If your remote isn't working, first ensure there are no obstacles between the remote and the player. Also, make sure you're not too far from the player and that you're pointing the remote directly at the remote sensor on the player. Finally, check if the batteries in the remote are weak and replace them if necessary.
Why is there no sound coming from my Sony RMT-D157P DVD Player?
Several factors can cause a lack of sound. Check that the connecting cord is securely re-connected. The player might be connected to the wrong input jack on the amplifier (receiver), or the amplifier input might not be correctly set. Also, the player may be in pause mode, Slow-motion Play mode, fast forward, or fast reverse mode. If using DIGITAL OUT, check the audio settings. When playing a Super VCD, sound won't come out if audio track 2 isn't recorded and you select '2:STEREO,' '2:1/L,' or '2:2/R.'
What to do if my Sony RMT-D157P disc does not play?
If your disc isn't playing, make sure it's inserted correctly with the playback side facing down on the disc tray and that it is not skewed. The region code on the DVD must match the player. Also, the player cannot play a recorded disc that is not correctly finalized.
Why is the sound volume low on my Sony RMT-D157P?
The sound volume may be low on some DVDs. You can try setting 'AUDIO DRC' to 'TV MODE' to improve it. Also, make sure that 'AUDIO ATT' in 'AUDIO SETUP' is set to 'OFF'.
Why is there no picture/picture noise appears on my Sony RMT-D157P DVD Player?
There could be several reasons for the picture issues you're experiencing. The connecting cords might be damaged, so ensure they are securely re-connected. The disc itself may be dirty or flawed. If your player's video output runs through a VCR to your TV, or if you're using a combination TV/VIDEO player, the copy-protection signal on some DVDs might be affecting picture quality. Also, check if the player is set to progressive format while your TV doesn't support it; if the PROGRESSIVE indicator is lit, press the PROGRESSIVE button to turn it off.
Why is the sound noisy on my Sony RMT-D157P DVD Player?
When playing a CD with DTS sound tracks, noise may come from the LINE OUT L/R (AUDIO) jacks or DIGITAL OUT (OPTICAL or COAXIAL) jack.
Why does my Sony DVD Player start playing the disc automatically?
Your DVD player might be starting discs automatically because the disc itself features an auto playback function. Alternatively, check if 'AUTO PLAY' in 'CUSTOM SETUP' is set to 'ON'.
Why does my Sony RMT-D157P DVD Player stop playback automatically?
If you're playing discs with an auto pause signal, the player will stop playback at that signal.
Why won't my Sony RMT-D157P DVD Player play MP3 audio tracks?
The DATA CD may not be recorded in the MP3 format that conforms to ISO9660 Level 1/Level 2 or Joliet. The MP3 audio track may not have the extension '.MP3.' The data may not be formatted in MP3 even though it has the extension '.MP3.' The data may not be MPEG1 Audio Layer 3 data. The player cannot play audio tracks in MP3PRO format.
Why doesn't the disc start playing from the beginning on my Sony RMT-D157P?
The disc might not be starting from the beginning because Program Play, Shuffle Play, Repeat Play, or A-B Repeat Play has been selected. Also, Resume play may have taken effect.
