What you should try is unplugging the tv, then push the power button. After about 10-20 seconds plug the tv back in. The tv should work now and if not, let me know and I can help you further.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Pressed power, heard the unit turn on, heard the tv show sound for a moment then it went into standby mode and the red light flashes six times, then pauses, six times then pauses, over and over and over. ...


Either your power supply is bad and needs replaced, or their is other circuitry issues. Bets to have a trained technician look at this and give you a quote for repair, it might be cheaper in the long run to replace the set.

TV went off, standby timer light flashing


Try unpluging from the wall and theplug back in and try turning back on to reset. Sometimes holding the power button in while pluging back in will reset it, every brand is different for the hard reset.

Sony Trinitron Wega Standby blinks & the TV won't turn on


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

How to turn standby off


The TV circuit may have detected a problem within its parts. You may have to check some leaking capacitors in the board or loose solders or burned components just to make sure. Normally leaving the TV unplugged overnight should reset it.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

No Power


The first thing to check is the horizontal output transistor,it might have shorted out and opened the fuse or safety resistor that gives him power to operate,sometimes it goes bad by itself and sometimes the output transformer goes bad and takes him out too.If you are familiar with tv service you have a place to check but if you are not to familiar be safe and seek the help of a servicer.Let Us know how it goes or if you need more information.
