Hello friends, I have a 29-inch Admiral TV model tg2900 .. PTNM04-MP chassis ... the problem is that it has a very low volume .. it already replaces the tda with a new one and continues with that problem .. also line capacitors integrated power supply .. I took the voltages that reach it and are 1 = 9. 1v 2 = 9. 2v 3 = 17. 9v 4 = 1. 5v 6 = 5v 7 = 5v 12 = 1. 4V 13 = 17. 9V 14 = 9. 1V 15 = 9V those are the voltages that I took in the integrated tda7297 .. they are almost equal to those of the diagram only in 1v there is a difference in some pins .. I would like to know if what else I can do because the failure still continues .. If you can help me I would appreciate it
