hi welcome to fixya
i want to clarify first the problem sir so as of now the problem with your tv won't power on then you are using again the old main board is that right ? when you use the new replacement main board the tv is functioning will the only problem is that the HDMI / DVI inputs doesn't work. and now you encountered power supply problem like won't start up or something that cut the supply in which the stand by indicator is turn off so as my idea it has a problem with the old board. but before you come up with the board making sure all the connectors coming from the power supply is properly connected to the main board as will as flexible and lvds cable for the T-con board is properly inserted.just let me know if is that what you are asking for so i can give you additional solution thanks for consulting the fixya.

Most likely the power supply capacitors are going bad.
Opening the TV and replacing any swollen caps may solve your issue.
Thanks

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

Bulb is burnt out replace as needed and clean inside of set of all dust.

You can follow these instructions to change the code of yours. Might work for you.

NOTE: You must change the transmitter's code before programming the transmitter to the motor head unit.
The following steps describe the process to change a Quantum™ and Classicdrive™ security code.
This process only works fro transmitters with a GREEN LED and a "U" in their model number, such as "02-3047 2B U" or "02-3047 2B UH".
Changing the Transmitter Code
1. Press and hold the button on the transmitter that you want to change. The GREEN LED will flash once and then turn off.
2. Continue to hold the button until the GREEN LED begins to flash (approx. 10 seconds).
3. When the GREEN LED flashes, immediately release the button and then immediately press and hold the same button again. The GREEN LED will now come on steady.
4. Continue to hold the button until the GREEN LED begins to flash (approx. 5 seconds).
5. When the GREEN LED flashes, immediately release the button.
6. The code for this button has now been changed to a new randomly generated code. Do not push the button again until instructed in "Programming Transmitter to Power Head Unit".
7. You must now re-program this transmitter to the motor head unit. See "Programming Transmitter to Power Head Unit".
Programming Transmitter to Power Head Unit
1. Press the PROGRAM button located on the garage door motor head unit once. The PROGRAM STATUS light on the motor head unit will turn on and remain lit for one minute, indicating that it is ready to learn the Transmitter code.
2. Press the same button on transmitter as you did in "Changing Transmitter's Code" above. The PROGRAM STATUS light will turn off indicating a successful learn.
3. Press the same button on the Transmitter once more to operate the door.
4. If you are unsuccessful in programming the transmitter to the motor head unit of if the button does not operate the door or if you wish to program another button to operate a different door, you must change the transmitter's code.
Battery
If the LED does not turn on when button is pressed, replace battery.

It may very well be a connection issue with one of the wire connections as its not giving you a error code. I would double check the wire plug connections
