Toshiba SD-K740SU player won't play dvd

SOURCE: need to make my dvd player multi region

This is not a Toshiba problem.

Most DVD players have region codes. If you play a DVD from your region 5 times, it will permantly set the code.

Blame the movie and record companies.

Even most computer DVD drives have region codes.

It's unlikely the sales person was educated enough in this topic to even know what a region code is.

Here's something else to consider. If the DVD you want to view is from England, they use PAL not NTSC, so it's unlikely you could view it on your TV anyway.

Get your son to copy the file from the DVD onto a USB FlashRAM drive, then mail it to you. They don't have region codes. Now you can view it on your computer, and make your own North American region DVD. Also, you could always have him e-mail the video to you, then burn it yourself.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Having the same problem. DVD player loads enough to identify it is a DVD or a CD, but won't actually start playing anything.

HI,

see if the player tries to read the disc. Load a disc and listen.
Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.


It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track.see if the player tries to read the disc. Load a disc and listen.
