                      Voltage on Big Primary Cap (450v)?

                      Meter set to DCV600 Black to Negative and Red to Positive (Careful HOT deadly side of board, Make sure your hands don't touch anything and don't let the probes slip)

                              Check those 2 stand up white resistor by the copper coils by the ac input.

                                  I checked few things the other day. The was power on the yellow things that cross the line. But only hot side. Couldn't find anything on cold side with any voltage.

                                          This is with the set attempting to power up yes? Does it get above >360vdc at any point?

So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                                                  To all the members here...

                                                  Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                                                  So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

                                                  Hey guys,
                                                  I have a LG 50PJ550 plasma that will not power on.
                                                  When plugged in, the relays click and the screen lights briefly before the relays click again and it shuts right down. It then tries starting up again before giving up and just sits there with the red LED on. Pressing the power button again repeats the process.

                                                  During the moment where the screen is on, there is a slight fuzz that starts to go away as most plasma's do when they turn on. So i do not think it is a panel issue as I get a normal looking image for a split second.

                                                  I have tested the...

                                                  Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.

                                                  It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

                                                  The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

                                                  If I remove the...

                                                  Hi everyone,

                                                  I am dealing with the problem of turning on and off my Dell e7470 notebook.

                                                  The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

                                                  The system does not turn on, there is no post.

                                                  I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
                                                  The problem continues in the same way.
                                                  I tried to turn on the Fn key, nothing came to the screen....
