Question about Philips Magnavox 27MS343S 27" TV
I Allready check the resistance R344O (10 ohms 1/3 w) at the CRT circuit board and it is good, I did this because a technician told me
that maybe the problem, He told me too something about an arch in the CRT, will you please help me.
The model of my tv is R27TNTN and I never find information for this model. Tankyou again, Roberto.

Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

It sounds like the voltage regulator in your power circuit. Also you have a capacitor that's going bad somewhere and won't hold a charge. That's why the picture is fine for a while then turns green. Unless you service TV's this one will have to be brought into the shop. Unfortunately it'll cost more than the TV is worth to get it fixed unless it's still under warranty. These days TV's that small aren't worth fixing. You're better off buying a new 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
