Question about Toshiba Televison & Video
The most common reason for a TV to display a blue screen with no picture is because the source device has not been set to the proper mode.
If you are using a cable or satellite set-top box, ensure that it is turned on and set to an active station. If the set-top box is connected to the television using a coaxial cable, then the television should be set to Channel 3 or 4 to receive the signal.
If you are using a VCR that is turned on, but not playing a tape and not tuned to a receivable channel, then a blue screen will be displayed on the TV. To resolve this, turn off the VCR or tune it to a receivable channel. If a cable or satellite set-top box is connected to the VCR using a coaxial cable, then the VCR should normally be set to Channel 3 or 4 to receive the signal.

Hello, I can tell you from experience that this is an inverter issue. Both the master and the slave have several transformers and sometimes you can't tell if they are damaged or not. I would recommend testing the leads from the inverters to make sure which one of the two is the one causing the dim picture.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

Normally T-Con board have nothing to do with powering up of TV. It's only affecting image when TV is on. So we can discard T-Con as a suspect for now.
Remove "new" main board and install the old one. If TV powering up and back light comes on - you've purchased defective Main Board and you should return it for exchange or refund. It happens all the time, boards that they sell most of the time are refurbished and sometime nothing was done and they send defective board to the other customer by error.
In case that TV is not powering up even with the old main board - look for something that you have done during replacement (like forgotten or overlooked connection, broken/bended pins etc.).

Basically it is problem of LCD Panel (screen) however some times T-Con board replacement fixed the issue (T-Con board is part of lcd panel but some part shop sell it separately). Main board is not related with this kind of problem.
Required T-Con board is available in ShopJimmy.com (click the link to view available boards)
If T-Con board replacement does not solve half screen vertical lines problem then LCD Panel will be replaced and it would cost approx new tv price.
Hope this info will help.
