    Philips LED tv 40"

    Hi
    Its totally dead, no lights what so ever. Fuses are okey, nu bulbing caps or so. Got correct ac input. Have tested all components on heatsinks, fets, dual diods etc. I have not tested much on the small stuff on the underside. Some suggestions?

          Post pictures of circuit boards, check and record all voltages on rail connectors on the power supply board and take close up pictures of the connectors.

              If it totally dead and the main fuse is good, then you need to verify that you do have DC Voltage right at the two legs of the main filter cap, we need to have at least that voltage first before going further. Pictures of the board will help.

                  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 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
                  ...

                  Philips 50PUH6400 bad color and gosting / slow motion on one side
                  by Cornito
                  Hello Team,

                  New issue on LCD panel where I need to find out the cause and the potential solution.
                  This is on the Philips 50PUH6400, the LCD panel is an INNOLUX V500dk2 xrs1.

                  I have image, on the right side, the image is more or less normal even if there is a small blur on edge, on the left there is an issue.
                  When moving up and down in the menu on the right the image is slow to disappear, and is darker, like red/brown.

                  I've checked voltages, no issue found comparing right and left side of the panel driver.
                  VHG VGL CKV... are the sames on...

                  Activate power board Philips 40PFH40009/88 tv
                  by spantor
                  Hello partners.

                  Could someone tell me how to make this Philips TV source work without the mainboard being connected? The model of the board is EAX65423701 (2.1) and the model of the Philips TV is 40PFH40009/88.
                  The TV is dead, there is no standby light, however there is a voltage of 12v on the pins ( included 12v VAU ) and 3.2v on the PS-ON pin (see photo) when the power board is connected to the main board. If I disconnect both boards I only get 8 volts on 12v pins. I would like to rule out a fault in the main board by making it work, but so far no one has been able to tell...
