Picture issue

[Martin Warhurst]

I have an m8 android box and when used with my Samsung tv never had a problem but if I plug it into my Sony bravia KDL37S550 led tv it's ok for about 15 mins then the screen goes bright green cyan etc and then after 15 seconds goes back to normal. any answers to why this happens?? tia

If you can work your way through this thread you will see that the general conclusion is that some android boxes are not compatible with older Sony TV's. Possibly this is the cause (if your TV is old)

Tv is from 2009?

The thread I linked refers to a Sony Bravia tv was 5 or 6 years old (in 2017).
You could always ask on one of the Sony forums?
M8 boxes are also quite old aren't they?
