When I put in a DVD, the TV screen displays "Invalid region"

You can make the Player to play all-region DVDs [not Blu-ray discs]. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Procedure to make it region-free to many DVD brands are given.

This means that the region code on the disk (which determines where it may be played) does not match up with the region of your DVD drive.

Normally the region code can be changed, but only a limited number of times.

Try to make that if you buy a DVD online, it has the correct region code for your player

Could have still been hit by a surge. Take the back off of the TV and look at the main board were you connect your HDMI. See if it is scorched or components that blackened. Also check your DVD player on another set. Your DVD player could be the problem.

You can not fix this, DVDs are coded in such a way that a for instance a DVD sold in the European market can't be played on a DVD player sold in the USA. You can buy region free DVD players, but they are not sold at the local electronics stores, they are available on eBay I'm told.

how to make multi region of my dv-sp406

Region 1 is US/Canada. This is your only available region. If you put in a DVD from a different region, it will not work.

You can make this player REGION FREE so all discs operate on it.

Power up, no disk in. Status says READ then INSERT DISC.
Press MENU (status reads invalid key icon)
Press 1 (status reads invalid key icon)
Press 9 Menu is displayed.
Press ENTER on the region, digit turns to "-"
Press 0
Press ENTER again
Press EJECT to clear the special menu.

If you reset (unplug) the player for any reason - this will need to be re-entered.

Thanks for using FixYa!!

If you go into your factory settings setup screen check there for what region its set to and if it is possible to change it, change to the correct one.

First thing to do here is to check the connection adn if possible try a different cable , because sometimes this can only be a connection or a cable problem,, as for making it unlock so you can watch any DVD on it, there's a lot of site there that is offering that service to unlock the regional code of this unit...

Hope that helps.........

PS If you're gagging to get at this and the remote doesn't work, pull out the tab that isolates the supplied button cell in the remote control :-)
