    Toshiba 46g300u3 screen turns off after hours

    Toshiba 46g300u3 screen turns off after about 2.5 hours. The power light stays on and the chrome cast I have remains powered. Sound does not continue also the backlight is off. The TV will turn back on immediately and stay on for another 2.5 hours. When it goes out the screen turns off followed by the sound 3 seconds later.

      Sounds like something is overheating. When it turns off take the rear panel off and direct cool air on the boards to try and identify what may be overheating.
      Willing to help but I'm no expert.

          My thought was if it was over heating it wouldn't come back until cool. It comes right back on no issues

              Do you still have all voltages when it turns off?
              I assume no responsibility for any stupid suggestions I might post.

                  Is there some kind of automatic power down setting in menu?

                          It's not automatically turning off. That setting is off. I'm not at home I'll get voltages then.

                              Hi,

                              I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                              by Rav_tangle
                              Hi all , thanks for having me & I think this has been asked before but my case seems a bit odd.
                              I have a MacBook Pro , board 820-2915a and it turns on , chimes etc etc , keyboard lights up, fans spins , can turn caps lock on/off but screen is dead.
                              Iv tried the resets , shine torch through back logo , nothing , it seems the screen has no power. If I plug charger , it charges but if I disconnect battery it displays green light but won't turn on. Iv tried screen on with another board & it works & seems I'm not getting any voltage at pin 2 , next to ground pin .
                              is this...
