    Philips 37PF9975 shuts down after 30 minutes

    A Philips plasma 37PF9975, starts up correctly, everything works normal, for about 30 minutes. Then VA and VS supplies are shut down.
    Eventually other voltages will disappear aswell.
    Set can be put back to operation after powercycle mainscord.
    Is there a known issue with those powersupplies?
    Cap issues should give another symptom, like hard to start etc
    Appreciate any advice,

      Philips 47PFL4606H/12 turns off after 10 minutes
      by ressof
      Hi

      I have a Philips LCD 47PFL4606H/12 that turns off after around 10 minutes and then i cant turn i back on again without removing the power cord and attach it again. Then it turns itself off again after some minutes. When this happens the red led that usually indicates standby mode is off.

      Can it be the same problem as in this thread?

      Philips 42PFL3609S/98 Shuts down after sometime
      by vernond
      Hi.

      I have a Philips 42PFL3609S/98 TV that shuts down after some time. If the TV is not power overnight and is powered on in the morning then it will last longer sometimes up to 2 hours. After the first shutdown, it will be more difficult to switch it on again. It would be easier to restore power if I remove the AC cord and plug it back again.

      Replacing capacitors C805 and C804 didn't solve the problem but made the running time last slightly longer. The old capacitors were giving me a reading of 920 uf. C840 and C840A are giving out a reading of 72uf and were not replaced....

      Philips 32PFL4901/F8 BA4GF0F0102 2 Not getting standby led
      by alro7779
      Hello, guys!

      The same 32" Philips TV I was having video issues, but now I don't have standby led at all. Someone here shared with me the schematic of the power supply, and checking the voltages, I see right after the resistor R604 I'm getting 1.6 v which is too low for enabling the Gate of the Q601 mosfet (the diagram says 4.2). On the R614 resistor I'm getting 181 V in and 117 V out, then through R603 I'm getting the same 117 V in and 59.9 V out, finally getting the latter voltage in the R604 BUT getting just 1.6 V out, which is the voltage that goes on to the Gate of the Q601...

      Philips 8200 series 65PUS8204/12 stuck at Philips Logo
      by G33RT
      Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

      It does power up when pressing the power button.

      I already try the power button while plugin the plug with no result.
      Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

      Could this be an PSU or eMMC issue ?

      Lenovo V15-IIL motherboard swap (in V15-IKB) shuts down when internal display is connected
      by Giggle2562
      Hello everyone,

      I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.

      The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.

      Here's what I've tried so far:
      • When the internal display is disconnected, the laptop works perfectly fine via HDMI.
      • The laptop shows an image on the internal display for a few seconds before it shuts down.
      • I tried swapping the LCD panel with a known good one.
      • I tried swapping the LCD cable
      ...
