Those 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 section 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 procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

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
connected.
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

LCD/Plasma Electronic Replacement Parts: Plasma & LCD TVs, Appliances |
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.
SOURCE: INSIGNIA LCD won't turn on
replace 2 condensers in the power supply with greater voltage ones.original are 1000uf 35volt...use 1000uf 65volt...99cents each
power circuit is made to fail with typical tv industry tactics...the warranty is reflected by the life of their condensors (capacitors) average life is 2000 hours..
easy...huh
if your a smoker...you must clean the button cover as they get stuck on with your stupid tobacco residue. 75% of all LCD tv's that smokers own fail this way...
\tough huh?
TRY TO STOP SMOKING...
SOURCE: No picture, no sound, does light the insignia sign. Why?
In about 90% of the time the power supply is defective if the TV fails to power ON.
