    W trybie SDM masz ten error22 ?
    - w stby Led miga x2 dwa razy to nic nie znaczy
    * zazwyczaj jak wejdziesz w SDM to error 53 (NAND)

    Przy czym może to być:
    - uszkodzenie CPU, zasilanie np. 1.25V, inne zasilanie 2,5V
    - wsad NAND, ..... ?

    Back-up Software Upgrade Application If the default software upgrade application does not start (could be due to a corrupted boot sector) via the above described method, try activating the “back-up software upgrade application”.

    How to start the “back-up software upgrade application” manually :

    1. Disconnect the TV from the Mains/AC Power.
    2. Press the “CURSOR DOWN”-button on a Philips TV remote control while reconnecting the TV to the Mains/AC Power.
    *(attention : not supported by use of RF4CE remote due to the fact this application is not running yet at the time of the “CURSOR-DOWN” request ).
    3. The back-up software upgrade application will start.

    In this case, replacement of DDR memory can also help, as long as hynix companies are used.

    Error 53 in SDM mode.

    Added after 1 [hours] 30 [minutes]:

    In SDM mode, I connected to the network with the down arrow button pressed and the TV came to life.
    I'm testing for now.

    Unfortunately, I have to withdraw my post about dramatic memory because my play came back with the same symptom after 2 weeks :(

    It may also be the case in this case, because tv froze the image for a while, a strange pixelosis and restart appeared. So the damage is probably "maturing".

    The next day the problem returned. At the customer's request, I replaced the motherboard, which restored proper operation.

Users suggest that the issue may stem from a faulty CPU or NAND memory, with error 53 appearing in SDM mode.

Ultimately, replacing the motherboard resolved the issue, restoring normal functionality.
