No pic or sound with power on my Toshiba 50HX70 Tv


The plug configuration shouldn't make a difference; the third (round) pin is only an earth/safety ground. The two primary plugs supply the AC. You probably have a failed power supply which may be a separate board. Check to see if this is the case, look for a part number and see if you get any hits on it on search.

Tosheba 50hx81 no picture or sound. press on button and hear speakers do something but no sound


It is likely that you don't have the right input to the television.
First get a source that you know works. How about a DVD player.
Get the cables from your DVD player (should be yellow RCA or "Phono" plug for the composite video out put.) Connect only the yellow video out put to your t.v. input and then press the av input button until you see the picture (note: besure that the DVD player is turned on and you have a dvd in it. We sometimes miss the very basics).

Once you get the picture than connect the audio cables, should be red and white to the corresponding colors. Do you have audio now?

If this test worked fine, it is likely that the solution to your other problem is that you have it on the wrong av input and need to press that button a few more times to find your satallite or cable input. There is a possibility that you are trying to use the tuner in your T.V. and it may be again as simple as choosing antenna input and that too needs to be hooked up to a good source.

Write me back if none of this helped.

No sound or picture


your relay is turning off most likelt due to on of the stanby voltages being out of parameters I would check the low voltage regulators and the horizontal output transistors.

Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.
