SOURCE: display and sound

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.

SOURCE: SAMSUNG HT-TZ212 home cinema kit comes up with protect

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.
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.

Regards.

SOURCE: how do i connect/play my turntable?

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

Everytime I turn my on samsung ht-q70 the display screen says protection and the system shuts off. what can i do to get the protection off


The amplifier has a bad channel, or is bad itself. It is trying to either output too much current or is not putting out enough. If you have multiple speakers wired to one channel, you will either have to change the wiring to series(unit positive to first speaker red, first red to second BLACK, second red to unit negative) or remove on speaker. (If this is the case, then you might want to look at this. It is a tip/rick to place and properly/successfully run three subwoofers, but the main concept can be used on all channels.) If all channels are wired to he correct speaker, then the amp is in fact at fault.

Turned on system. it shut off. tried to turn it on again the display screen lit up and went out now i get nothing.


If every segment on the display lit up it will need a display driver IC (pain in the a## to replace need to remove the display to get at it) and it will also need a transistor in the power supply.

My Samsung HT-Q70 5 disc drawer won't stay closed. It doesn't matter if a disc is in or out or radio selected or anything, it just pops out. Anyone with an idea??


make sure its fully cleaned. many appliances will automaticly open the disktray if there is a reading error. DO NOT TOUCH THE LENS. i suggest a simple blow over the lens and cleaning the disk, try again. if all else fails, contact your seller and get a trade in.

I just want to know if I can connect my laptop to my Samsung HT-Q70 Home Theater System for audio so I can hear the sound from the laptop on my Home Theater speakers?


Yes you can and it is very simple. All you need is a special wire. One end fits to the earphone jack on the laptop, and the other end looks like rca cable. At the back of your home theater choose aux in, and connect the rca end of the cable to that. Then the other end looks like a headphone jack, and you connect that to the laptop headphone jack. Now on you home theater select aux. You will everything that comeout of that laptop including the windows vista melody when you first boot it up. Now you are ready to enjoy music.

  1. With the home theater system off, press and hold the REMAIN button on the home theater's remote control for 5 seconds.
    Note: You can release the REMAIN button when the POWER LED blinks blue/Red depending on model.
  2. With the SWA-3000 turned on, use a ball point pen to press the RESET button on the back of the SWA-3000. The POWER LED in the front of the home theater blinks two times.
