Dm800HD no boot, no display, only LAN leds blinking

[cristi_drag]

Hi. I have a problem using a clone DM800HD. I have changed some time ago the satellite tuner with a DVB-T one. After a time, having problems with the power cord and with plugs something happened so that I have heard something like an explosion but without noticing smoke or something else. After that any try to reuse the box was unsuccessfully. First of all I have no display, no power led status, no boot using dream up or anything. The only thing that makes me hope is that I still have the LAN led from the back of the box lighting. I have checked with other power switch, I tried extract the SIM and to reput him back cleaned. I even extracted the display and/or tuner hoping that I can reboot or revive the box. Endly I have extracted the whole motherboard to check if I can see some capacitor broken or even a sign of black trace further the explosion. Nothing. Can anyone help me? What other option can I have? Is there any? Thank you in advance.

Take a look for swollen caps, unless your a electronics guru it about all you can do there are some surface mount fuses on the underneath of the board but i struggling to find the diagram, if i find it ill post it, the Ethernet lite always seem to work even when the power side has gone down.
