I've some what similar situation. After my renovation, I tried to test the cable point with my cable modem to see if it works. Tv signal is ok but digital signal very bad hence cannot surf internet or use digitial voice. I have not done anything with the main tv point. I called starhub regarding the problem, saying that my i need to activate the connection or check ch 743.25. I borrow tv from my neighbour and checked that it is already activated. So i called Starhub again, this time they sent their guys to check and found out that the cabling from the Tap to my home is faulty. They say they would replace the cabling from the tap to outside my door for free BUT i will have to PAY if the cabling in the house is faulty too. I thought $150 for additional connection but I'm not adding any new connection. Is this fair? I have done nothing to the cable point, yet i"ve to pay if found faulty. My flat is a refurbish flat that i got from HDB. Who should i refer regarding this?
