Question about Philips 27RF70S 27" TV
Check for a pot on the chasic board or check yoke if crt.
The problem is most likely you have a bad capisitor or cold solder joint in the primary circuit.
It will look like a half moon shap are dull looking, but look for swollen capacitors first and then cold solder joint second.
a capacitors stores electrons and release them as it need power to the circuit and if it's damage (leaking or swollen it wont ) do so.
Are the regulator break down under a load.
A shorted horizontal output transistor will power up and shutdown with in a few seconds or blow the fuse.
Just a short summary of what's what
