Calling electronics guys, need assistance.

Naw, this is a decent looking polished stainless steel desk lamp.
I still have that torchiere lamp, now that you mention it. Should dig it out of storage and see if that has issues.

Hmmm...Lets give this a go. It's been a while.
The Brown component, Looks like a capacitor to me <mylar capacitor perhaps>
The Black component is probably some sort of transistor or rectifier.
The blue one...My gut instinct tells me resistor<probably custom given no color bars>, but it could be a diode of some sort, or even another capacitor<less likely imho>
Since nothing looks swollen or burnt...I'd place the blame on the transistor. If there are any readable part numbers on any of the compnents post them here, maybe I can cross reference some of the numbers and come up with something more concrete.
Xar256 ;D

Maybe I can help -- maybe not. :P
The square black thing could be a voltage regulator. Does it have any numbers/letters on it? You can then figure out what it is. A voltage regulator simply puts out a constant voltage -- 12 V, 5 V etc. Easy to replace.
You can measure the pot while it is connected to check if it's toast. Connect a multimeter to the various pins and turn it, if the resistance doesn't change it's busted.
The big orange thing is a capacitor, read the numbers, a replacement should be cheap.
The blue thing might be a diode, or maybe a resistor. Some resistors are coated though. Measure the resistance.
My guess is the pot is toast, you can break those fairly easily by twisting them too hard. It's a really simple circuit, someone with a real knowledge of electronics probably knows what it actually does. ;D
edit: after reading the reply above, the black thing is mostly likely a transistor. I don't think they'd put a voltage regulator there. lol

It's a dimmer circuit. Looks like a pot, capacitor, DIAC diode, and a triac make up the simple circuit. Chances are the triac is shot.
This is easy to fix.

Bingo! It is a dimmer circuit.
The triac is the transistor looking thing?
There are letters and whatnot on it, but I'll need a magnifying glass to read it. It's really small.
