i can't seem to tell what colors are what. normally i don't have a problem using the color bands to figure them on but these 2 have me baffled. they are on a toshiba power board right by the ac input. any and all help is appreciated. i keep coming up with a megaohm resistor of different values when reversed etc. but i don't think they are that high but i might be wrong. they read ol when tested in circuit but if they are high megaohm resistors then that is possible because my meter only goes to 2megaohm aka 2000k ohms. the pics aren't the best but 1 from what i see is red,red,green,gray,black and the other looks kinda like gray,red,green,gray,black they both are identical except for the 1 band.

Re: need help identifying resistors
82.5 Ohms . an 22.5 http://www.digikey.com/us/en/mkt/cal...resistors.htmlLast edited by t.j.; 04-20-2014, 01:46 PM. -
Re: need help identifying resistors
That looks like the high value resistors (M Ohms range) for the Hot and Neutral to the safety ground. Look and see if one end of the resistor is connected to safety ground, and if one of the resistor is connected between HOT and NEUTRAL. They are part of line filter circuit.
Can we see the bottom side of the board?Last edited by budm; 04-20-2014, 02:03 PM.Never stop learning

Re: need help identifying resistors
yeah thats where they are located give me a few minutes and i'll post pics. megaohms sounds right cause i don't get any reading on my dmm on the highest setting. anyway to check to make sure they are ok? or if they went bad would it blow the fuse?Comment

Re: need help identifying resistors
What are you working on? I never have to replace these safety resistor, they rarely go bad.Never stop learning

Re: need help identifying resistors
can not really tell by your first picture, but was wondering if that fourth band was silver, if so it may be a 4 band resistor ignore the fifth band, and that would make it a 2.2M ohm, just a thought
second picture that is, red red green silver.Comment

Re: need help identifying resistors
R801 is connected across L and N, another one is between N and Safety ground. They can be left out off the circuit, the TV will still work without them in place. Seems to me you have other problem some where else.Never stop learning

Re: need help identifying resistors
an older lcd toshiba tv model 37hlv66 i saw other threads with the same problem and some were either a firmware fix but mine doesn't have a sd card reader for the fix nor is it listed as 1 of the model the fix works on or switching regulator problems but not for this exact tv. i will open a thread for it either later today or tomorrow.Comment

Re: need help identifying resistors
ok thanks i just wanted to rule them out. will open a thread for the tv later on. thanks for the help. you are right it probably is silver and a 2.2mohm but that isn't my problem now that i got that cleared up.Comment

by unimatrix93Dear forum, I would like to ask some help identifying the backlight circuits resistors to limit the ampere to the backlight leds.
The power supply is a BN44-00852 and I want to decrease the backlight to increase the lifetime of the LEDs.
The TV is pretty much always on, used for CCTV cameras.
I suspecting R9838 -> R9841 resistors but I'm not sure. Thanks in advance!

by bjh06Hello, I have a A2992 board in which has some damage to the rear and a number of missing components. Does anybody have a good photo of this area, and could help identify the missing resistors.
Thanks... -
by tony359Hi all,
I'm diagnosing an old ATX PSU. Symptoms are:
- PSU turns on regardless of the ON/OFF status for a few seconds
- Voltages don't reach nominal
- PSU then turns off and needs power cycle to power on again
I found two charred resistors, they're across the main capacitors on the primary, I think they are bleeding resistors?
They're both charred, but I don't think it's the issue with the PSU as they read 22kOhm
See pics. Is the black band some custom tolerance then? As 22Kohm should be Red-Red-Orange.

by TinkerTronHey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

by Sudsy55G'day all,
new here and fairly dumb electronics wise but learning slowly. i have a project i'm working on that has some surface mount resistors that i'm not sure how to identify. one has 222 on it but the middle 2 is underlined and measures 2.1k. The other has 184 with the same underline and this measures 70 something k. These are both still in circuit. Everywhere i've searched i have not found anything relating to an underline when searching for codes. Do any of the gurus on here know what the underline means?
Cheers
