i noticed recently when i turn off my t.v. the timer indicator light goes on and blinks for about a minute then turns off.. it does this every 30 minutes after the tv has been shut off. could this mean the t.v is not recieving sufficient ventilation in the back ? the tv does turn back on with no issues.

Also, after first initial shutdown of the t.v. the lamp light goes on aswell, could this just mean it is cooling down..

anyone have any ideas what this could mean? sorry for the bump.
