The standby indicator is flashing 4 times on my sony bravia KDL55nx720 tv and will not start. Is there something that needs to be reset?

It will come on for about 10 seconds than it stops and the standby indicator flashes in red four times every three seconds.

SOURCE: Four blinking red lights.

you can have the inverter board replaced...instead of the entire panel.
KDL 40S2010: inverter part # 178950032, you will also need 2 spacers..part # 289765511
you're looking @ 200-300$ for the inverter and 5-10$ a piece for the spacers.

KDL-46V2500: inverter part # A1251295B
you're looking @ around 500-600 $ for the part

SOURCE: sony bravia-flashing red light

I would guess your power supply board is slowly disintegrating. It is hard to tell what it is, until it finishes frying itself out. Plan on replacing the power board soon, 1-3 months maybe.

When turning on tv. screen will display Bravia image & then go blank. red light flashes SIX times

Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TVicon1.png will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.

Two blinks indicates 'Over voltage protection'. Check its main power regulator board. In most cases, it might need replacement. To know more abut the blinking codes to Sony TVs check this link.

Sony bravia KDF-50E2010 RED LIGHT FLASHES 4 TIMES THEN 3

Sony TV LED & Blinking Codes - What Does It Mean When Standby/Timer Light Flashes Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue.
when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself.

My Sony Bravia KDL 32S2030 is showing a flashing led standby (4 flashes/2 secs/4 flashes. I can unplug the mains cable, leave it for a few minutes and when I pug it back in it will re-set to the green...

I'm not a service tech, but, I do have a copy of the service manual. It says the TV has a self diagnostics and according to the chart, 4 flashes indicates a backlight failure.

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.
