    Replacing Capacitors on samsung tv with larger ones

    hey guys, I was today given a tv for free, there was a catch though it turns on for a few minutes then turns off by its self and gets in a vicious loop of turning on and off, the tv is 32inch samsung LA32R71W, its about 4 years old, i started off by going into the factory setting to check its operating time and its only 700 hours but still done a factory reset, opened the back to check everything and i think a few of the capacitors are buggered, there not hugely bulging but the have small raised dimples in them so im just gonna go ahead and replace them, the only issue is i got to uni (college) so parts,spares and money is at a minimum, living in australia the closest place to me is jaycar, the capictor that needs replacing is a 1500uF 35V 105degrees, the closest i can get locally is a 2200uF 50V 105 degree capicator, the other one which is 1000uF 16V i can get for a direct replacement but the other i will need to source overseas and cost will just add up making it not to worth it if its not just the capicators ie needing an entire new powerboard also, so replacing the obvious first will the higher farads capacitor work??? if there is a possibility of it may damage it im not to worried it was free, if i can fix it cheap its going to go to a friend who dosnt have a tv.

    Can you get capacitors from Farnell or CPC in Australia?
    It's less of a capacitance issue and more that most capacitors from Jaycar are general purpose / general duty so not suitable for PSUs.

        Re: Replacing Capacitors on samsung tv with larger ones

        Rs trade is a good hour drive from me but i see that they have a online ordering, so i will just order from them, i guess i didnt search enough thankyou, any certain ones i should be purchasing???

        While im at it, are there any other test i can perform to see if it definitely is the capacitors??? im trying to get hold of a multimeter that can measure capacitance to test each one to make sure they are buggered, its a 2 second job unsoldering and resoldering them but from what ive read this is the main issue cheap capacitors on the samsung tvs

          Can you post a picture of them? They can usually be spotted.
          IIRC the R71 is a 2007 model which is plagued with cap issues so it certainly would not surprise me...

              Samsung UN70tu7000wxza no standby light, do I have bad capacitors?
              by ctroxtell
              I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
