and it's dead (the power light is on, and the screen remains black, no "no signal" indication or anything). my warranty has expired. is there anything i can do ?...

Open it up and check the caps in the power supply. Check to see if the tops of the cans are bulging. Look to see if there leakage coming from any cap. If the caps are 25v I usually replace them with 35v and use the same ufd's as the old cap. This is usually the fix for this problem, Hope this is helpful.

Sounds like it could be a weak capacitor. Caps that are bad or weak will work after they warm up.
