Hello forum people. The problem with this TV is that it gets to stand by but when the power button is pressed and tries to activate the high fuse is blown. it is an mc-14a chassis Ts source: C4429 + 1 TDA type that I do not see (the numbering gives to the traffic. TSH: D1555 Diodes at source and resistors in order. Filters in order too .. any suggestions of x where to follow

When the fuse blows it is the short-circuited diode bridge or c4429 in short. The integrated source TDA4601 usually burns that transistor. Check those components outside the board. Greetings

Thanks for answering Victor
The diodis bridge works normally, the same c4429 (without problems), in fact the source enables standby normally, it is when it goes to high activity that flies

The stand by works with the secondary source, that of the small transformer. The problem is in the source of the tda4601. greetings
