    Sanyo DP46840 Shuts off after a few seconds

    Hello, Im trying to get a sanyo DP46840 up and going. It comes on for a few seconds and then goes into shut down mode. When this happens the audio will go out first then the backlighs will turn off and the whole set goes into shutdown.

    I made a video showing the audio voltage dropping when this happens. I think it needs a new 13 volt IC chip.

      Side note. If i turn the volume down the set stays on. So it has something to do with the 13volt audio circuit. I would say its the IC everyone has problems with.

          Look at the PSon voltage. If it disappears, the PSU just shuts off. and I second the audio ic.

                  Lenovo Legion Slim 5 16APH8 (RTX 4070) - Turns on for a few seconds then shuts off. BIOS issue.
                  by riko 656
                  Hello everyone,
                  I need help with my Lenovo Legion laptop. It turns on for a few seconds and then immediately shuts down. I believe this is a BIOS corruption issue.
                  Laptop Model:
                  • Model: Lenovo Legion Slim 5 16APH8
                  • GPU: NVIDIA GeForce RTX 4070
                  • Main BIOS chip size: 32MB
                  • VBIOS chip size: 16MB
                  Problem Description: The laptop was working perfectly. Now, when I press the power button, the keyboard lights up and the laptop powers on for just a few seconds, then it shuts itself off completely. After researching, I am convinced it's a corrupt BIOS.
                  What I Have Tried So Far:
                  1. I

                  I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
                  Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...

                  ASUS B5402CEA – Laptop powers on for a few seconds then shuts down
                  by riki_22
                  Hi everyone,

                  I’m working on an ASUS B5402CEA notebook.

                  B5402CEA_MB_R2.2
                  HA4YT LA-L861P
                  REV:1B

                  The board powers on, fan spins for a few seconds, then it shuts down by itself.
                  I suspect the BIOS might be corrupted.

                  Could someone please check and clean (repair) the attached BIOS dump?
                  I’ve also attached a few photos of the motherboard for reference.

                  Thanks in advance for your help!

                  Panasonic National NV-M3 VHS Camera shuts down after some seconds
                  by APOPAP
                  Hello everybody,
                  First post here. I have been reading posts here for some time now, but today I made my first account and post.
                  The same question is also posted on another site, here it is:

                  Just found an old Panasonic National NV-M3 VHS Camera without the original charger but with a special bag with a led, switch and fuse that is designed for a lead-acid 12v 6Ah battery. It has two cables coming off the bag that leads to the camera terminals (Only + and - ). Pretty sturdy design I think.

                  I tried connecting it to a Computer PSU (12.7v) but I get battery error...

                  Sony LED 65X9005A shuts down after few seconds - looking for help
                  by tec3000
                  Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

                  I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...
