Hello and Welcome. My name is ***** ***** I'll assist you today. I'm reviewing your question now, and will post back with your reply ASAP.
- Could you please get me the model number written on unit in question?
OK, it is Sony TV, can you recheck model number which seems incorrect?
It could be KDL-37L4000 or some thing.
OK, so TV model number is *****
Have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and check?
OK, 4 times flashing power light indicates problem with main board of TV and replacement of main board will resolve the problem. Since TV is approx 8 years old (2008 model) so it would be tough to get replacement main board, however, check with following board supplier to see if they can get it for you..
