It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Go into menu settings of tv and look to see if the energy saving box is ticked.this is usually designed to run by selection of user not by default from factory.you may even have an intelligent saver which can detect if the screen is using a lot of power when the image is predominantly white as opposed to black so it turns the brightness down.too clever for its own good!

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.
Hi Roy, I can not find the service manual for this TV,
Is it an overhead TV? if so, it would seem that it is out of alignment of the LCD cells
Try disconnecting all the TV's devices and see if the same happens when you put the menu?
It does not seem, a problem of interference, so it is observed in the photo
I await your comment

Hola Roy ,no encuentro el manual de servicio de este televisor,
Es un TV retroproyector? si es as?, parecer?a que esta fuera de alineaci?n de las celdas LCD
Probo desconectar, todos los aparatos del televisor y ver si ocurre lo mismo cuando pone el men??
