The sonde was on the forest ground. When i found the sonde, the burst killer had about 20 minutes left and everything was working. After when i got home, i was turn on the sonde for a fast test, and the green led was blinks twice and then the red led was starts continous blinking. After this i was start the decoder and everything is work except the gps because the sonde only sees 3 satellites at most, from my window. Has anyone ever encountered a similar error?

Red blinking LED means the sonde has failed its self-test. It's likely the temp sensor has snapped upon landing.

The temp sensor is ok. The sonde measures properly temperature, humidity and air pressure. The sonde strongly hit the ground. My first idea was, an smd part detached from the pcb when the sonde hit the ground, but i dont see anything on the pcb.

It would take a few minutes to test the sonde outdoors. 3 GPS satellites are few for RS41.

Red LED will also blink if battery is low. If you found sonde just before it would have turned off and all sensors are ok, it's likely reporting low battery error.
As for the GPS, try it again in a free space outside (like on the parking lot, garden, ...), not just outside of an window. 3 GPS is quite low, but if you were really unlucky, other 8 might have been behind your house or unusuable due to multipath and reflections.

When i found the sonde the battery voltage is 2,7V and the burst killer countdown had 20 minutes left. I dont know how many volts the low battery voltage limit. At home i replaced the batteries. And now I tried the sonde outside, and the GPS is working properly, but the red led is still blinking and all sensors are still ok.

In Prague, in comparative tests of the reuse of returned sondes, low battery capacity was signaled on some pieces.
After replacing the batteries for re-enrollment, it remained, but the probe still measured normally even when the LED flashes red.
