Keeps turning on and off then turns off completely red LED flashes 6 times | Tsound are 5 soldering points on the output of the IC9500, the return of the LEDs, the voltage must be the same or otherwise the protection will be turned off. | Changing the bars is correct, but jamping the point that is lowest, the voltage stays the same, so it doesn't turn off, but you can break a limb until you replace the bars. | Beto2828 |

The TV turns on and works normally, however...if it is turned off and tries to turn on again, the TV gets stuck at the "always" logo and returns to STBY. | An increase in the supply of 1.5v was detected... the transistor (1117-1.5) regulator (n801) of this line was supplying 2.41v. | Replace the regulated one (n801) 1117-1.5 with the same one. good luck! | evando viana |
