Question about Samsung LE40R72BDX 40 in. HD-Ready LCD Television

Open Question

I have a TV LE40R72B and an IPTV system connected via HDMI working ok for a year. Suddenly the screen turned blue with a message indicating inability to HDCP. Swap cables, equipment, ..., did not solved, it was concluded that this is a TV's problem. Connecting by SCART works ok. According to posts in different blogs, seems to be a recurring problem in Samsung, which there seems no solution.

SOURCE: samsung lcd ln46a550pf3 no sound from hdtv reciever

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

SOURCE: HDMI Cable problem

Well, first you might want to try another hdmi connection behind your TV.If it appears to have the same message,you need to check your TV setup and be sure the HDMI video is active.
Secondly,go with the recommendation of the set top box.You will use component video cable to connect from your set top box component video output(Y PR PB) to your TV (Y PR PB) and see if that actually work.If so,just use the cable box for the time being and call your cable company for another cable box to replace this one!

I'm sorry for the difficulties you're experiencing as the HDMI port on the TV is not working as expected. Please follow the below troubleshooting steps and check the operation.

  • Please make sure that the connections are secure and proper.
  • Unplug the TV from wall outlet for more than 5 minutes to perform a power resetting and check the operation.
  • Check whether the HDMI input is skipped.
  • Please connect a different device to the same port on the TV and check the operation.

Thanks for understanding. Please let me know the result after performing the steps.

LG blue ray won't play sound from RCA sound bar. HDMI cable is hooked into HDMi slot on TV


the details you provided were very vague, however from my experience when a device is connected to another device via and audio capable hdmi cable, that device renders it audio output to the device its connected to and normally turn off all other audio outputs beside optical- I would assume there is an option in the blue ray player to turn off hdmi audio, which will in turn activate other audio outputs- you may also look for audio out port on your tv, it is ideal to connect the sound bar directly to the tv set audio out ports. To sum this up,
if you plan to use your player via hdmi cable you need to turn off hdmi audio output on the blue ray player and the plug an audio cable from your blue-ray player to your sound bar
you may also as i said connect your sound bar directly to your tv, the issue is most tv sets now a days do not have an audio out port, if you do then everything you play thru your tv will have audio via sound bar
there are several way to go here but unless your sound bar has hdmi av switching capabilities (im sure not) this is one of the most simple--Good Luck.

You either lost HDMI on the TV or the Laptop. The way to tell is hook up the laptop to another set aand see if it works. If it does than the problem is in the Main PCB of your TV.

JVC LT-32DS75SJ issue with HDMI


Try this

1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.

Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

Monitor goes black - green light stays on


My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.
