Question about Toshiba 51H93 51" Rear Projection HDTV
The TV is on protect mode. The clicking noise is the protection circuit that keeps turning the TV off to prevent damage.
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 damaged by the power surge. Check if you get same problem with no receiver box or dvd connected, after unplugging TV.
If that does not work, and you keep having the led in front of the TV on, and tv turning off by itself, that indicates a fault condition.
When the TV goes on protection there are only two possible reasons.
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. The problem had been caused by power surge.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light. In this case the power surge had blown one of the PSU capacitors.
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 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.
If disconnecting for few hours did not work, try leaving the set unplugged from main overnight, so to ensure that you are draining power from PSU capacitors completely.
Let me know how it goes.
