A toshiba SD-37VSR DVD player that the TV will not recognize

What happens when you press the "Subtitle" button on the DVD remote control several times after you insert a subtitle-enabled DVD?
If you don't have the manual handy for your DVD player, I've added a link for the Toshiba SD-5000KU. The Subtitle button is described on page 13, but the description only tells how to turn subtitles on. However if the programming is typical, pressing the button repeatedly cycles through a series of language options with "Off" at the beginning or end of the list. Otherwise, it may be programmed to enter a subtitle menu that you navigate with the direction arrows (page 14).

With most Toshibas, you could un-plug them and leave it for either 10minutes or 30minutes and it would reset. strange, I know. give it a try.

I also found this when working on a similar problem with your player, it may be relevant -you could try pressing the power button and another button..
sorry, I don't have one in front of me to test..

[[power off the player
hit the power button and immediately hold the HDMI select button
the 3 HD indicator lights will cycle and then pushing the HDMI select button will move through the resolutions.]]

I presume that you've selected the correct inputs on the TV? Go for HDMI if you have it on your TV. If not use the yellow (composite) and ensure you have nothing in the S-Video (Toshs don't like using composite and S-video at the same time).

it is 1110 the code for Toshiba SD-K510 it works on mine Toshiba SD-K510 the code on mine universal remote

Followed the manual to return to the Default settings, using the remote "in the blind" pressing the arrow and Enter buttons, hoping I hit the right menu button. I did. Case solved. Thanks

Greetings and Salutations,

If your using the component outputs from your DVD player I would first check to make sure that the cables for the Red and Blue channels are connected properly. If the cable is connected correctly then try replacing both the Red and Blue channel cable. If this fails to fix the problem try connecting to another component input on your TV if you have one available. 

You might also want to check to see if you switched on the progressive scan switch on the back of the VCR/DVD unit. If you know someone with another DVD player have them bring it over and see if the problem is still exists. 

If the green picture is still present then the problem is and internal problem with the TV and you will need to find a repair center for it. If the problem goes away then the problem is with the VCR/DVD combo unit. You can at this point also try using just the Video Out from the DVD player.

Hope these suggestions will help you with your problem.

Try this, as posted on www.videohelp.com:

Put in DVD.
When you get region whine message press: [menu] [1] [play]
Disc should play, but with region message still up.
Press Marker then Clear. Message is now gone.

You can go to the menu for setup, or keep watching the movie.

I had the same problem with the same player for some DVDs. Fortunately, for me, there is a solution that has worked 100% of the time.

I am assuming you are probably setting the DVD player to upconvert to 1080 i or p. What you need to do is go to DVD setup and change the resolution back to standard def (480i) just for the menus. The menus will now work properly. Once the movie starts you can switch it back to 1080i/p with no problem.

First thing before a landfill is to go into the units menu and see if something in the audio got turned off if not then inspect the connectors on the back for breakage. Good Luck
