SOURCE: Sharp Aquos turns itself off
How many times per second does the POWER led blink? (dont worry about the OPC).
1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board
You can buy the parts online and fix if yourself!!

I had the same problem on my 37" Aquos. Sound went out about 8 months ago after 4 years. Technician said it was the Sound Power Supply. Total cost to fix was $440. $250 for the power supply and $170 for labor. Has worked fine ever since. When I asked for the old power supply he said he had to give it back as a trade in. I don't believe that so I don't really know if the power supply was the real cause.
Now I've lost sound on 4 channels on my 20" Aquos. Great picture, but wouldn't buy another Sharp product.

I called Sharp and told them about our problem. At first they denied even knowing about this kind of problem but after some back and forth, they finally gave me a case number and told me to call back on Monday (this was on a Saturday). I did that and at first they didn't want to admit anything there either but again, after some back and forth, they agreed to have the set fixed by a local company (under contract with them I suppose). When the people called to tell us when they were coming we told them that they had told us that they would be there a few days later and the service people said 'yeah, but we got the part in sooner'. So what does that tell you? They do KNOW about this problem - it's just getting them to admit it. The service guy brought some new boards out but they didn't fit so they had to take the set in while they ordered new boards. That took almost 2 weeks but we've got it back now and haven't had any more problems with it. Our set was over 2 years old but I didn't know it at the time - I thought it was just over 1 year old. But we did give them the model and serial number and am happy with the way things turned out. We live in Texas so I don't know how anybody else's problems were handled.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
