This TV Sanyo Ds27800 model 27800-02 does not turn on, it does not have the 5 v in power button, in ± B it has 15 volts and the ceramic resistor that by one of its ends joins the relay is overheated, if someone can help me we really appreciate it because I still lack knowledge. 20180507_071936.jpg [3.45MB]

Thank you infinitely Francisco Vallarta for the diagram you gave me you can find the flaws of this Sanyo TV model Ds2780 chassis 27800-02 I share what I found in case someone serves, I changed the horizontal because it was short, I did not activate the relay and I changed the D683 that goes right next to it. I switched on the TV and it activated but it gave me a bug, it didn't turn on the filaments, I changed the c484 of 50v / 4.7uf and turned on with the red screen and opened only halfway, up and down in black, all the voltages in the IC LA 7841 were fine except that of leg 7 of 3.2 v. I changed the C502 of 35 v / 220 UF the TV turned on but there was still another fault, the screen went dark as at 30 seconds for protection, I measured voltages in the opto coupler and right there was the problem, the resistance R619 that goes to the leg 3 was altered and at which 605 a high voltage arrived and since this is an error amp it turned off said screen. I changed it and TV ready. Maybe my explanation is not very good but I share them with joy.
