Hi Jose Luis, thanks for your time.
I tell you if I change the regulator, flattening filter, optocoupler, power swiche transistor, and I measured each component of the source of the hot stage, I change the filters of the secondary of the source, the transistor A1015 that works with the optoacople. I want to add something, when I read in the primary stage source in one of those that I am with the tips of the multimeter the source starts at the moment to another. I deduce that the fault is still at the source.

I do not have the diagram of this model I looked for it on the internet and could not find it, it results in the datasheet of the tv microjungla ic. One of the difficulties to be able to face the fault in this TV is not to have the diagram at hand. I still count on you to dump your experiences.

I agree with you that the problem must be at the source. Did you try changing the diodes of the secondary of the source? Sometimes they usually have intermittency problems even if they score good.

Hi Jose Luis, I commented that I could not find the solution with the source, I had to adapt a 5v source in the secondary stage with that works without probes. Thank you for your dedication and follow-up on this case.
