What is the make and model
SOURCE: tv will not turn on
the rca itc222 chasis has a processor that shuts the set down when it detects a problem for Safety. it can be one of about 30 problems. the computer also records the errors in memory and a technician can interface with a computer to read these errors. after the set attempt to come on 3 times then the set locks up and you have to unplug to reset.
SOURCE: Standby Indicator flashing SONY KD-32NX100U
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.
1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.
2 The protection circuit detected a wrongvoltage 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

On LCD Payparticular attention at inverter and power board, power board can beinspected looking for bulged or leaking capacitors, then tested with amultimeter.

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
