Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

The red light should be blinking a code. For example it will blink 4 times pause then 4 times pause or 5times pause 5 times pause, whatever the error might be. Let me know what it is and then we can help more.

SOURCE: Standby LED blinks 4 times
4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.
Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

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. If the issue still persists then service of the TV is required.
