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

If you want to repair at your own expenses, just locate any good qualified repairer.

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.

No sound on my sharp aquos lc-45gd4u 45 in


Assuming you are using the internal speakers, check and make sure you have the audio enabled. Some TV sets have a option to turn off the internal speakers. Also make sure mute isn't turned on. If you are using external audio setup, double check your connections.

Connecting an hd-tv


use optical or composite digital audio cable only from tv to receiver because with rca (red and white) you get stereo only

Cant get the wiring figured out.........


I have a similar set up. For yours, I would run one optical from your Sat box to your 407 and connect the DVD player optical to the Kenwood as well. This will allow you to get whatever your watching, DVD or Satellite to your speakers. For Video, use the component cables to connect DVD player to TV. For the SAT box, coaxial to TV or S video to TV will give you about the same video quality. I hope this helps. A couple of suggestions: Your new screen size will greatly magnify the quality of your video, what looked good on the Sharp may not look good on the Samsung due to the size difference. I REALLY suggest you get a new SAT box with a HDMI connection. Also you can get a blu ray player in the $120 range. The Blu ray will play blu rays and upconvert DVDs to a higher quality picture through its HDMI connection. You will be amazed at the difference HDMI will make on how your TV will look!
