One of India’s four navigation satellites has gone out of service, creating a fresh problem for the NavIC network. ISRO said the satellite IRNSS-1F was effectively lost for core use after its onboard atomic clock failed, a reminder that in satellite navigation, one component can matter as much as the whole spacecraft.

".. orbit raising operations .. could not be carried out."

".. drive signal not reaching the pyro valve of the oxidizer line of the engine meant for orbit raising .. most likely cause .. is the disengagement of atleast one contacts (in each of the main and redundant paths) of the connector."

@Ohsin Do not see "attitude control thrusters" mentioned. Mentioned is "The satellite was stabilised in GTO using its gyro wheels".

May be they try to raise it´s orbit a bit by a "simple" propellant blow down without burning the prop.
