Hi: When you say small horizontal screen, ¿Do you mean picture does not fill the screen completely from top to button? ¿Do images display normally though they are smaller in size? ¿Is color and definition of signal OK? Please answer so I can have a better picture of the problem.

TV Powered Off, won't come back on


mine did the same thing, I took it to a TV repair store and they said it was a power surge which damaged the power source board. (possibly caused by lightening)
total cost to repair was $70.00 well worth since was only couple years old.
TV is working well.------we'll see for how long????

Input select function... without a remote?


Whew! Found the NE116UD replacement for the EWF2704 Emerson TV (there are other models on the list as well), it can be ordered here for 24.95:

Hope that helps. This problem is certainly very irritating. I have never heard of a remote for 24.95, nice job Emerson -- never again!

Emerson EWF2705, when pressing power it sounds like it is coming on but nothing happens


Hello DEBM,

 

The problem with your television appears to be in the high voltage power supply or the low voltage power supply. The set tries to come on but the shutdown circuitry turns the TV off. The shutdown circuit is a protective measure put into place to prevent overcurrent and overvoltage conditions by shutting down the TV when these conditions exist. If you do not have a background in electronics, might I suggest that you have a TV technician to come to your location and work on the TV.

 

I hope this helps

Thabk you,

Emerson EWF2704 problem


Look for vertical output LA7804 7-PIN IC near right rear of set on heatsink. Look for bad solder joints in that area also.

Sound but no picture.


The problem with your television appears to be in the high voltage power supply .  This power supply supports the high voltage on the anode of the picture tube, and the voltages for the picture tube, and other parts of the TV. If you do not have a background in electronics, might I suggest that you have a TV technician to come to your location and work on the TV.

 

I hope this provides some help

Thank you
