If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV. I will forward a link to a page where you can get more information and troubleshooting steps for this issue. http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=C399467 Please perform the steps provided on the page.

This issue is related to a power problem in as much as the TV turns off on it's own. I think the TV has developed a power problem.
The problem is consistent with overheating on the power supply board of the TV.
The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.
When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.
This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
This is a common problem faced by many other users too. To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply board.
Sony specifically uses GM1 Board. In other words, Sony power supply board is called "GM1 board"
It's a bit technical job but yes its not at all a costly repair to do or get it done by the technician.
You can buy this part at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor (capacitors) most likely the normal operation will be restored. Or you can buy a refurbished complete GM1 power board from shopjimmy.com to save you some stress.
If this task is too technical for you, you can call a family or friend who has the ability to assist you (two heads are better than one).

7-blinks of standby light to Sony LCD TVs, indicates a fault to its power supply board. An over-voltage shut down. If you wish to get more details about this, check this link.
