Since this is affecting several functions, the problem is likely the main power supply.
It may be that the supply itself is failing (switched mode power supplies like hari-kari) or an assembly (possibly the backlight invertor) is producing a fault condition which is causing the supply to drop out to protect itself.
Try the instructions below -
The supply is normally built on a separate board since these are often out-sourced by set manufacturers.
Unplug your set overnight to allow potentially hazardous voltages to discharge, remove the back panel of the set so you can see the guts.
Look for a smaller board with larger parts on it; some cylindrical (capacitors), others block-like and relatively large (chokes and transformers).
You should also see a relationship between the board and the incoming AC.
Check the board for a label or if not present, a stamped-on number.
Call the manufacturer's service center with your TV model number and the number found on that board and inquire about repair/replacement costs; if both are offered, they won't be that much different.
If you must buy a new board, don't dispose of the failed one as there are smaller companies that can repair it for less than the mfr. and then keep it as a spare as this problem will likely arise again.

When the TV is on, need to check the back light is on(go back side & look into through)
If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)

You got sound meaning the power supply and mainboard have no problem at all. Look at the back, have you seen back light lit up?
If there is light, the problem may come from T-con board.
If there is no light so the inverter board has defective.
