    Philips 32PFL7782D/05 LCD TV won't turn on?

    Hi peeps.

    I have a Philips 32PFL7782D/05 LCD TV that won't turn on. The LED gives one long flash followed by two short flashes. According to the manual this is error code 12 - I2C error while communicating with the MOJO PNX8314, which is obvious because the MOJO on the main board isn't receiving power to communicate with IC 7H03.

    I checked the PSU for bad caps but they're all good. So I connected it all up all the boards and powered it up the TV worked fine. I switched it off turned it around, so the screen was facing me, and powered it up again and its refusing to work.

    So I looked at the PSU again and realised that the 12V supply fails to rise when you turn the TV on, it will rise to 120mV and shut down again. The PSU board is supplying 5.2V to the main board and the PSU is receiving the 'On' signal from the board but the main part of the PSU won't turn on. The PSU is a Delta DPS-182BPA

    Any ideas on this one?

      I've had a second, and third, look at this set and I just don't know if the PSU or the mainboard is the problem.

      The main board is sending 3.3V to the PSU ....

          Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

          Philips 65PUS8518/12 distorted image after main board replacement
          by tuner2000i
          hello everyone,

          I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.

          The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

          Philips 47pfl6008s wont turn on
          by JorKsX
          Hello. Got my hands on Philips 47pfl6008s/12.
          Problem is that it does not turn on. Last owner said the problem came slowly.
          One day did not respond to remote, had to unplug from AC and then back and it worked. next day had to disconnect 3-4 times before it turned on.
          And then it went into hours of unplugging and replugging until it turned on.
          When I plug AC into tv, it does not respond to "turn on" button or anything else.

          After 10-15minutes the TV starts blinking red LED twice.
          So it blinks twice, then waits 3 seconds, then again twice...

          Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
          by cheeky2
          I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
          Obviously the same LVDS connector for the screen connection...
