    Asus Ux51vz no picture

    Hey guys,

    ive got a laptop here with a very strange fault.
    As the title says the Laptop turns on Power Button lights up as well as the keyboard but no picture.
    At first i thought it was a bios issue or a ram issue but the fans are not spinning either (or is this normal?).
    I checked the board and found that vcore 1 from the CPU is good and the other vcore with the two coils has 0.6 ohms to gnd. I found that strange because if the vcore got shorted like from a mosfet it wont have a working Main Power rail.
    Now the Question is: Is the 0.6 ohms normal?

    I remvoved the two coils and the short is on the CPU side... How can the cpu get shorted without any reason?

    At pl8004 there are like 2.5 ohms i guess that is normal but in this post (https://www.badcaps.net/forum/troubl...ux51vz-rev-2-0)

    he says that pl8400 is shorted and the near coils like in my case... But I dont have a shorted ec Chip.

    When the Laptop is turned on the CPU and chipset is getting warm like usual not like theres a short.
    Neither the CPU is getting warm when i inject voltage on the cpu side (1.3v with 2.3 amps)...

      Apple 820-3662 VCore shorted to ground.
      by barry101
      Hi, Would appreciate some help.
      I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
      Get charger light but no fan spin or chime. No liquid damage.
      Found PPBUS and VCORE both shorted to ground. Other rails were ok.
      Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
      With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
      Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my...

      Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!
      by reessi
      Hello:

      I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


      I started on the ACER:

      Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
      All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

      I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

      Un70TU7000b Backlights work, no picture, has sound, panel shorted caps
      by EazyBone
      Picked up this Samsung above thinking it'd be backlights but it isn't. Now MAYBE I'll get lucky.
      Found some shorted caps among the panel boards. Each cap along the line is shorted. On every board (3 panel driver boards)I disconnect each side right and left ribbons and they are no longer shorted caps and have about 1.5Mohm resistance (on left and right boards). The middle board has the main board disconnected and the caps are shorted. Last 4 pics show arrow to caps.

      Now what exactly do I need to do in order to attempt to fix this issue?

      do I have to take each one...

      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
      by Tr0ll
      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

      Original T-con:
      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

      First replacement T-con:

      I thought it might be t-con and ordered new t-con from china(supposedly tested)...

      Samsung UN55HU8550F - No picture, No sound
      by KYBOSH
      Previous owner says this unit powers on and sometime has an image and sometimes not. They attempted to replace the main board but with no success.

      TV came with the replacement mainboard as well as the original.

      When the TV turns on there is no image or sound. No response to the remote or toggle button other than the power button. The power supply's relay was clipping here and there. It did that for several seconds even after I removed the mains. I did this even with no other boards connected (only the backlight was connected at the time). Backlight looks fine but...
