Noisy NS50P DVD audio output.

Use three RCA cables, yellow, white and red to connect DVD player to TV as shown in the diagram below. Connect yellow to yellow and white to white. Connect red to red. Select on the TV, the A/V input where the DVD is connected using the TV remote control. Power on TV and DVD, place a disc in tray of DVD player and press PLAY.

Connect yellow video output on DVD player to yellow video input on TV using RCA cable. Connect white audio output on DVD player to white audio input on TV next to yellow. Connect red audio output on DVD (next to white) to red audio input on TV using RCA cable. Select on the TV using remote, the proper input for DVD player connection.

Is the humming just from the power on or is it when the DVD is spinning some media will spin with a loud humming noise something to do with the balance similar to an unbalanced car wheel, just a lot quiter. Burn the DVD using ImageBurn create an ISO and reburn.

If it hums without the DVD spinning it is probably the transformer on the PSU on it way out this can happen at any time it is caused by the voltage step down coil becoming damaged in some way and the lower voltage provided causes the noise.

If this is the case I suggest a new PSU or at least a new Transformer.

your cables are not good audio rca cables....are faulty replace the rca cables...

the difference between tv and av, is that av has no showers on the screen. if you change to av you will notice a blue screen, connect your yellow on vedio output and white/ red on audio out of tv
note- before connecting to a vedio touch a tip of your vedio cable some lines will show on your screen, if touch your audio tip harming noise will sound on your tv. if this two happens then you know that your cables are okey. hold your channel button on your tv, channel will start runing after all rf channels finish, tv will go to av.

Swap out the red/whites - loud hum means something isn't hooked up right

Make sure a/v cables going OUT from dvp and IN to tv

PAL/NTSC is automatic. if you insert a PAL DVD output is PAL ( most probably PAL-B. Some other brands allow manual PAL/NTSC switching, but at this machine this is automaticaly done. Please verify your TV set allows PAL programs

You have to double check the inputs of the video in as well as the audio in on the TV set. they come from the video and audio output on the DVD player. Good Luck

Out put Capacitor breaking down - needs a serive replacement if available.
