Turns on, the red LED lights up, when you press power the LED turns green, you see that the screen lights up but then turns off and flashes error 5 (the red LED flashes 5 times, pauses and flashes 5 times... ) | When removing the LED cable from the screen, it continues to flash, when removing the flat that goes to the screen, error 5 continues to flash. This leads us to think that the defect is on the main board, but make no mistake, the defect is on the screen's v-con. shorted smd capacitor | Measure the ceramic smd capacitors, in my case it was the cd9, tsound are 04 capacitors close together, but only one shorted | MIGUELTV |
