Your LCD TV uses backlights and they can be slightly visible when viewing a letterbox movie. However, if the light is really bleeding into the black, there could be a problem, but mosty this is common.

Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your tv power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement. Hope this will help...

The symptom you describe is consistent with an overload(short) on one of the power supply output voltages.
If you hear a clicking noise,that is one of the relays ,showing that the TV power supply try to start normally,but then a short condition is detected and power supply shuts off,and all repeats again.
Now from my experience with these units,the most common cause is the power board itself or the Y sustain board.To make the exact determination,further diagnose inside of tv set is necessary(voltages and resistances readings)-a common occurance would be some defective-bulged top capacitors in this power supply you will have to replace the board.
Depending on the models,these boards cost about-$250 to $300 each.Add another $150 for labor and the repair cost will be around-$400-$450.

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.
