SOURCE: Sanyo DP42746 - Screen went black and no sound. Power light on.

The TV is on protect mode.

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 with no receiver box or dvd 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 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.

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 occur 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 state because of the video 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.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

SOURCE: DP46849 has black screen with power light on.

It may be in safety shut down mode due to shorted circuits or power supply failure due to such thing as bad DC filter caps. You will need to do in-depth troubleshooting.

There is a green tint to my screen. Seems to be more evident in dark shows and on shadows.


Pull the front speaker grille off and remove the access panel. In the customer menu turn the color off so you have a black and white picture. get a flashlight and adjust the screen controls for the red, green and blue tubes until you get a nice black and white picture. then turn the color back up.

Picture is very dark and color not too good.


Take the front speaker grille off; it is stiff but will pull off. Take off the access panel underneath; four or five screws. Inside you will find a screen/focus block control assembly. Get a flashlight. Turn up the screen controls SLIGHTLY. for RED, GREEN AND BLUE. The best way to do this is to turn off the color first and make sure you end up with a good black and white pix ( not tinged green, red or blue) then turn the color back up in the menu.
