    42" Philips 42PFL3704D/F7 LCD TV CLICKS BUT WON'T COME ON

    Brought a 42" Philips Flat panel tv. Made in Dec 09. When I hit the power button, it clicks, the white LED light stays on for 8 seconds, then clicks off. The screen itself never comes on at all (not even the "Philips" startup screen) and there is no sound from the speakers. I removed the back and I don't see any bad capacitors. The fuse appears to be good as well. I do hear a VERY slight buzzing noise coming from the power invertor board but I don't know if that is a problem or not. Can someone help? I have a soldering gun but I don't which part needs to be replaced....

      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 ?

      Philips 42" TV 42PFL3603D/F7 clicks but No LCD Backlight
      by jason123
      Hi folks,
      I'm suspecting the actual CCFL or EFL being bad, just not sure how to test, but would like to confirm.

      TV clicks upon plugging in AC. When I press the PWR ON button, clicks again.
      LED on the Main board comes on green (Assuming some diagnostics), Blue LED on the TCON comes on also when I turn the TV on, but turns off about 30 seconds later.

      3V3 ST is on (3.26 V)
      Standy 3.3 V (off) when I press power button goes to 0.16 V
      12Vssb is 11.75 V (on), 0.18 V (0ff)
      +12Voud is 13.8V (on) ~ 0V off
      -12Voud is -12.4 V (On) ~0V...

      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...

      Philips 58PUS6809/12 doesn't turn on - LED turns on for a second and TV clicks
      by Tyrmas
      Hi all!

      A few days ago my TV suddenly turned off while watching Netflix from my media PC. Only connected cables were HDMI and TOSLINK. It immediately started doing this loop where the power led turns on for a second and then turns off. You can also hear a click inside the TV every time.

      I tried the easy stuff first like disconnecting everything including the power cord but that didn't fix the issue.

      Now I opened the TV to check if there are any bad capacitors but as far as I can tell, they look okay.

      I've attached a few pictures and...
