Need some guru help

joshuastovall

Sorry if this ended up in the wrong area but i need some help from some knowledgeable people. I am trying to repair my tv. I have identified three capcitors that are the problem they are blown but im not sure what to shop for. Can someone point me in the right direction of what to buy?  Pics posted the side by side ones look to be the same marks the one by itself i think its a different one.

 

My soldering skills are good but never got the chance to take classes to learn more. So im comfortable doing the repairs just not sure what to buy or where to buy them.

 

Thanks any help is appriciated.

    How did you determine the capacitor needs replacement? You may be right, but sometimes it's good to keep in mind that there may be other things that can be wrong. Another is that the safety of tinkering with such equipment - capacitors can hold a charge that can be unpleasant through to even lethal.

     

    From your image, which is very blurry, it looks like a Samyoung 820uF 250V electrolytic capacitor rated at 105 degrees C (in brown). Ultimately, if this is the part you want to replace, then it's good to purchase a low-ESR capacitor of an equivalent 820uF rating and a voltage rating of at least 250V. Changing with another unit that comes from a reputable brand is highly recommended (e.g. Panasonic, Rubycon, ELNA, Nippon-Chemi-Con, Nichicon or Sanyo). You will need to check the spacing between the legs and the height of the can if it's a tight fit.

     

    Likewise, perhaps try taking a clearer photo - use the Macro mode on your camera if you can. When dealing with mains, be careful - any mistake could be disastrous. Electrolytic capacitors are polarized - get them in the wrong way around and you will ... have some loud noises and magic smoke.
