Problems with playstation

[Helenraeburn]

Was wondering if anybody else had problems with their PlayStation not working on tv that it has worked on for ages. My ps4 will play on other TVs but not the main one in my living room

Hi @Helenraeburn and welcome to the Community

Is it a Sony TV that you have?

Does the Ps4 still currently work on the other Tvs?

Have you checked the connections on the back (or the leads if it won't work on any TV now)
