Friends and colleagues of yoreparo greet everyone, I got a samsung tv with the problem that does not fill totally the screen, only a part shows with a stripe in the center of this, also has no audio, this tv have already taken it where another person to repair it and change the yoke which was not his, I have put the yoke that corresponds to this model but still the same, it does not have a problem when I turn it on, I come to you because it is the first time that I face this problem with this brand, I hope and can guide me through the process to find the solution, Beforehand thank you very much

Hello Friend. that # of chassis, is for some colleague to help you with the diagram and what check you have done, or you have not worked because you can check the filter of + and those who are serca of flayback and check the resistances of that same section and diodes and solder flay pins. and reseal all the cold welds you see on the plate. regards

hello colleague: first check the (CR402S of 15nf-x 1600v) if it is in its value or change if there are doubts ... also check (CR403S and CR401S) if there is not one open ... check LR402 and L408 if they are welded well and capacitors associated with these coils ... these (components) are in the stage of (horizontal output) ... this is assuming q, the frequency hor, this within the 16khz ... can also q, the frequency hor, is displaced higher q, the 16khz ... if you have frequencimetro you can measure it in the base of the exciter hor, Q403 and comment .... greetings !!

the solution was to change the capacitor CR403S that according to the diagram is 223j / 630v (22 nanofarad 5% tolerance) and in my case something strange because I did not know if they changed this capacitor but had a 254j / 450v (250 nanofarad 5% tolerance) the case is that I replaced it with the one I had say 254j / 450v and the problem disappeared, it took more than a week that the owner took it and everything ok. in advance thank your attention

Bueno amigo así es la falla esta condensador 254J 250 v  lo único amigo aconsejó es que yo desmonte las bobinas de ampliación una grande y se me olvido marcarla y al ponerle 304J 250v me salía corrida la imagen Asia la derecha  y busque donde esta mi error y intercambie la bobina y eso era  es un mito. Gracia me ayudó la falla y la solucion
