Happy late colleague for everyone, I am repairing this philip chassis tv 25b800-7562 .. this colleague tv turns on and looks very nice but after half an hour it turns off, you turn it on and on again it lasts a good time and then It goes off, I noticed that as it warms up it lasts less on, check the filters all look good, resorder the most vulnerable part as the source, try to see if it uses any protection, this tv uses in the jungle the, tda8373c, any ideas please my colleague ,,, grace
