Hello Friend. I already tried putting a dvd. Open if there is image and audio. Cheers
The diagram can be downloaded from this link, it belongs to another model, but the chassis is the same K1.

Dear friends, greetings, you are excellent people, I tell you that the TV is repaired, but I forgot to tell you really, thank you, friends, God bless you all.

which was the fault and how did you solve it?
If when connecting the plug, press the power switch the neon did not turn on, then it has no oscillation. suggestion subject to what teachers think. 1.- remove the horizontal output transistor and place a 75 / 100w focus on the collector to ground, place the voltmeter on the collector, connect the plug, press the switch and check how much voltage it has. comment regards.
Kike you place the tester on a 1000v DC or DC scale. a point to ground of the tube (bare wire that surrounds the tube) and red tip on the pin of the Socket corresponding to G2 (if it is not written on the board, follow the finite wire that comes out of the flyback. That is scrin or G2)
Look there the tension, if you will have more than 300v measure where it says KR-KG-KB. I commented results
companion. The master neg2013 provided the diagram, you can see that the filament (heater) is fed from the flyback through a r257 resistor, of 2w 1.5 ohms. This is the section you have to review. options. 1.- check the line very carefully measuring the components. 2.- arm a vpp probe (peak to peak voltage) in electronic community there is one). This probe allows you to place it on the heater pin and follow the vpp to the kinescope filament. 3.- unlink the filament pin in the flyback and place an external source of 6 Vac. comment best regards everyone.
Hello Felipe. I think when the kike friend makes some tension measurement or some comment that at least he has AV and is kept or scrin at least. We will know if the TV is working and it only lacks filament
Maestro Luis, nice to greet you. You are right. I'm worried as everyone who walks near the flyback, does not comment mr kike how much experience he has. That's how we all started, but you know how unpleasant the issue of flyback tensions can be. however we will wait. Once again a pleasure to greet you and cordial greetings all.
