Hello,
I'm having a problem with my DM7025. Don't know what happened, but suddenly, the hardware doesn't boot up any more.
when i turn on the unit from the back, the Front display is lighten up without any display.
TV display nothing but black for around 1 minute and suddenly it flash some white bars all over the TV screen with a Sound coming from the Receiver (Probably Power supply).

could anyone please help me investigate further this problem? is there any hardware diagram in which i can test if my PS is faulty? where to order to new PS if it was faulty - I'm in the Middle East BTW.

Thanks,
