When I turn on my tv the light goes to from red to yellow but the screen stays black for about a min then the red light comes back when you turn it on again it stays on longer but no screen when you unplug it and let it reset and then hit the button it starts right up and shows the blue proscan screen I have only had this tv a year!!!
This is a prime case of bad capacitors in power supply. You may have only had it a year but how old are the parts that are in it?

Yes, its most probably lamp issue.
Please but original Sony lamp from Sony store and replace it in TV.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also
ensure that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem with no receiver box
or dvd connected.
If that does not work, and you keep having a flashing
led on front of the TV, and tv turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults
that can occur are a blown capacitor on power board, a
convergence IC has blown, or a fault on Digital board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
