Hi there, you could take the back off(after first removing the power plug from the socket). Then check the power supply for a blown fuse. Any more investigation into the malfunction of switch mode power supplies as used in TV require expert attention and should be referred to qualified personal. But do check for a fuse out first :)

regards
Graeme

OK... that means that the mainboard of the tv is damaged. The cost of a new mainboard will be around 500$+Labor(around 200$). If you are familiar with electronics i can provide you with a schematic if you can provide me the brand and model number of the television..

Go into menu and with original remote call up convergence--either it has a problem(will not adjust) or you may with the remote be able to manually adjust the convergence back: sometimes if a power outage/surge it scrambles the convergence memory.

My Toshiba Theaterview turns on with sound, but no picture.


A model number is needed to assist you but a general answer is:

Likely damage is in power or standby power supply the set uses.

A visual look in that area might tell you what is bad---follow power cord inside to the power board where it goes directly.

My tv clicks to come on but no sound no picture


If there was a power outage the problem is likely in the power supply.

The power light on the front comes on or not?

If no power light unplug the set and follow power cord inside and check the fuses---the click is a power relay activating---set may have up to 3 black relays on the power board.

Let me know your skill level and I will be happy to help.

We have a rear projection tv that has no sound or picture after a power outage??


Suggest unplugging for 15-30 min to allow capacitors inside to discharge and reset and systems from the outage. Then plug in and see. It could be the power supply or a burned out bulb from the quick pulse of loss of power also.

53FDX20B NO PICTURE AND SOUND


It powers up but no picture? In my experience with Hitachi TV's this has been an issue with the convergence IC's failing. You will need to have a technician replace those if needed.

No picture no sound


You will need to trouble shoot the various power supplies most likely something minor in either the stand by or start up circuits. I recommend that you get a service manual at the following link as they will email it to you and also help you diagnose it with free tech support. Here is the link.

at this point the only thing you can do is take the back off and check to see if any fuses are blown.
