Hello XXXXXXXXXX,
Thank you for asking your question on Just Answer. This problem is caused by a protective circuit in the TV detecting a problem in the circuitry. It will turn the power to the TV off automatically to keep further damage from occurring. Turning the power to the TV off will reset the TV back to factory settings. This is allowing the TV to operate until it detects a problem again. Most likely some of the electronics have changed value. The resistors can burn and the capacitors will leak. This will cause other parts to heat up and become defective. This is not normally a DIY project since special test equipment and training it needed for TV repair.
You might be lucky and resetting the TV could solve the problem . To reset the TV, unplug the TV and leave it off for an hour or more and plug it back in. It may start working if not repair is the only option.

Hopefully your TV will still be covered under warranty. If out of warranty the price can vary depending on who is repairing the TV and their labor rates. I would not be surprised it the repair is not in the $400 ballpark for parts and labor. Many customers opt out on having the TV sets repaired, due to the cost and the fact that the set will not be covered under warranty and other parts can fail at any time. The sets are coming down in price. I feel that Sony should offer to help pay for the repair cost since it is a common problem but most of the tome Sony will only state it is out of warranty and the repair cost is up to the customer to pay for. I wish I could tell you there was a button that you could push to make your TV operate correctly.
Yes, parts can be ordered on line, from Sony and from most electronic repair houses. The problem is determining what parts are defective. Many times one part will cause another part to fail. This can cause another to fail. This can continue down the line. Special test equipment is needed to check the specks on all the parts in the circuit that is having the problems, which again can be caused by other circuits. This test equipment is very expensive and can require training to use it. Many of the newer electronics use surface mount and soldering these boards requires great skill and the proper equipment. Replacing parts that are not known to be defective can get very expensive fast and then there is always the possibility of the new part being damaged by a defective part that was not replaced. This is why I would suggest that TV repair is not a DIY project for most consumers.
