The DVD player is region locked and will only play DVDs from a particular region. The cheap DVDs are probably region 0 and so will work on any DVD player. You can scour the internet for a code hack to change the region (I've had a quick look and not found anything).
If after trying the TV again later and problem persist, repairs are in order.
A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube.
Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry.
Good luck and kind regards.
The TV is in the DEMO mode. Many sets have a demo mode, and they are all turned on and off differently. I do not recall exactly how it is done on the Toshiba, but if you look in your owner's manual or go through all pages of the menu, you should be able to find the option for demo mode and be able to turn it off.
Hi Daren, it's a very strange fault, the one you mention
I sent you a link that talks about a similar failure on a Toshiba TV
I hope it will help you and you can solve the problem
But I suggest you look for a specialized technical service

If the current firmware in your blu-ray player supports multi region then try this.
1. Power on the blu-ray player.
2. Press "Setup" on the remote to enter Setup Menu.
3. Using the remote, enter "8520". A new submenu will appear.
4. Set DVD region code to "0" for DVD Multi Region.
5. Set BD region code as required using the remote buttons.
"1" = Region A, "2" = Region B, "4" = Region C
6. Press "Setup" button to exit the menu.
If this does not work then try upgrading the bluray firmware.
Search for Toshiba BDX2150 firmware and see if there is a newer firmware than the one you have installed.
