This 'relay comm' satellite should be brought to the same orbit and in proximity to the disabled satellite to establish communication. (alternatively, a pre-scheduled payload going via the same intermediate orbit could be programmed to do some relay communication functions in the orbit of the disabled satellite before it goes on to its final orbit).
At a minimum, it can send pictures of the orientation of the GSAT6 satellite and determine how the satellite is spinning/antenna is oriented w.r.t time etc. Once the spin rate/antenna attitude is known, the relay satellite could be positioned to transmit a signal. All of the above applies if it is 'only' a matter of getting a signal into the disabled satellite, which per public domain information is the problem. (If there are other issues, then I dont know). It is not clear what has caused the (i) power loss, and (ii) communication loss (loss of earth lock obviously). The solar panel is deployed, so it does have power from an active power source. Some circuit issue perhaps.
The CT theorist in me speculates that we have just launched the business case for our own space docking/capturing experiment
