    Dell 2007WFP resistors under white silicon blog

    My beloved 2007WFP just died on me. It has a green blinking light that just cycles through various display numbers. For a while I noticed it would blink slightly like the refresh rate was off. Nothing I have done has been successful in turning it on. So I took it apart and looked at the USB board since many people have had problems with the resistors under the silicon blob. I looked at the various other boards for the obvious signs such as blown caps, bad fuses, burn marks etc. Nothing looked obvious. I also checked most of the caps with an ESR meter and they checked out good.

    From my understanding 01c resistors should be 10K ohms, 153 should be 15K ohms, 473 should be 47K ohms, 753 should be 75K ohms, 272 should be 2.7K ohms


    What I found was that some reading under the silicon were good and some were off. The 272 resistor that most people were having problems with was good. I don't know what the caps should read.

    Below are the readings I found from top to bottom.

    capacitor 3.6M ohms
    01c 6.53M ohms==>bad
    01c 5.2K ohms==>bad
    capacitor 7.34M ohms
    153 15K ohms OK
    473 30K ohms==>bad
    capacitor 30K ohms
    753 30K ohms==>bad
    272 2.7K ohms OK

    Could most of these resistors be bad? Also what size are these resistors?
    Please let me know what you guys think.

    I have attached pic for reference.

      Re: Dell 2007WFP resistors under white silicon blob

      Just an FYI for anyone having issues with this monitor not turning on. I changed the 2nd from the top resistor and my monitor is working again. The resistor is a 10K resistor with markings 01C what was reading in the mega ohms (6.53M ohms). I know others have had problems with 15K and 2.7K ohms resistors but my problems was with the 10K resistor. Hope this helps someone.

          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...

          Epson EB-U42 projector / Caps with 0.7 ohms ?!
          by narf
          hi all,

          first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask

          i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).

          what i've found so far:
          - the PSU does its job and supplies 12V to the mainboard via the connector.
          - shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
          - not far away, there's the first cap with a resistance of 0.7 ohms....

          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?

          MSI R9 390 Gaming 8GB - short on +MVDD
          by hummel
          Hello,

          Please note I am a noob and all the actions described below are based on the experience gathered on the internet, mainly YT

          MSI R9 390 Gaming 8GB - motherboard model MS-V308 v2.3.

          The card has a short circuit on the entire + MVDD line, starting from the Q703 element ending with the MVREFD outputs under the GPU, but I will describe from the beginning what I did:

          1. At the very start, I measured the resistances on the main power lines, coils and checked the 0 ohm resistors. Everywhere ok, hundreds/thousands of ohms on each, well except...
