Howdy all I have a resistor on a front panel tv control that has a 5
band color code of brn-blu-red-gold-grn. This resistor is not burnt but
measures 1.62K ohms. from the color code I would suspect 16.2 ohms. If I
replace the 1.62k with a 16.2 the set will not power on. If I put the
1.62k back in set powers and then shuts down after 5 seconds. There are
many posts that identify the front panel cb as the culprit.(circuit
board is no longer available from RCA). There are 4 or 5 resistors and 6
tact switches, and one cap on this board. this resistor is the only
component in the circuit with the on/off tact switch. My main confusion
is the color code and value of this resistor, am I missing something???

It has 3 significant digits instead of 2 and the final value band is the
number of 0's.

A good example of scaling is: a brown/black/orange is 10k -
brown/black/black/orange is 100k.

Faulty resistors in low power circuits are rare - are there any
electrolytics on that board?

Ian , thanks. The band in question is the 4th gold band the multiplier.
Gold will give me a value of 16.2 ohms, however the resistor measures
1.62K ohms. I would expect the multiplier to be brn to get the 1.62k
that the resistor actually measures??

You will get flamed if you keep on top posting.

I'd say the value is 1.6K, 5%. The final green band may be a
temperature code.
WOw, you are the first the get it correct.

Thanks to Peter Bennett. I concur it is a 4 band resistor with a fifth
temp band. The resister is in a low power circuit and has no sign of
damage or overheating.
