A50+ does not wake up from sleep mode

My Arylic A50+ does not wake up from sleep mode.
After connecting the power, it works fine. After turning off with the remote control, it goes into sleep mode, but does not wake up. It turns on again only after turning off the power for 1 minute.
On the board, the Q5 transistor in the operating mode is hot, in the sleep mode it is cold.
