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.).
Good luck!

SOURCE: Viewsonic N2635W. Did not turned on. I replaced

You should also replace the cable that connects the main board with the control button.
Also replace the control button main board(a motherboard with all the buttons)
For example look here. It should look like this

finally replace the ribbon that connects it to the main =board since these are the only important things that could still cause the problem you have.

Please rate if this helped you.

SOURCE: My Vizio 55XVT1A power on, has sound, but no picture. I changed new power board, main board, T-cond board, but it still same problem. What's wrong with it? Is it anything with inverter board? Than

If this is an LCD tv the backlight inverter is bad, a good way to check it is to shine a flashlight close to the screen and see if you can see a faint picture.
Let me know what you find

SOURCE: sharp Lc-26sb24u white screen with sound

You will get a white screen when you unplug the t-con from the main board. Doing so removes power to the LCD panel. Verify that all of your voltages from the power supply are correct. If they are, I'd look at the t-con board. It sounds like there is a problem with the t-con that is pulling down the main board.

The answer to my question was to replace the T-Con Board. Looking at Shop Jimmy the only board for this model is BN44-00801E Power Supply/LED Driver Board. Is the T-Con board embedded in this board?

The T-Con board is embedded in the main board and not in the power supply/LED Driver board.
The Main board part number should be BN94-09124C but I would suggest to do more research or call Samsung for more info.

Lg 42" tv not displaying screen image

The t-con board controls the picture. To test it shine a flash light on the screen abd see if you can see an image when the TV is on. If you do then the T-con board is OK. Look at the back light ballast board (sometimes is part of the power supply board) If you see no movement or a dim picture with the flash light, then the T-con board is gone.

Jimmy shop.ccom has T-con board part #T500HVD0.0 500t10-C02 at the bottom in the description it list model PLDED5030A CRk my model is PLDED5066A-E since the parts # the same will it work in my tv?

If you see an image with a flashlight the T con board and power supply board are good. The back light controller board is the culprit.

LCD TV diplays blue screen on all inputs

Nothing on all inputs would suggest the Main AV board not processing signals, if all other functions such as volume, menu access, on and off operate normally the power supply board is probably functioning OK. Have a look at shop jimmy for an idea on price and availability for Mitsubishi LT-46144 Boards and spare parts:

I have sony bravia kvl40u100 it has sound no picture what could be wrong

If there is white light coming out of the back of the set, it sounds like the inverters are firing and your backlights are working. Is the screen pitch black? Gray? White? Blue? It could be a defective T-Con, main board, faulty power supply rail, or in rare cases, a faulty LCD panel.
