Damage from Lightning through Comcast Coaxial Cable

On July 12, 2024 we lost Comcast service as a result of a lightning strike (we did not lose electricity).  Support opened ticket [Edited: "Personal Information"] and sent a technician who checked all Comcast equipment, splitters and outside lines.  He told us another tech will be out 7/13/24 to replace damaged outside lines which should fix our issue.   On 7/13, tech replaced Comcast lines which fixed all issues with the exception of:  our main TV and AV receiver both of which were connected to the Comcast DVR box via HDMI and were plugged into surge protector strip (we also have surge protection on whole house electric).  Our main TV and AV receiver will not turn on and were told by your tech that they are both "toast" and will have to be replaced.  All other TVs and our cable modem box were not damaged and are working properly.  We believe that the surge from the lightning strike came over the Comcast coax and hit our main TV and AV receiver causing irreparable damage.  Therefore, Comcast is responsible for replacing these two pieces of equipment since you did not protect the coaxial input and we would like to know how Comcast can make us whole?  We have been a Premium Comcast/Xfinity customer for many years.  Thank you.
