It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Most likely you have a fault in the back light circuit. To verify this, turn on the set, when the screen goes black, take a bright flashlight and shine it on the screen. It may be easier to dim the lights in the room so that you can see the faint image on the screen. If you see the faint image, you indeed have a back light problem. You will need to get a diagnoses performed on the set to track down the problem

Tv turns on screen displays Please Wait then goes black


There's a problem with the power board communicating properly with the interface board aka 'main board'. There's seems to be a logic problem here _Data-Bus interference. This could be because of DC voltage shut down or an under-voltage condition on the power supply board. Also the serial data too and from the Timing control board could also cause a similar problem. You can send the power board and interface board too me and I'll repair the problem for you. Or if you have some test equipment I can show you what to test.

Get back too me when you can.

Hitachi 46ex3b/4k turns on,sound, no picture black screen!


First check for a faulty capacitor on the power supply board as it sounds like that could be the first place to start. Before you touch any capacitors PLEASE find articles on the internet concerning discharging them as one stray discharge incorrectly could not only destry your tv but hurt you or even KILL!!! Ignore any articles that tell you to use a screwdriver. Good luck.
