I needed to replace 2 of my 820mf 25volt capacitors in my Samsung LCD TV. Problem is that I cant find these capacitors anywhere. I did found 820uf instead of 820mf. Are they the same capacitors and would I be able to replace my mf with uf's. If not, where would I be able to get a pair of 820mf 25volt from. Thanks

use the correct caps

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

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.

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.

There should be 3 820uf capacitor that need to be replaced on the power board.

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

Check the electrolytic capacitors with values 820uf/25V and 1000uf/10v. Replace them if found leaky..

your monitor got trouble at:
1) monitor inverter board components fail like capacitor or MOSFET diver, it can repair or change this parts to fix.
2) there is disconnection between the inverter and CCFL lamps
need to check by technician, it could be fixed,
3) check the DCpower supply board capacitors swelling which need to reaplace, and fix it.
all steps need to do and fix it well.
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question

I took it apart and found two 330 mfc 25volt swollen capacitors on the main board. I replaced them with 330 mfc 35volt capacitors and tv works like new.
