      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 ?

          HP F4180 stopped working please help troubleshoot
          by flat-earther
          I was doing a large print job with my HP Deskjet F4180, and after about 50 pages the printer stopped in the middle of a page and the black ink light started flashing.
          So I went to refill the black ink cartridge with a syringe, but found out it still had a lot of ink.

          I tried to print a page again but every time it would print only a bit of the page and immediately stop with the black ink light flashing again.
          I tried two other black ink cartridges, and the problem still endured, so I knew this problem had to be with the printer itself.

          I ran HP Print and Scan...

          Philips HTL2160 Soundbar bad audio crossover fix
          by Per Hansson
          Bought this for my folks as a Christmas present what felt like recently but it's actually been 6 years already!
          The audio quality has successively become worse to the point that even my mom said it was unusable now, and I had to agree!
          I have had it open before to add a secondary coax to optical converter for an unrelated issue with audio dropouts when hooked up to a Dreambox that it had since it was new.
          Back then I noticed the craptastic choice of capacitors, and I was not really keen on replacing them all if it would not fix the issue, which I was doubting would be capacitor...
