Weather sensor Vaisala PWD22 reboot.

[zebu]

Hello ! Please tell me, has anyone repaired the Vaisala PWD22 weather sensor? Reloads randomly. Through different times. It can work for several hours, or it can reboot every minute. Replaced capacitances in the power supply. Tantalum capacitors on the board too. There is no stable ripple power supply. Replaced SDRAM. Still constantly chaotic reboots.
