Question about Televison & Video
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure 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.
If that does not work, and TV is still not responsive, then there is a fault condition.
if the led is on , or flashing, this indicate 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 chargesaccumulating on capacitors, or because of a wrong voltage read by themain chip on your monitor controller board. this started the protectioncircuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV 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 instead you have an LCD TV, and you see a faint picture with no backlight, then there is a problem with the inverter.
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.
