First, unplug the tv set for 30 seconds, plug back in and try ti turn on.. Second, If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV not to turn on. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

Try to remove the vertical IC sometimes it become Shorted causing the B+ to drop. after removing try to switch on back check the B+ if ok and the LED not blinking then change the vertical IC.

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

SONY KV-25X5U, TURNS IT'S SELF OFF AND STAND -BY LIGHT FLASH'S?

The standby light should be flashing in a repeated count with a short pause between the counts. If you could post that count here, it will give us an indication of the circuit in which a problem was found and allow us to provide solutions.

Thanks,
Dan

TV Sony KV-29F1E turn-on failure, red standby LED flashes (starts after 10-20 attempts)

When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.
