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?

Customer: replied 1 year ago.

OK, it is Sony TV, can you recheck model number which seems incorrect?

It could be KDL-37L4000 or some thing.

Customer: replied 1 year ago.
That is correct

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?

Customer: replied 1 year ago.
we've tried that

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..

If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...
I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.
