    TCP42ST30 6 Blinks

    I have a TCP42S30 that uses a TNPA5349 with 6 Blinks. I check the SC2 Connector with both probes and it displays 120K ohms. If the board was short then it would show .03 Ohms. I checked the Mosfets to see if they were short and they were not. Any tips where to start?

      Found a short on Q441 DG302. I will give an update once it's been replaced.

          Buy a screw update from Shopjimmy. They have lock washers to prevent another failure.

                      Extreme High Current & Low Voltage Short Killer ??
                      by DynaxSC
                      Hi Folks

                      I'm looking for a extreme high current short killer solution for a reasonable cost.

                      I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
                      After taking off the socket, the shorts dissappear again.
                      The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

                      MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
                      by Stephen
                      I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

                      HP Victus 15-fb dag3pamb8d0 Short on VCORE – How to Confirm CPU Fault?
                      by adelfr2009
                      I have a laptop HP Victus 15-fb with motherboard DAG3PRMB8D0, CPU Ryzen 7535HS, and GPU RTX 2050. The laptop has a power issue: it does not turn on at all, and there is no light on the DC jack.
                      After inspection, I found that an NMOS near the charger input had a short. I replaced it, but the short remained on the 19V line. I checked the charging circuit and it was fine, but the short appears after the current sense resistor near the charger. The charger does not pass current when connected, so I inject 3V–4V after the sense resistor. No component gets hot, except the CPU which becomes...

                      Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
                      by Victor Moreira Silva
                      Hello everyone,

                      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

                      Well, my decice specs are the following:

                      Model: Acer Nitro 5 AN517-54-55T5
                      CPU: Intel Core i5-11400H
                      GPU: NVIDIA GeForce GTX 1650
                      Motherboard: GH51G LA-L181P Rev:1c

                      The symptom:
                      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

                      HP Omen 15-dc0001nh capslock blinks 5 long and 3 short
                      by Tom_x
                      Hi,

                      I have HP Omen 15-dc0001nh (DA0G3DMBCE0 rev: E) with blinking capslock 5 long and 3 short. Fans spin constans speed.

                      HP worked for 2 months after i repaired (before damaged by thunder via rj45 port) I removed LAN ic and powered on

                      Now with blinking capslock:
                      All voltage present on big coils, except +VCCGT (i don't know this need for booting)

                      I tried re-flash bios with known firmware- same result (now i don't have spare bios chip to test spi flash failure)
                      DDR4 ram is ok, tested on other laptop
                      WLAN and SSD removed,...
