It would seem that I have the same problem as others with the blinking power light. A crackling sound can be heard through the speakers. Before it totally cr*ped out lines appeared through the screen. After a restart it seemed to work fine for about 45 min, then the lines reappeared & grew till the screen went blank. Assuming it is the power supply issue. Can you get the your charges to refurbish & an address to ship to. Please indicate payment options also. Thanks

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given.
This series of TVs has a famous issue with the power board (part number MLT166A or similar). Several capacitors and zener diodes burn out causing some resistors to burn as well. If you are capable of doing component level repairs check capacitors on the board and zeners Z2, Z3, Z4, Z5 and resistors around them. If you prefer to spend hundred bucks and simply buy the working power board for it - ebay is your answer.
The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply. I service these power supplies, for more info write to email@example.com
I have a different thread going, but saw yours and had a question. Is your light blinking steady and then off? or is it a blinking erraticly or even flickering? My bad caps (15 of them) were all on the secondary side of the PSU. I have been told (thanks to Jaimie Hernandez) if you have a steady blinking, then it is very likely that you have a bad zener diode Z3(27v/1Watt) shorted in the primary side of the power board. If that diode is shorted, it's very likely that 2 10 ohms resistors might be open, these resistors are connected to the cathode of Z3. Also check for bad caps on the Primary side.
I had a huge incentive to fix the TV, it is my wife's TV and she has been in my Man Cave since it died. How about that incentive.
