Hello all just wondering if anyone knows how to do a hard reset on this model, XVR58C-21D-8CH-V1.1 ?

A) TV initially dead
B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.

D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical... -

The set appeared to be working normally, but it shut down after about 15 seconds,... -
I'm troubleshooting a Philips MDP 3380/12 Blu-ray player that shows no signs of life. The display remains off, and no buttons respond.
Inside, the power supply is working correctly, and all expected voltages on the mainboard match the service manual specifications. The CPU warms up slightly (checked with a thermal camera), the crystal oscillator is functioning, but the reset signal remains high at all times.
The reset circuit appears to consist of two NPN transistors, one driven by 5V VCC and the other by 3.3V STBY, as shown in the attached schematic. Should the reset... -
Hi,
Firstly I'd like to apologize if this was posted in the wrong forum (I'm new here
)
Recently I got an ASUS M5A78L-M LX board in a scrap lot. Saw one broken cap which I've replaced. No broken traces and missing components. While soldering a new cap a bit of solder got onto components bellow SB (opposite of the two lythic caps). Didn't see it and powered the board on.
I was greeted with it not starting. Came back to it a day later and shorted the PS_ON with GND to force it on. It sprung to life but with CPU stuck in reset (it was an FX 4600 I believe). Thats when I saw the...12-14-2024, 10:48 AM
