It turns on normally for a while and turns off. then it doesn't turn on anymore. | I found the capacitor in position c5817 at the power supply, exhausted. It was replaced and the sound worked normally again. | Carlão | |

TV turns on LED turns white and the display does not light up | Ic403 (mp2212dn) | In the absence of it, I inverted the ic403 with ic407 to test and it solved the problem (it did not generate voltage inv_on(2.8vcc) normal voltages with tv on: 1=0.78v, 2=ov, 3=3.27v, 4= 4.67v, 5=3.25v, 6 and 7=1.44v, 8=3.22v and the only different voltage on ic407 is p6 and 7= 1.83v | |

Turns it on and within seconds the screen locks, that is, the image freezes if I was without an antenna, the chisco remains frozen, sometimes the image disappears and the OSD becomes a dark black screen, it freezes the functions, it seems like cold soldering on the BGA or the technician thinks it could be t- con or even the display. | Replace o c414 10uf 16v, o c829 330uf 25v eo c889 330uf 25v | Replace the c414 10μF 16v, the c829 330μF 25v and the c889 330μF 25v, replace the filters and run for the hug! | OSÉIAS |

LED turns on, all voltages ok, has backlight, has audio, but no image | Tcon - 12v fp1 fuse open (I read in another topic that it would be 3a, I'm not sure), cause: capacitor cp47 (10uf ??v) shorted, I removed it and the 12v line went up. I took advantage and, prophylactically, I also replaced its twin cp46 (same specification and are in parallel) with a 22uf 25v electrolytic capacitor. apparently it is a common defect in this tcon, if you search you will find several qp2 transistors (power mosfet) charred because these capacitors short out and lead to the fet. I was lucky because my QP2 was good. good repairs! | 2000 | |
