Try to flash an original eeprom to the set and see, may be its just a software problem... if still no network, tell us how it happen, power on already no network or network disapear when the led lights off....

NO NETWORK ,,,,

you have to measure all uplink and downlink path with all "VR-x" supply !
and all control TXP by MCU to Hager, TXC by COBBA/UEM to Hager , and VCO LOOP!

also ANT switch control by Hager !!

do not try to make more damage from test and replace parts !!
