hi there,
to check the line transformer you need first to get his pinout and with an ohmeter check for continuity in each trap and between traps to find any short circuit. an easy test without any schematic is to check for any short circuit between any transformer pin and the output line (the red one). every pin was to connect internally to other, if you find any pin that has no continuity with nothing your fly is open.
to test the crt you may check for continuity in the tube filament (normaly pins 9 and 10 - but confirm with your tv schematic).
in your place i would check first of all the psu, then the H transistor..
hope i've helped.
just make sure there is no MAT before touching anything
best regards, sorh (portugal) |

Thans for your anser, but the problem is that my tv is the kv-14m1e and the chassis is be-4, at least i think so. But i can only find the service manual for the be-4a and this manual is for 21'' tvs, and does't aply for my tv, my model is not listed in the document.
But thanks anyway, do you have any other sugestion? |

if the tv is a kv14m1u then you need a manual for be4/be4a chassis which can be downloaded from
//www.eserviceinfo.com/
try a search for be4 |

I checked all the soldering and they all seem ok. I'm convinced that the problem is with the line transformer, but i don't know if there is also another problem besides that. I don't want to risk buy the transformer and then found out that for example the CRT doesn't work also.
Is there any service manual for this model that i can folow to see where the problem realy is? I had looked in the database but didn't found it.
Thanks. |

Thanks for your reply, then you think that the problem is not the line transformer? It's just because i saw more then one page in the internet saying that for this model when the led flashes 6 times the problem is almost certainly the line transformer. |

6 LED FLASHES CRT FAULTY.
6 LED FLASHES FIELD CHIP PINS.
check the soldering of the field chip at the back |
