This is a 334k precision resistor. The right colors are (orange, orange, yellow, orange and green(0.5% tolerance). Good look!

Good day sir. I also have an 732n samsung that only shows the picture for one second. Can jou please send me an email so that I can reply with pics of the mother board. Then you can show me where to measure the transformer please.

Sorry we don't carry any schematic. Try eserviceinfo.com

Hi Alex,

If you see the surrounding circuit you will know that the resistor already gone through some heat. The color band is not vibrant anymore. Sometimes you may think that it did not change color but actually it already changed.

I have the service manual for that monitor, and guess what.. the inverter schematic is literally the same as the one in the backlight controller I.C datasheet including values and component labels (you can look it up, its FAN7310 or FAN7311 from Fairchild). As for the burnt resistor, the coloring did not change since the coating did not degrade from the heat. Here's the picture http://i.pictr.com/hns727uhcz.jpg You can clearly see that the color bands are still intact despite the heat which caused discoloration of the surrounding area (becomes black'ish)...

Hi Alex,

Sorry I do not have the schematic. As for the resistor the 220 k could be the original value because after a resistor went through heat the color may change. Yellow color could be orange and red color could be turn into brownish.
