SOURCE: Hard time turning on tv. I turn it on, green light flashes a few times then becomes solid green. No picture or sound. I turn it off and light becomes red. I do this at least 5 times before tv will
There are some capacitors on the main boardthat are low quality. You can buy a capacitor repair kit on Ebay that contains a set of capacitors to replace the offending ones - about 15-16 bucks. I soldered in the new capacitors and the TV has worked perfectly since.

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

sound like you have some bad capacitors inside your tv take the back off and check them if capacitors are raised up on top they are bad
