I can't make heads or tails of the color bands...
It's measuring 200 milliohms.
Thanks

My guess is .18 ohms 5% tolerance and maybe flameproof?. Did I win?sigpicThe Sky Is Falling

Re: Help me identify this resistor please
Thank you!
Yes, precisely... Connected to the source pin of a 10N60C...
When the FET was in circuit, there would sometimes be a tiny burst of continuity from the drain to the source... Out of circuit it is only showing a 0.5V drop between source to drain and no continuity between drain to source so I thought I would start testing some components around the FET.
The symptom of this PSU is that while the LCD TV is on, there is aclicking noise coming from around the primary area, which goes on until the TV enters an error mode where it just cycles between solid RGB on the screen.
What's making this so difficult to diagnose is that I can turn the TV on, have this clicking, then turn it off and back on again, there's no clicking at all, and the TV works perfectly (and I can leave it on for days without any problems).
I've already ruled out cold solder joints.
Any ideas?Comment

Re: Help me identify this resistor please
The clicking is from a relay? Perhaps what is running the relay is getting caught in an oscillation? In old stereos you always have one transistor that runs the speaker relay. Sometimes they will go into oscillation from a weak tranny or some other component.
Just guessing here, I've never cracked one of those tv's open.
Or just leave it on forever. Lol.Last edited by rhomanski; 03-22-2016, 03:17 PM.sigpicThe Sky Is FallingComment

Re: Help me identify this resistor please
I don't see any relays...
I think I found the problem...
It's a 13N50C that mirrors the intermittent behavior...
Sometimes it shows the proper voltage drop from drain to source, and other times it conducts from source to drain... This is looking good... Now I need to find a replacement.
And it is in precisely the area where the clicking noise emanates from.Comment

Re: Help me identify this resistor please
So far so good... I put the 12N60C in (actually it was a Fuji Power 2SK3502 which is a direct equivalent. I thought I'd try a different brand this time since I have two identical scrap power supplies that use them interchangeably).Comment

I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
Resistor shows orange range silver gold and green lines.
Thanks in adv... -
Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.
I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors... -
Hi team, can you help identify value of this resistor. From a PS4 Pro. PCB board model: N300A004L. Location of resistor is R802 as pictured....
