Does not tune in to any digital channels | Tsound was a power outage and after that no digital channels came on. Go into the menu and restore factory defaults and nothing helped. Remove the varicap to measure the tension and it was normal. I put the varicap back together and tuned again and, oddly enough, the channels tuned in. I don't know what happened, if this tip worked, the TV started working normally again. It must have failed when the power went out. | I removed the varicap, I did the tuning without the varicap and then I put the varicap back on and the tuning went back on | ADRIANO MIRANDA |

Normal TV but suddenly it turns off abruptly or gives a green screen with vertical lines, a typical screen defect, it locks the controls via remote and keyboard and after this less than 30 seconds it turns off. | You see, I turned off the TCON, disconnected the inverter board from the LEDs and disconnected the keyboard and PCI from the remote receiver. Even so, the TV turned off, so I changed the power supply covers, all of them and nothing. conclusion main board defect... but when the new board arrived, surprise, the same defect. | After days, luckily the TV turned off and I pressed power on the keyboard and remote and the TV did not turn on, analyzing the power supply I concluded that the q5 (bc848- smd) of the power supply (mp116-ch) was not switching ps_on, I removed it and measured and I found no fault, but I decided to replace it and that was enough to solve the defect. a momentary short/leak between collector and base was enough for this voltage to affect the main board and cause the processor to freeze, which is why it gave a green screen... | MIGUELTV |
