Question about Samsung HT-Q70 Home Theater System System

2 Answers

Display and sound

The problem with my HT-Q70 is that every light on the display is lit up. There is no way to tell what functions are being switched , or what disc is playing. The volume control also does not go up and down.

    System was working, fine (except that the volume controller was wacky sometimes working other time up was down??) Then one day all lights on display are lit, no volume control. System does play sound but hard to figure out which device as no display. Also volume does NOT work. Any suggetions?

    I have the same problem. All icons are brightly lit. Luckily I can control the volume via the remote control.

    My Samsung HT-Q70 system is about a year and a half old . . . I was in the middle of watching a DVD and suddenly the screen froze and the front display went black. I turned off and unpluged then repluged and nothing, unplugged again and left alone for about 12 hours to ensure all memory was drained, etc. plugged it back in and turned on, now I had every led light on the front display lite and a clicking sound came from the unit. Unplugged again and let sit for some time, replugged it in and I still get the entire display lit but no clicking and no response from the unit.

    Having the same problem.. every light on the display is lit up. There is no way to tell what functions are being used. Cant change volume on front panel we have to use remote. Unit is only one year old... so sad.

    When my Samsung HT-Q70 was just 6 months old, the display began acting up. Partial letters, no letters, no way to tell what the heck was going on. I tried emailing Samsung who advised me to pack up the whole system and send it in. I'm too lazy. So I lived with it for 7 more months. Tonight every single light on the display is lit up and the system keeps shutting down. After fiddling with it for a while, I got it to stay on long enough to get my dvds out, but now what? I have to get a whole new system? Very disappointed in Samsung. I paid close to $300 for this.

    Well I'm in the same boat as the rest of you and that sucks! there is obviously a problem with this and Samsung should take care of these issues. Also my fan is often excessively noisy, and doesn't always work upon powering up.

    Other than that, I love the rest of my home theater set-up and Samsung Plasma.

    Same problem with my HT-Q70 - all the lights on display light up and you can't tell what is going on with the machine. Tried same thing, unplugging, but no luck. Anyone have any luck contacting Samsung for resolution?

    Purchased my HT-Q70 12/27/2006. Fan went out and was repaired under warranty. About 2 months, I put in a HD-DVD and all the lights came on and stayed on. Samsung said since unit was out of warranty, I could send it in along with a check for $160 and they would fix it. Fortunately, all systems work OK except there is no display. They did not volunteer any other type of fix. Needless to say: 1. no more Samsung products in my future 2. my new Blu-Ray will not be a Samsung.

    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.

Sounds like the microprocessor is toast. That isn't repairable.

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.

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

Display lights are all up and it shuts down in 3-5 secs (HT-Q70)


There is nothing you can do to fix that, unless you're a technician.
You probably have a partially burnt power supply. That is where the fuse but not busted. Could be blown capacitor which is common to china made SMPS power supply used widely on dvd players.

Have a technician repair it.

Good Luck

  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.
