    Sanyo dp42647

    This set has a backlight issue. it has a picture for 2 seconds then goes black. It has sound. I found fuse 102 on the long board on the leftside to be blown. Any suggestion?

          Test the Mosfets that run the vertical length of the board you will probably find some shorted.

              You have two inverter boards, Master and Slave.
              http://www.shopjimmy.com/catalogsear...=Sanyo+dp42647

              You need to get the P/N of those 8-PIN Power MOSFET (there are 8 of them in the MASTER Inv BOARD) to check the resistance between S and D pins.

                      LG 47LB5DF blown power supply board
                      by cmlewis89
                      Hi folks,

                      I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...

                      HP X360 convertible battery blown fuse error, not charging
                      by drscoot
                      HP Modelnumber: 14-dh0061nb​
                      This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
                      The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
                      I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
                      And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
                      All these 3 batteries are charging...

                      Identify blown component on HP ENVY X360 13-arxxxxx, Motherboard G1 13 AMD X360 18740-1 448.0GA03.0011
                      by w00pz
                      I have blown a component on HP Envy x360 with motherboard G1 13 AMD X360 18740-1 448.0GA03.0011.
                      Unfortunately there are no schematics available and the component was so blown the marking weren't readable.

                      I have marked it with a red circle in the attached photos - sorry for the mediocre quality I was too much in a rush.
                      Hope someone will be able to identify the component.

                      Many thanks for your help!

                      Part selection for possible blown inductor on ASUS GX531-GW-AB76 laptop mobo
                      by swerg
                      Hey everyone,

                      I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
                      I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
                      I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components...

                      What problems could this blown cap cause in a Marantz SR5400?
                      by ohren
                      I'm looking at a vented C513 in a Marantz SR5400 (photo included), in the FR section on page 24 in the service manual (https://audiocircuit.dk/downloads/ma...400-avr-sm.pdf).

                      R533 right below it in the photo is charred, but measures the correct value.

                      1. I'm not familiar with amplifier circuits (at all — don't know the difference between classes, etc.) so I was wondering what problems would manifest from a supposedly non-operational C513? I didn't hear anything odd when testing the output channel with a speaker. Is there a simple test that can be done...
