    LG 47LW6500 powers on but no display

    My LG 47LW6500 went dark all of a sudden.

    Tried power cycling it and the standby light comes on.
    When I try to turn it on, the lights blink in the usual start up sequence but there is no backlight.

    Took it apart and immediately noticed the C603 capacitor had burnt out. I am hoping replacing the cap will fix the issue.

    Complete novice at this, so I was hoping for some advice.
    • It's a ceramic capacitor with labels "R / 471K / 1KV" -- which I understand as 470pF, 10% tolerance, 1000V
    • But the board data sheet lists C603 as 50V and 13pF


    Should I be bothered by the mismatch? Or just find a like for like replacement for the cap?

    Thanks in advance!

    C603 in the service manual is on the mainboard.
    470pF 1000v or upgrade to 470pf 2000v.

        Adding full pictures of power and main board for reference.
        Will be reporting back with results after testing P201 as well.

          Acer Nitro 5 AN515-55-55M1 [GH51G mb] powers on, no vcc_core
          by malogro
          Hello all,

          I'm stumped on this guy, so wanted to see if anyone has any further ideas:

          Intro:

          This is an Acer Nitro 5 AN515-55-55M1 with unknown prior history (bought "as-is" on eBay). It charges the battery and powers on from both AC adapter and battery, so I think this rules out main power issues.

          Upon attempt to boot, it will "reboot" (meaning powers down and then powers on again) only once, and then stays stuck in a status of lights on / no post / no monitor. Powering on with fn+esc maxes out the fans on first boot attempt,...

          Philips 47PFL4606 Powers on, works normal then powers off after a minute
          by simwalsh
          Hi,
          I am new to this forum and have searched for some answers with problems similar to mine.
          Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.

          It sounds like a power supply issue?

          I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...

          Vizio D50u-D1 Powers up no picture
          by csmith
          I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
          Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
          supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
          issue. Set will power up with remote but not power off....

          DELL LATITUDE 5420, ST 20TFKN3, LA-K491P REV:2.0 (A01) powers on and die about 15 secs later, no video
          by Chivo77
          hello friends, I have a DELL LATITUDE 5420---MODEL P137G, ST 20TFKN3 LA-K491P REV:2.0 (A01) and its quite a challenge. It powers on with the battery disconnected, lasts on for about 15 secs, and then shuts off. It does the same with battery only (no adapter). With battery and adapter it sometimes starts after hitting the button several times. It displays nothing in every case. Since only the Boardview is available, I guided myself with schematics similar to this laptop (I'll add them down).Some measurements:

          1- After receiving power SIO_SLP_S0# goes high and never changes.
          2-every...
