Blade7000 Faulty

hi i have had my blade7000hd for 2 years now and ever since its been great loved it  but unfortunately nowadays its been turning off completely at random times.. so never know how long it will last.. i have posted before about this issue.. i have tired to change the lnb on my motorised dish and also replaced the cable but am 100% its nothing to with that as i have tried my sly fix dish and still same problem.. when it goes off there is a random number on the front panel(seems like box I.P) and sometimes it will go off and have a flashing red light and not come on.. only soloution is that i need to turn box off for few mins and back on but this is extremely annoying as you can imagine.. I have been told that the tuner on the box has gone or finnished.. Can someone please help me with this issue,, and has anyone else had this issue before?
Cheers

Is the box well vented perhaps it's overheating.
When the box crashes have seen one digit from last channel watched.
Have you tried a factory reset, https://dooby2oons.forumotion.com/t2237-blade-7000-hd-3d-all-info
Remember to copy cline/channel list as all will be erazed

Yes mate iv tried a factory reset via the box.. via the boot engineers menu and via rs232 cable flash.. iv also tried all diffrent firmwares orignal and patched but no luck  what i have been told that the tuner has gone or finnished on the box

If the tuner had gone no channels would be working or pick-up on a scan, could be psu.
Disconnect and have a look inside for damaged parts eg caps, is the box warm when it goes off.
