Hello divalisaf,

These are a few things I want you to check first.

1) Make sure the cable set top box is on and the cable is connected to the TV properly (This may seem simple but I have had to charge many people a $60.00 service fee plus a $70.00 travel fee just to turn on a cable set top box)

2) Make sure the TV is set to the proper input you are using (RF( F connector) , HDMI, Component video, and or Composite Video)

3) Make sure the TV is set to the proper channel (either channel 3 or channel 4 depending on your area) The cable set top box should be action as your tuner.

If all of these conditions are met, then we can begin troubleshooting.

First determine if the other inputs work (HDMI, Component video (RGB), Composite video (yellow), s-Video (6 pronged black cable).
If the inputs work then you possibly have a tuner problem
If the inputs don't work then then problem is likely in the video microprocessor.

If the problem is in the tuner or the connective circuitry then we will have to determine where to get a replacement tuner (or you can just use one of your other video inputs)

If the problem is in the video section (which includes the microprocessor) we are going to have to troubleshoot the video section which will involve you having a background in electronics, if not I would suggest having a qualified TV technician perform service on this TV.

I hope this helps,

Thank you,

Sceptre model # x240. No picture or sound suddenly but will play DVD fine. Tried disconnecting totally and rebooting cable box but no luck. You can see the channel info on screen also.


If the channel information changes when you change the channel number on the front of your cable box, it may be a cable problem, and they may have already corrected it.
if the cable box is connected to the round connector with threads on it the TV needs to be channel 3. then you can change channels with the cable box.
If the cable is not connected with that connector, (the one with the threads), you need to change the input of the TV to which ever method was used.
If all else fails, I think the TV will determine which hookup you have if you auto program.

I can be playing music through this, and suddenly, all sound cuts out. Sometimes, if I solo a channel, I can hear that channel.


We need more information about how you are using this... specifically what is it connected to and with what type cables... You MUST use balanced lines either XLR or TRS cables. You MUST power this from the same receptacle as amps or other connected equipment. Use of plain old guitar type cables as audio interconnects from the output of this is a big no-no.

When i play dvd i hear background music really clearly and voices are hardly audible - this happens on channel 5.1. if i swap to channel 2. i hear the filmmaker commentary! dvd was working fine until...


sounds like the speakers are out of order and/or maybe 1 or 2 not connected. use a AA battery and "pop" each speaker wire. it's low voltage and amperage so it won't damage your speakers. but the pop will allow you to know exactly what speaker you have and if it's connected. now make sure to put it in the correct spot. i would start with the center channel. sounds like this one's not connected.
please rate if this was helpful!

No sound from front left channel


Hi, here is a procedure to discover the source of the problem. No sound from the left front channel can have several sources other than the left front channel itself.
Let's assume, for just now, that the speaker is good and the cable to it is good.
Here is a testing sequence to follow:
1 If you have a CD player connected to it. Put a CD in and put it into play mode.
2 reverse the connectors from the CD player to the receiver. See if the sound moves to the left speaker and stops on the right speaker. Or if it plays fine.
3 If the sound reverses channels, That cable is bad. Replace it
4 If the sound is still not coming from the left channel. Check the connections and cables to the speaker. MAKE SURE THERE ARE NO STRANDS OF WIRE TOUCHING THE CHASSIS OR SHORTING TO THE OTHER SPEAKER WIRE.
5 If there were. Correct it. Shut down the receiver and then after a few minutes turn it back on.
6 If it still does not work. check to see if a tiny amount of sound is coming from the left speaker.
If so, turn the music up and see if it pops back on . If that is the case there is a failed resister on the circuit board that is arcing when you turn up the volume. That being the case, it is time to drop off the receiver to be repaired in the service center.
Hope this helps,
Best,
Mark

Suddenly cannot record DVD after years


Hi,

Apologies for the delay in response. Your concern was just brought to my attention.

To your recording, based on your second posting (and would appreciate corrective information where applicable), your system is:
  • Cable provider > Cable Decoder Box > Panasonic DMR-E75V > TV (equipment setup)
  • single coaxial cable > yellow, red & white > yellow, red & white (wiring setup).
With your indulgence, a couple clarifying questions:
  • to watch the Panasonic when you play DVDs, to what channel or source or setting must the TV be set to?
  • to record a TV program/channel, to what channel or source or setting must the Panasonic be set to?
  • what is the brand and model of your Cable Decoder Box?
Initially, pls try:
  • play any known good DVD disc/movie. power on the TV and set to watch said movie;
  • without changing anything on the TV, STOP the playing of the DVD;
  • try changing channel on your Cable Decoder Box's remote;
  • pls post back result(s); or
  • do the above steps again but before changing the channels on the decoder box's remote;
  • try changing/cycling through the different input/source of the Panasonic DVD;
  • again post back result(s).
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

No sound from CDJ-800 MK2


Are you getting error messages? Running in thru LINE? Is not on mute? The possiblity of both not playing would lead to process of elimination.

Keep me posted.
