    Re: Teac audio receiver shutting off intermittently

    I tried to clean up that switch but not a lot of improvement. So I decided to remove the small reset pin from the tuner board connector so that nothing can reach that switch. At this point, it's a workaround and not a fix but who cares, system works fine. Only drawback is that I can't reset the system without removing the case. Thanks rievax_60 for your help, really appreciated!

        Did you try with the switch removed but everything else still connected?

            Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
            by tvguy12012012120
            This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

            Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

            Vizio D50u-D1 Dead Set No Standby
            by fharris1977
            Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

            Samsung BN44-00259A standby question
            by Crystaleyes
            Hi all.

            I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
            SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.

            Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
            The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

            Yoga 530-14ARR NM-B781 Ryzen 3 2200 – overheating and shutting down under load
            by Maniackk
            Hi,

            I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).

            The cooling system has been cleaned, thermal...

            Running out of Ideas, hoping someone smart can provide some for my ONKYO TX-SR353 Receiver
            by CDNBrewer
            Hello Everyone,

            I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.

            Symptoms:
            • Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
            • Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
            • I swapped the Left and Right surround
