    Unplug tv plug back in, turn off lights take a strong flashlight on the middle of the screen and hit power on. Look for any sign of picture, if it's been 1 min and no picture, hit settings button on remote, then look for picture. Report back

        When in stand by there must be a red light on the front. If not the backlight could be faulty but also the mainboard could be the culprit. Easy to check is the 12V on the t-con fuse and many other known voltages.

          No red lights in front but only at the lower side of the panel the philips white logo lit only.the 12v on t Con is missing on fuse .the fuse is good.i am thing the problem is on the main bord.

          Can some one has firmware for this model?

            Google for "55PUS7909 firmware" and you will find a lot of links. When the mainboard is faulty I don't think that a firmware update will help. Most of the times the EMMC is at the end of it's life.

              Yeah William1967 i found one and a try several times with a firmware but still no luck.

              the best way is to replace main board if customer accepts

              Thanks a lot for your help

                Hi Lanada

                The TV main board does it have a Board Number printed on it that starts with "TP" or "RSAG" or a bar code number. If you have not come right yet help me with that and I will see how I can assist. From my experianse it seems like a powersupply fault.

                Here is a link to follow: https://techprofet.com/philips-tv-wont-turn-on/

                Hope there is light after this.

                regards
