There are two ways of turning this tv off. A "Main Power" button directly on the TV which turns it completely off or using the "Standby" (a mode which turns the TV off, but will leave a red light at the bottom of the screen) mode which is activated when using the TV remote's Power button or to press the Standby button on the TV. The only way to turn on the TV with the remote is to leave it on Standby mode, and that has been fine for the long time I have owned this TV. But one night I used the remote to turn it off (putting it on standby mode) and quickly remembered something I wanted to record (with my DVR). When I used the remote to turn it back on it turned on normaly, but then quickly shut back down to Standby mode. I tried turning it back on using the remote, but the button was not doing anything. I tried pressing the Standby button on the TV but that didn't work either. I then pressed the Main Power button on the TV and the TV shut down normally. When I pressed the Main Power button again it seemed as if it were working normally but then it shut

Re: can't turn on
When you turn the MAIN off you are killing all power to the set---Some advice---If you Google the model number of this set with the word problem after it you should find what I have seen a lot in these sets: they develop bad solder connections on the power supply printed circuit board---usually the board is about 18 inches tall and 12 inches wide--A number of sites online offer to have you ship them the board and they will resolder it for you. I have repaired about 12 of these with this problem in the last 2 years---The board has to be removed(there are quite a few plugs that need to be labeled and removed and lots of screws that secure the board in place.)
Maybe not a job for a do it yourself person but the soldering (if it is your problem) will take about 45 minutes(including removal and installing board back).
Like most modern sets this set uses lead free solder and it is soldered(the boards) in a wave or one step process---over time from heat and expansion some connections may crack or even break loose----I would look at the POWER SUPPLY board(follow the power cord as it goes right to it)

The standby light on a Sony television indicates when the television is turned on and operating, or turned off and in "standby" mode. However, this light also serves a secondary function: indicating when there is a problem with the television by flashing. When the standby light begins to flash, there are two reset options that can be performed to resolve whatever issue it's indicating -- a power reset and a factory reset
1. Turn off your TV
2. Unplug the television from the electrical outlet. If you're using a surge protector or power strip, disconnect the television from the strip itself. Only by disconnecting the power cord from the outlet can you ensure no power reaches the TV during the power cycle.
3. Leave the television without power for at least 60 seconds. This gives the television enough time for all components to power down during the power cycle
4. Plug the television back into the electrical outlet. If you're using a surge protector or power strip, plug the television directly into the wall outlet instead. The surge protector may otherwise interfere with the power-up cycle, especially if it is old or damaged.
5. Turn on the television. If the blinking standby light continues, you'll need to move on to the factory reset process.
1. Turn on the television.
2. Press and hold either the "Reset" or up arrow button on the remote control.
3. Press and release the "Power" button on the front of the television, while keeping the "Reset" or up arrow button on the remote depressed.
4. Release the "Reset" or up arrow button.
5. Allow the television to reset after the "Reset" message appears on the screen.
6. Make no adjustments to the television for at least one minute after the reset has completed. This is to allow the television time to finish auto-configuration and initial set up.
7.Turn off the television and unplug the power cord from the electrical outlet.
8. Wait ten seconds, then plug the television back into the electrical outlet and turn on the TV.
9. Follow all on-screen instructions to complete setup. These are the instructions displayed the first time you set up the television, for configuring channels, menu language, time, display properties and more.
Check your TV's remote battries. If they are good, then, power off the TV at the main wall socket and unplug the power cord, leave it for 5 minutes. Now, connect back the main power cord, hold the Power On/Standby button on your TV and power then turn ON main switch on the wall. This should resolve your issue.
There seem to be a problem that is why the television is not coming up and stays stuck on standby mode.
First try to turn on the television using the remote of the television and ensure that the battery of the remote is properly working, you can as well try to push the channel button on the television if the remote does not work.
If it does not come up both by using the remote and pushing the channel button, then it means it is a hardware problem, and that is from inside the unit of the television. Since the standby light comes up, it simply means power is reaching the main panel of the television.
This mainly used to be caused by a faulty or bad capacitor on either the main panel or the power panel of the television.
The Standby LED blinks when the TV is turned on, then shuts off when the picture is displayed. If the LED blinks continuously, this may indicate that the TV requires service. Before getting the TV serviced, try power resetting the TV and factory resetting.
Try the below steps also:
Connect the TV to a different wall outlet and check if it helps. This is to check if the issue is with the Power.
Disconnect the TV from the Power Strip or the Surge Protector and connect it directly to the Wall outlet and check if it helps.
To Power Reset the TV, disconnect the Power cord for a short period of time (approximately 1 minute).
Then, reconnect the Power cord and power ON the TV.
To factory reset the TV, turn it ON. Then while holding down the RESET button on the Remote Control, press the Power button on the TV front panel.
The TV will turn OFF and then turn ON again. Then release the RESET button to complete the reset procedure.
If the issue persists, service may be required.
these particular tvs are very sensitive to voltage changes spikes etc.first turn off main power switch wait at least 30 sec if standby come on wait another 30 then turn off main power again and unplug tv for 1 min then plug in turn on main switch wait 30 sec then turn on tv with remote resets system.then buy a ups and always wait at least 30 min after turning tv off to turn back on if not causes power failure and after each press of power button wait 30 seconds before trying again lmk good luck
What did you try so far? The main power supply MUST have at least the 5V standby supply section working. This 5v is used by the main control board to send out the command to turn on the main power supply section which will power up the rest of the TV circuits when the power switch is activated either by the power button of remote or on the TV powern button. Look for this 5v first.
I have the same problem, my Bush LCD worked fine last night but won't turn on today. The main power button on the TV puts it onto standby but the remote or the buttons on the side won't turn it on!....HELP!
The amount of standyby power consumtion is minimal. The only way to turn it off completly is to disconnect the power from the TV. This will however increase your start up time when you want to use the TV.
