    HP G7 no signal but works.

    Hi,

    So I have an HP G7-2272 (MB - DA0R53MB6E1 revE). I hear the nb works fine but I dont have signal (display - HDMI - VGA). I change the southbr (218-0755097) but same issue. I have and another G6 with the same board but with UMA, so I have the same problem.

    Does anyone seems the problem to fix it?

    I attached the shematic.

    Thanks.

                      EIZO CX270 - No signal but Backlight and Panel works, logo works, admin menu works. OSD doesn't. What?!
                      by vf fa
                      Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

                      I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

                      So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.

                      Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
                      by AstutePauciloquent
                      Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

                      I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

                      Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel

                      Failure Symptom



                      No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                      Where is the short?

                      Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



                      Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

                      Good morning.

                      I have posted here before and have gotten AMAZING advise (thank you!). I'm back for more. This BCaps Sub Forum is so well attended I thought I would post here.

                      This question is for an automotive application but has to do with what are essentially electrical questions and problem solving... If this is inappropriate I get it. Feel free to delete it or move the question.

                      Dell ATX PSU won’t start, but forcing it works fine?
                      by CapLeaker
                      Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

                      Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...
