When playing a DVD on my Samsung HT-WX70 the picture goes black from time to time (very ignoring) and every once in a while it will turn gray but the sound never misses a beat.

Over heating.

Hi!

Follow this:
1. Open tray and remove any disks in tray.
2. Close tray.
3. Switch Off Player and unplug from power. wait 30 seconds (this clears RAM)
4. Reconnect to power.
5. Turn on player with remote.
6. Press ENTER (middle button of the arrow keys) on remote. (ignore message on screen)
7. Press 8, 4, 2, 6, 9 using keys on remote.
8. Press ENTER on remote.
9. Wait until player finishes processing. (approx 15 seconds)
10. Player will turn itself off, otherwise turn off player with remote.
11. Turn power back on with remote.

Player is now Region Free.

Can you see or hear if the fan is running? Is there sufficient clearance (4 inches) between it and the nearest surface for airflow? Is it clogged up with dust bunnies? You may be able to fix it yourself.

Unplug the unit. Look inside the vent at the rear. Reach in with a non-conductive probe to see if the fan turns freely. If not, it's bound up and needs replacement or unclogging.

If it turns freely with power off but doesn't rotate with power on, it's dead.

If it turns sufficiently fast with power on and you still have Fan Check, it's a sensor.

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

I would be checking and trying new leads from the antenna part of your telly to where they go into the wall , we had a problem with a new tv that used to turn itself off and on we got the tv replaced with another new one and it still did it . it turned out to be a faulty cable from the pay tv box on top of the telly as they emit FM waves just like the radio and it was sending signals to the remote on the tv to turn it off

According to the instruction manual you turn off the unit and press the Stop button on main unit for at least 5 seconds. Didn't help me with my problem (shutting down for no apparent reason) maybe it will help you with your problem.

Hi,
Sure for helping,
If there is a power problem means it will not turn on man,
so kindly check with the power cable, there might be problem with the power cable thats why it is switch on and there after it switch off,
so to resolve your issue you please change the power cable and if you find still problem you please contact once again i will give you the final solution for that ok.

genarally tv output contain two signals.(steereo).it dosent have surrund output.thats y its not hearing surround sound from your system.

switch from 1080i to either 420p or 720p (720p is actually better)
there is also a downloadable program from samsung.com
search for ht-x40 downloads
8. home theater HT-X40T/XAA Firmware
this will upgrade the dvd player
