It turns on a red screen and then turns off | Voltage increase on pin 56 of tda 9570h/n1/ai1012 | Dear colleagues, this TV has this symptom when turned on, it works, the screen is completely red with lines of retraces and then it turns off, checking the RGB line I found a voltage of 8v coming out of pin 56 of the TDA 9570h/n1/ai1012, as others on pins 57 and 58 were normal as indicated in the scheme, to check if this voltage was actually coming out of the tda, I raised the resistors 3201, 3202, 3203, both 100r, and this increase in voltage on pin 56 was confirmed, thus confirming the Defect in the TDA and with its replacement the TV started working normally again, I hope it can help some colleagues. | |
