Toshiba DVD SD-740. After inserting a DVD, the digital display searches and eventually reads "Error". Tried several DVDs with same result. Unplugged DVD player and pugged it back in with same result. Owner manual does not have anything in Troubleshooting on this issue. What should I do?

I have had identical problems to those noted above and to my utter amazement they have been solved by forcefully tapping the bottom of the player. It still sticks often so I guess I shall soon have to buy a new machine - not from Toshiba?

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!

The unit can recognize that a disc has been loaded but can not read the contents. This can be as simple as a dirty lens or more drastic like failing optics. Try cleaning the lens using a cotton swab and alcohol. If that fails to correct the problem and a music CD will play OK, then the optics are failing. DVDs require more laser power to read than a music CD.

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.]]
