Question about Emerson EWF2704 TV
When I turn my TV on, the picture looks as if it has compressed into about the center 1/8th of the screen, with a solid white line on the top of the "compressed" picture. The rest of the screen is black. I have soldering expertise with small electronics but not much knowledge of TV inner workings, so if I needed to replace/resolder a resistor or chip that wouldn't be an issue. What's wrong with my TV?
Look for vertical output LA7804 7-PIN IC near right rear of set on heatsink. Look for bad solder joints in that area also.

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
