Hi
3 Times Blinking is for the following reason
DC_ALERT -------> DC_ALERT
DTT_WDT --------> DTT Error
AUD_PROT -------> Audio Abnormal Detection
Kind regards.

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.

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

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.
