    Re: HP pavillion dv6 wont boot

    I have a similar problem with my HP dv2500. It could very well be a problem with the NVIDIA display chip. They're notorious for bad solder joints that come undone over time and kill the display. Your choices would be to do a reflow of the solder joints or purchase a new motherboard. Reflow is cheap, but there's the possibility that you'd damage components on the board. Buying a new motherboard is less risky, but costs more. Take your pick

    I wish you the best of luck.
    Regards,
    Matt

        In that case, you'd be better off just buying a new motherboard. The joints under the chip are not set up in a way that you can really replace it yourself. You could take it to a pro, but it'd probably be cheaper to just buy a new mobo.

            That's a memory error get the schematic and check for proper voltages to the modules. If evrything seems right replace the northbridge

              Thanks for looking that up. I didn't even think to

              Mine's definitely different then. I'm 99.99% sure the error i'm getting has to do with the video card (chip).

                      It looks like the cpu has an integrated memory controller. Try changing the cpu if the memory slots have the appropriate voltage on them.

                        Hey Matt, I know what you're saying those nvidia chips are a real pain the only way to really fix them is to replace them with a new one.

                          If you want to save some bucks, you better Reball that nvidia chip. Even if you replace that motherboard, you'll get the same problem after certain usage time.

                            Re: HP pavillion dv6 only boot sometimes

                            Hi, my Pavillion dv6 does boot sometimes but most of the time does switch off before getting to boot. I have measured the voltages on the filters and they seem OK, like 3V, 5V and 12V and that is after the power led goes off.
                            Even plugging it in the mains just to charge the battery has the same effect i.e. the power led goes off after a short wile. This particular board does not have an NVidia chip but an ATI so I don't think it has anything to do with the video chips.
                            Any ideas??
                            Thanks.
                            Joseph.

                              It's the same thing with any BGA. The nvidia chips were problematic themselves, but any BGA can get unsoldered from the board. My money is still on the northbridge. Especially if it's AMD RS780M or RS880M, which i strongly suspect is the case in that model.

                                Thanks for the suggestion.
                                I've got a HOZAN spot heater with some heads of the right size so I will have a go at re flowing the chip.
                                Cheers, Joseph.

                                      Hi, I've found a brandnew mainboard for $85,99 on Ebay. Company name is Ascendtech.
                                      Just replaced the board and running as new.
                                      I just used better thermal paste than HP did.
                                      I hope that this will make the difference in performance.
                                      Cheers.

                                        Nintendo Switch Oled HEG-001: Second-Stage Boot Failure
                                        by privato89
                                        Hello everyone,

                                        I'm facing an issue with a HEG-001 motherboard that is unable to complete the Second-Stage Boot. I'd like to start directly with my conclusion, which is the decision to replace the MAX77621AEWI chip, and understand if it could be a correct evaluation.

                                        Before I dive into the process that led me to this decision, I want to mention that I have a fully equipped lab where I can perform any kind of tests.

                                        Let's begin:

                                        Following some guides online, I tried to understand how the Boot phase of the Nintendo Switch works, and what are the...

                                        by hinisa
                                        I'm using Xiaomi Router 4A gigabit edition as wireless repeater. It worked fine for 2 years or so, but last week, wireless started to disappear.

                                        When I unplug/replug the power, it was working fine for a day/half a day or so until it freezes again.

                                        After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:



                                        Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during...

Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...

                                        Hi Team - just joined to see if anyone can offer some expertise in diagnosing an issue with a TV.

                                        I've done a few hours googling and youtubing but just seeing if anyone has any insight here. I got a 55" Samsung UE55MU6470U which seems to boot loop and then after 10 mins will boot, work for a few minutes, then turn off and repeat.

                                        Whilst it's on into the normal Samsung menu/boot screen it looks perfect - so I can't see there being any screen issues. I've seen lots of videos with taping across clock lines to diagnose which particular one may be an issue but i don't...
