Tv won't turn on. It blinks green then red.

Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?

My thoughts is that your High Voltage Divider has gone bad. Sony is a great server as they still continue to have parts for these TV's Be prepared for a fairly expensive repair.

Problem for Sony Grand WEGA KDF-55WF655. Hello,

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?

Green flashing is normal. Red flashes are error codes. Count the error flashes.

3x - Lamp cover position or cover detect switch bad.
4x - One or more fans failed RPM test
5x - Lamp power supply/ballast failure
6x - Thermal fuse failed (usually)

Sony KDF-46E2000 - Screen Goes Blank

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
