Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
Thank you very much budwich i wil do that, but after read all post in this thread i realise my problem is the 13.2 volts from the power suplay because if i remove all display (panel) flat cables i get the same error code 2-5 so i realise if i start the set and mesure the output voltage from the PS i should get 13.2 v right and yes i get it but in two 3 secounds they start to fall to 12.8 ~ 12.2 v and finaly when the set turn on the back lights they go to 11.5v and the set goes off all this with the flat cables from the main board disconected and conected are the same readings i change main bord to the old one i have and same results so my conclusion is i have probably some voltage regulator or some output capacitor failing i guess. Before i open a new thread please i like to ear your opinion.
Thanks very much to all people from this thread.
