    Re: Yamaha RXV 465 no display and power problem

    Also, let me apologize for butting in on another discussion. I just saw a thread on a Yamaha receiver and thought this would be a good place to make an inquiry. Thanks.

      Normally its best to start your own thread, but anyway, what is wrong with the relay?
      Digikey Z5885-ND, Omron G5RL-1A-E-TV8 DC5 might be what you are looking for.

          My kid is bi-polar and she threw the board (Control 2) at me and the top popped off the relay and something(s) came out and I never found what it was.I'm new and couldn't find the actual replacement. Everything I found was out of stock. Thank you for the help!

            Hi R_J,

            Here are further updates on this long Pending problem,

            Upon isolating few components i found

            When L405 was removed, the short remained between +3.3DSP and DGND

            When L409 was removed, the short to DGND at one pin of L409 is gone but other pin is shorted to DGND and when L408 was removed, L408's one is shorted to DGND.

            C488 and C489 were removed of the ckt and tested, they are good.

            So now, either one or more of the SMD capacitors are SHORTED or the DVDD, CVDD and VSS pins of the "No Replacement Part Available" DSP IC ( IC 44 ) is BAD.

            i am afraid if the DSP IC is bad then will i be able to get this changed or is it worth doing it ?

            Kindly input your views.

            Regards,
            Hemant.

              Re: Yamaha RXV 465 no display and power problem

              Finally confirmed that the dsp ic was bad..with shorted dgnd and +3.3 dsp and in an attempt to remove itof the board with hit air gun..i think i have also fried the uP..now its all DEAD.

              Now i will have to keep this aside but whenever i'll come across this model i will try getting its digital board repalced in cheap offers..may be or use its resources as spares for another yamaha model..

              R_J, it was really nice working with you..i appreciate your help and expect the same goes on in furture.

              Thanks again to this forum..

              Soon will be back with another receiver.

              Bye for now.

                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.

                Mitsubishi CNC switching power supply board dead / relay board bad diode failure
                by sam_sam_sam
                I was working on this CNC machine today found no keyboard functioning no control relay powering on
                The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board

                Found shorted diodes on main controller relays there are 3 of them that...

                Samsung TV won't turn on ... keeps cycling the power relay on & off
                by Journey11
                Hi All,
                First time posting here ... my name is Kevin but my friends call me Journey.
                I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
                After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
                It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again....

                Recapping a Denon AVR X6400h SMPS
                by Green Probe
                (TLDR: It was capacitor C6519 [Koshin KZH 50V22uF] and C6515 [Koshin KZH 25V47uF] on the power supply. I have questions at the end)
                Disclaimer: I'm an amateur hobbyist and will get things wrong.
                Always use caution when working around mains power and high voltage capacitors!

                Hey guys, I'm repairing a Denon AVR X6400h for my brother. It quit powering on after a power outage. It acted like this last time there was an outage, but after letting it sit overnight it started working again for a few years. This time letting it sit did not bring it back.
                SYMPTOMS:
