I received this home theater from a client who wanted it checked by a tech, I applied the power and noted there was no sign of life.
I opened up the machine and proceeded to scan the whole system, beginning with the power board and later motherboard.
I noted two capacitors with top part slightly swollen on the power supply section, usually if you get a capacitor with top part swollen it is advisable to replace it directly with testing.
I proceeded to the mother board and found two capacitors with outer cover ripped off and one with top part slightly swollen as you can see below.I decided to replace all capacitors with the same capacitance value but higher voltage rating to avoid come back.
After replacing the capacitors I applied power and the machine came up smiling.
