      I have to find yet a service manual for a sound bar. If it has a OLED display, it might be that. Other than that probably a shorted MLCC somewhere on the board is quite often the cause on these Philips sound bars.

          Philips HTL6140B/12 SoundBar no power
          by StasNep
          Hello

          I have got a defective Philips HTL6140B/12 SoundBar, no power from button or remote.
          The power supply is external and working correctly, even tried another one.
          Checked caps with esr meter and all seems ok.
          Checked various resistors and smd capacitors and they seems ok.

          Please help to diagnose this SoundBar.

          Thanks ...

          Philips 8200 series 65PUS8204/12 stuck at Philips Logo

          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 ?

          Philips curling iron - is this a common AC cable?
          by double_DD
          Hi all,

          Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
          As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.

          Not sure if this is something Philips proprietary, or a standard, but the cable plug...

          Philips 47PFS7509/12 LCD TV problem
          by janos6662000
          Hi

          I have here a Philips 47PFS7509/12 LCD TV which came to me with a weird problem : without signal i could access menu, make a factory reset, access menus, etc.
          When i applied cable signal to check image, i had normal picture, but TV was restarting.
          I downloaded original firmware and applied the update, but the problem remained.
          From a colleague i received a "factory package software" which is a lot bigger.
          I made another firmware update, but still did not solve the problem.
          Somewhere on the way the error got worse, because at the moment the...

          JBL Soundbar 2.1 Deep Bass PSU No DC Power Output (Detailed, w/ Schematics)
          by _AcE_
          I have two of these soundbars, both with the exact same issue. The soundbars were hit by lightning and no longer power on. The PSU does not output any voltage on the DC side. When plugged into mains, the DC output is a stone-cold 0.0 volts. The AC side of the PSU seems to be functioning correctly (as far as I can tell). When checking the plugged-in PSU with my thermal camera, the OB5269CP PWM controller (U1) and the two resistors (R12 and R13) pulse on and off. These run to the positive DC side of the bridge rectifier (among other components along the way).

          There's no physical damage...
