Hi, There seems to be a problem with the receiver's converter circuitry. When I press the power button it won't turn on but I don't know how to check it.

Does anyone have a schematic and how to solve the problem? In dire need of everyone's support. Thank!

What makes you think that? Have you done all the 'simple' checks i.e. fuses, the switch itself? Beyond that it will require dismantling, a test meter, the understanding on how to use one and interpret the readings and, ideally, a schematic. At the very least a close-up, high resolution, in-focus picture of the innards might get you some more detailed responses.
