    Philips Magnavox PTV775 - AH01..Help appriciated...

    I have a Philips Magnavox that has been in a spare room for a while and i would like to give it to my daughter who will be moving out for her college education. Unfortuately, when i tried to turn it on to make sure it was still okay, i heard a tic-tac sound that is coming from the back part of the TV and no display/sound... in some tries the green led comes on for a blink and goes off again..only thing i hear power related is that tic and tac sound..Any help would be much appriciated..I am some what of a handy guy, im able to do mid-level fixings..Thanks in advance..

    How old is the PTV? Usually Caps in the main power circuit need to be checked. A schematic of the model will help. Do goggle searches on Philips or this link might have what you need? http://www.techlore.com Resources then service manuals

      PTV775 is notorious for the opto-isolator failing in the main SMPS unit. along with the HOT or HV out transistors.

        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 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 43PUS7506/12 - Loud blown out sound
        by aidanmo
        Hello,

        I've got a really strange issue with the speakers on my Philips 43PUS7506/12. It makes this awful loud buzzing now. It happened after it was attempted to be wall mounted - I think the back got squeezed and something broke.
        I thought maybe the speakers got damaged, so I replaced them - no dice.
        • Using the internal speakers, it always happens.
        • Using the headphone jack, it never happens.
        • Using the digital/optical out with a soundbar - it happens after about 2h/movie runtime - it's never as drastic, it just pops in and out, but I didn't want it to damage the sound bar
