Just got this defective resistor out of my tv set and it's very weird. Look at those colors, it got gold on the 2nd stripe and possibly gray(?) on the 4th stripe. How is that possible, can someone tell me what is the value of this thing?
Supposing the 2nd stripe is brown (that doesn't look any brown in close up view, much more like gold), that still doesn't explain the 4th stripe which is gray or white (the 4th stripe can't be higher than 4) and the article you have linked says that only 6-band resistors have temperature coefficient.
And it's connected to dozens of things, I ain't got the expertise to deduce that
What if you're looking at it backwards, and that last stripe is actually white? That would make it white-gray-red-gold-green, which is 98.2 ohms 5% tolerance.
It definitely looks silver to me, but perhaps it's a shiny white....
It's definitely a fusible resistor, of a low ohmic value used in series with the main PSU rail.
It appears to me to be grey red (ie 82) and gold third bad would indicate /10 so that would be a fairly typical value of 8.2 ohms. The silver will be tolerance and the green is unusual for sure but since the main property of this resistor (after resistance) is fusability so the green might indicate something to do with that, ie wattage. It looks about the right size compared to the 2W fusibles I stock so I guess it's a 2W fusible.
A green band might indicate a 5W fusible but I just don't see it being big enough to meet that.
Did anybody ask "what resistance value does it measure"?
This resistor appears to be part of the PFC (power factor controller) circuit. You could do a google search for the datasheet of the ic associated with this resistor which may have an application circuit or search for the service manual of the tv which may have the psu schematic.
Could either be a fuse or a NTC inrush current limiter. On the board it is labled R6 so my guess is a NTC thermistor. What does it measure? Looks like there is a place for a jumper next to it?
No matter which it is I doubt it is your problem. Take a couple of voltage measurements on both ac and dc on both sides of the diodes right above it. then measure on both sides of it.
I don't think that I have ever seen a resistor fail short.
I think the best way to proceed is to try to find a schematic, or reverse engineer one if necessary. From that we may be able to figure out what it's purpose in the circuit is.
@ronv The TV is working but no sound in the speakers and line out. The fuse is fine.
@ChrisP58 I looked at the schematics but didn't find this resistor there. I don't think it is there. All I know there was a zener diode 6v8 in short (the one almost in the middle, between the blue resistors in the 2nd picture, which is connected to this resistor) and the resistor with the weird stripes.
