I had the same problem. My piece died after the 12 month warranty. But,
there was an additional 3-Month Warranty Extension if you Registered
the piece On-Line. I had done that. The Samsung Service Center said
they did not have access to be able confirm that I had registered it. I
had the date registered but that didn't matter to them. They just
wanted me to forward the Proof of Purchase info to them(which I Scanned
& E-mailed). Once they confirmed this. I shipped them the Main Unit
Only(not the Speakers), they repaired it, & returned it. The parts
they replaced on my piece were: AH92-02494A(Display Malfunction),
AH44-00112A(Dead Intermittently), AH64-03942B(Appearance Item Defect),
& AH31-00039B(Mech. Noise or Vibration). It's been about 1 year
since repair & so far works well.
When this piece failed I also smelled an electrical burning smell. It was very soon after I had touched the On/Off Button.
I BELIEVE THIS UNIT MUST BE GROUNDED, IT MAY BE VERY SUSCEPTIBLE TO STATIC DISCHARGE AND GENERATES IT'S OWN STATIC FIELD AND DOESN'T NEED MUCH TO COMPLETE A CIRCUIT. GROUND IT(and yourself) AND ONLY USE A REMOTE CONTROL TO OPERATE THE UNIT. BE CAREFUL WHEN INSTALLING MEDIA TO ENJOY. HOPE THIS HELPS SOMEONE. Can't say I won't use Samsung again because it's all garbage in, garbage out in this disposable society we've allowed ourselves to be a part of.

Protect mode will kicking whenever a fault is detected.
Causes that can start protect mode are:
Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.
Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

the fan is broken on your unit, this is a feature to keep the unit from over heating
check if there is anything blocking the fan from moving/rotating
try to contact your manufacturer

Hi sorry to say cant go direct.
What you can do if really want it running is get a RIAA pre amp with power supply (search google local shops). The turn table plugs into that, then that plugs into one of the analogue inputs of the Q70. That will work great if prepared for the effort!
Best of luck
