      The "pink chip" looks like a fusible resistor - It is difficult enough to follow at a distance
      without throwing in non relevant pictures and queries.
      Please upload pictures using attachment function when ask for help on the repair

        I suggest that you leave servicing to people that have some idea about electronics ,you dont even have the basic understanding ,leave it alone before you kill yourself

          Research, study, test, ect. after you know what all these components are and what they are for, what they look like, how to get the P/N and read the spec sheet, how to read schematic, etc.
          So you want to learn electronics, these items below are just the basic beginning before you ever want to try to repair simple electronics. There are a lot more for me to list, let alone the safety issue (if you cannot identify Primary circuit and secondary circuit, then do not even try working on stuff that is connected to the AC power).
          Just search:
          'What is the fuse?', 'How to identify the fuse' 'How to test the fuse?' 'How to read the fuse rating', 'What does fuse look like', 'What is the fuse schematic symbol', etc.

          'What is the diode?', 'How to identify the diode' 'How to test the diode?' 'How to read the diode rating?' 'How many type of diode there are', 'What does diode look like', 'What is the diode schematic symbol', etc.

          'What is the Bipolar Junction Transistor', 'How to identify the Transistor' 'How to test the Transistor?', 'How to read the Transistor rating?' 'How many type of Transistor there are', 'What does Transistor look like', 'What is the transistor schematic symbol', etc.

          'What is the MOSFET', 'How to identify the MOSFET' 'How to test the MOSFET?', 'How to read the MOSFET rating?' 'How many type of MOSFET there are','What does MOSFET look like', 'What is the MOSFET schematic symbol', etc.


          'What is the resistor', 'How to identify the resistor' 'How to test the resistor?', 'How to read the resistor rating?' 'How many type of resistor there are', 'What is the resistor schematic symbol', etc.

          'What is the capacitor, 'How to identify the capacitor', 'How to test the capacitor?', 'How to read the capacitor rating?' 'How many type of capacitor there are', 'What is the capacitor schematic symbol', etc.

          'What is the inductor', 'How to identify the inductor', 'How to test the inductor?', 'How to read the inductor rating?' 'How many type of inductor there are', 'What is the inductor schematic symbol', etc.

          'What is the transformer', 'How to identify the transformer', 'How to test the transformer?', 'How to read the transformer rating?' 'How many type of transformer there are', 'What is the transformer schematic symbol', etc.
          Never stop learning

              You are right and that is my mistake.

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Assuming...

                Microsoft Surface Pro (5th gen) model 1796 - no power
                by PantherDave
                Hi all!

                I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                Asus Probook P5440UF-XB74 power issue
                by GLISIT
                Hi all,

                TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                Sony Bravia KDL-40V2500 that will not power on
                by PopsCaps
                I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
                I do not hear any sound and I cannot see any backlight.
                I have tried disconnecting every cable on each board one at a time to see if anything changes.
                The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
                My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

                Lenovo 14ALC6 - NMD521 - No power, totally dead.
                by Mike Russell
                Machine won't power on, no power led, no fan spin, completely dead.

                Checked PQ5400 - AONS32314 and pins 5,6,7,8 are 20v (AC adaptor voltage) but pins 1, 2, 3, 4 are 0v.

                Following Gate Pin 4 to PU5400 - BQ24780SRUYR.

                VCC 20v
                ACDET 2.8v
                ACDRV 0v (goes to pin 4 gate of AONS32314).
                ACOK 0v
                REGN 6v

                According to datasheet, conditions are correct for ACOK to be high but it is not.

                Tracing ACOK it's connected to ACIN which is connected to a pin GPB0 of IT8227 but also shown as connected to +3VL via a 100k resistor...
