So either one fo the fuses is bad or the power board itself is bad, but my Samsung FP-T5084 is dead. After doing alot of readin on different forums it seems its a common problem with this model. I've had it for 3 years and am now out of warranty. This is the 2nd time this has happened since i've had the tv (luckily, the first time it happend a year and half ago i was still under warranty). Because of this fact i'm planning on fixing it myself to save some money. I need a tool to test the fuses first.

Nope, absolutely no signs whatsoever. Was watching tv w/ my son on Sunday afternoon and all of a sudden it shut off and wouldn't come back on. Tried multiple variations w/ the plug ins and the power strip and finally deduced that it was either a bad fuse or the power supply itself once again.

Capacitors can go bad even without showing outward signs, and the usual test done with a multimeter, where it's set to ohms to verify that the resistance gradually rises as the meter charges the cap, is only good for finding really, really bad caps, such as those that have shorted. Even a capacitance meter (many higher priced mulitimeters have that function) isn't very useful, and it really takes an ESR meter to verify that caps are OK.

Maybe the problem isn't capacitors but solder connections or shorted diodes or transistors. Generally, solder is most likely to crack around the most physically stressed parts, like connectors, heavy components, and hot components, which include transformers and high power transistors, diodes, and chips. The latter three are often connected to electrolytic capacitors and can be killed if those capacitors go bad. Also one expert recommended always soldering the leads of any transformers. A multimeter can test transistors, diodes, and sometimes even power chips (their output transistors. Also some of those chips are just pairs of transistors). All testing can be done with the AC power disconnected.

It's possible a capacitor located somewhere other than the power supply has failed, and many circuit boards have their own voltage regulators, which are typically much smaller and use tiny coils.

BTW, Samsung's own capacitors aren't considered very good, and it's better to use a Japanese brand, like Sanyo/Sun, Panasonic, or Nichicon. The electrical characteristics should be the same, not only in voltage and capacitance ratings but also ESR and ripple current.
