Hello friends, I have found a 5-band resistor at the source of a led tv .. that has the gold in the center and no resistance calculator accepts it. the colors are as you look ... brown, green, gold, brown, black .... or .... black, brown, gold, green, brown I have measured it and it gives me 2.3 Oms ... Thanks for the help folks.

There is no black as the first band. The order is the first you put.

Thanks for the Ennio Data, I have found a color calculator that I accept the gold in the center .. but it is as if I ignore it, I get 151 omh .. or 1500 omh .... I don't know, I am confused and the resistance is fine all the colors look perfectly .... I want to change it but I don't know if I put one of 151 .. for fear of damaging the plate more.

It can't be 151 ohm because gold is before brown.

If the R looks good and is giving you measurement so you want to change it?

I have not said that I want to change it if it is not necessary, but if I find a component that I do not know or do not understand its nomenclature, I am automatically interested in knowing it, knowing how it is checked, and what function it has ... since I like the electronic, and all new knowledge, is good. I am also curious by nature and I like to learn ...

Well in your comment to answer Ennio you said: I want to change it but I don't know if I put one of 151 ... for fear of damaging the plate more ... That's where my question comes from ...

ok, I wanted to change it because I was not measuring it well because it gave me a bad reading, when I already explained how to do the reading more accurately .. I realized that it was fine .. sometimes there are components that look good, but they are devalued or in short ... you know ... the best thing is that I have managed to get the tv to work, even if it cancels the ignition circuit ... by plugging it on it turns on and with a switch on the cable it turns on and off, it's a tv very large 58 "smart .. very expensive, and the source is not found, for now this solution is acceptable to me.

Measure what the multimeter marks by joining the tips. If it measures 0.5 ohm approx. plus the value of the R, it can give you the 2.3 ohm you measure. So it could be 1.5 ohm.

Thank you very much, Ennio, I have done what you told me and you were right ... by putting the tips in the tester in 200 om ... it gives me 0.6 ... then if it is 1.5 ... and therefore it must be correct, and It shouldn't be the problem I have at the source ....
I have an open question that nobody has answered me "Samsung TV fails in the power supply", I have elaborated the best possible question and I have edited photos for brands the components and problems that I have detected, I would be very grateful if you would take a look to that question .. regards.
