If this is the wrong forum please forgive! I am going to attempt a self repair on the psu board on a samsung tv, however I need to source 4 capacitors to replace the failed ones used in the original tv.
Can anyone advise where it is possible to purchase discretes to allow me to repair the board.

Thanks.

old computer motherboards are another possible source

Unless you've got an ESR (Equivalent Series Resistance) meter to test them, do not use electrolytics that have already been used. Electrolytic capacitors are the single most common point of failure in electronics, and even if the device still works it doesn't guarantee that the electrolytics are good or not close to failing.

Buy new ones online from any reliable electronic component vendor such as those listed above. Make sure to match both the voltage and the capacitance values match (for the voltage, make sure that it matches or exceeds the number on the original; for the capacitance, match it as exactly as you can, and keep an eye on tolerance values (the % value beside the capacitance figure)), go for high-temperature ones if you can to increase potential lifespan, make absolutely sure you've got the polarity right (electrolytics can explode/turn into a missile if they get fed more than about 1.5v in reverse bias...).

Hope that helps,

Well carried out the replacement of the 2 1000mic capacitors and it went well, TV worked again as soon as the power went on.. so thats saved me quite a deal of cash..
Happy days
