I came home from vacation to find my TV blinking a green power light and the TV will come on for literally 5 seconds then shuts off. I have unplugged and replugged, held the power button for 10 seconds and the light turns orange then it turns red. Is this TV ready for the trash or can it be saved? Help please, Thanks!

Hi, Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number... A1085447A* LAMP BLOCK ASSY XL-2200U It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.
Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.
This is a common problem with this kind of tv. When you give the unit power the green light will blink because it is telling you that the projection lights are warming up. Sometimes it will take up to a minute. When you hit the power button again after only 5 seconds it told the tv to power off. I hope this will help you out.
