Question about Televison & Video
I am having the same issue that you had with your tv, and was wondering if you got yours fixed? If so what did you do? My email is email@example.com
You need to change your TV's settings and enhancements. Directly from the store and out of the box, the settings are adjusted for easiest sell in the store. That means that:
Your contrast is cranked to 100. Move this down to 50 to 60.
Your brightness may also be cranked up high. Lower it to a level nearer the middle range but not so dark as to lose detail in the shadows.
Your TV is set on "Dynamic" or "Vivid" mode. Pick "natural" or "normal" or standard.
Your sharpness is at least on, if not cranked up. Turn sharpness down or off, and the same with "Edge Enhancement" and "VSM", all to off.
Lastly, I bet you upgraded size and you are now sitting too close to the TV. Roughly, if you are sitting closer than 130 inches (about 11 foot) you might do some rearranging or save some money and get a smaller TV.

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.

Do you get any indicator lights at all, if you do, then the 5v standby circuit is working, if you get nothing at all, then the main power supply will be the first palce to look, blown fuse? capacitors?

I had a similar problem. I had a 52"
RCArear projection tv. It
would do this when I initially turned on the television, but then after a few
"on/off, on/off, on/off" cycles it would stay on. Eventually it
started doing it more; until finally there was a spark and that was it. The tv
was dead.The bloggers called it "the blinking green light of death" (because
of green light on the panel).The
power board is going out.ALSO holding down the Input and Menu buttons afterward will give you
some diagnostic information via 2 sets of blinking indicator lights.
You may very well have issues with capacitors on this set being that it is or very similar to the V26 chassis. Since I have spare test lamps laying around, I would normally try that first. If the lamp still would not stay lit, I would then suspect the electrical chassis (capacitors). When I suspect the chassis, I can usually verify it by pulling it out and partially disassemble it and find blown capacitors
