Question about Toshiba 42HP95 Television
42HP95 just turned off by itself, then red LED is blinking. Unplugged overnight, still blinking LED. Everytime I re-plugged power cord, heard clicking sounds from back but still won't turn on, blinking light at front.
Please give solution and if parts are needed, where can I get them. Thanks.
The clicking sound is the internal protection switch that kicked in because a fault had been detected.
First 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 you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor 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.
Common faults that can occurr are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
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.
