I bought a Sagem Axium 50 last week and it is turning itself off. it says in the instructions that if the tv is too hot that the temperature light will come on (which it didnt) and it will take a few minutes to cool down before you are able to turn it bk on. but it tok about 20 mins. I dont know if this is normal or if it is a fault. I have tried the customer help line but they are closed due to holidays. Would appreciate any help.
