It is far in appearance, but not really ...
Good evening dear Juan Cortes ... I see with sorrow that it happens to be a persoma like others that give solution to other colleagues, but I am pleased that I am right ... I tell you my experience with this fault, other colleagues the they will have solved otherwise, I don't know ... Enter the workshop a TV I do not remember the model, I can not go after several notebooks back to give more precision to my story.
But the chassis is the L03.2L.AA, well enter this TV from a customer with several failures, including the most important in my opinion: Veritical compressed with dashed lines at the top
of the screen ... From experience I know that this is due to deficiency in electrolytic capacitors in the vertical, this can be in any other chassis of any other TV ... Repair the failure of the vertical stage, but the failure of the audio that I had a very low volume and that after 10 minutes I was very fond of finding it hard to solve ... Look at everything, check the entire audio stage ... But in the end this 2444 condenser catches my attention because of its medium rare color , all the other capacitors in the chassis were all blue, except this one that looked gray,
as if it had been drowned or something like that ... I removed it and directly replaced it and zas! the audio fault is solved ... I don't know if it is by chance, rather because of how I am, "the unusual thing has to be the cause of the failure", it costs nothing to try ... My advice is to use 105 degree capacitors, ah this fault always comes back, as well as the vertical failures caused by the exhausting capacitors ... Good luck ... My regards
