    Resistors guide please

    HI
    Don't know to much about resistors so please someone help
    I have a tv power board with two resistors rated 7w 6.8ohms j rated which I think means its got a 5% tolerance.
    The two resistor are reading 7.4 ohms just under a 10% tolerance.
    Is this ok ??
    sorry to be vague

      Desolder one of the leads and measure the resistance again. If needed, touch the probes first and use the REL button on your meter or substract that resistance of your leads.

      No, even if resistors were +/- 10%, it's not normal to be so far away from 6.8 ohm. I would consider more than 7 ohm a problematic resistor.

          Thanks Mariushm I was my leads forgot to consider leads. novice mistake by me

          Having trouble with this power supply board

              Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
              by TinkerTron
              Hey 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:
              The schematic...

              Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul
              by karatzdi
              Hello,

              I know some might say... just buy another one. Sell it as parts..!

              So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
              Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

              Spent some time downloading the Service...

              Hot Air Blew Away Resistors Near Bios
              by brightest_z
              Hi All - I'm in the midst or reprogramming the bios on my gen1 Surface Laptop Studio and I accidentally blew away 2 resistors nearby the bios. I don't have another board to measure values of the missing resistors and schematics aren't available, bbut the bios is a 6x5mm Winbond WSON8, W25R256JWPQ model. The traces are conductive to Pins 3 and 7 (IO2 & IO3 respectively) so I have reason to believe they are 10k pull up resistors since IO2&3 pins are used for Quad SPI instructions.

              Does anyone with more knowledge, and experience than I, know if this is the case?

              ME Firmware Cleaning Guide
              by SMDFlea
              Here`s a quick ME Firmware cleaning guide.

              The guide is basic,its main goal is to show you how to use intel FIT,its highly recommended that you all follow the guide posted at win-raid

              (The attached FIT version is 11, if your ME Firmware (FW) is not 11.0.*.* follow the win-raid guide. Use the tools version for your ME FW, for example: ME System Tools v9.1 For systems running ME v9.0 - v9.1)


              A video,software (intel FIT) and practice bios are all included. I`ll post a better video and more advanced guide at a later date.


              1. Open the...

              Operating caps well below rated voltage
              by Perry Babin
              I think this has been answered but I couldn't find the thread.

              Someone asked me if it would harm a capacitor (10F [not a typo], 24v) if it was operated on nothing more than 12v.

              So, I ask... Does it change any of the capacitor's characteristics/parameters/? in any way if it is never operated near rated voltage?

              If operated for years at 1/2 rated voltage, does it accept full rated voltage like it would if it had always been operated at the higher voltage?

              Or would it require reforming?
