I've had my Emerson 27'' flat screen for 3 years now. Lately, I have been having problems with the screen. Almost immediately upon turning the TV on, the screen widens out and I lose some of the picture on the right and left edges. It is almost as if it stretches out too far across the screen. Needless to say, it is very annoying. Is there anything that can be done that won't cost too much?

Re: Screen Widens Out Constantly
You might be getting more supply from regulated power supply if you get wide pictureor width have to be adjusted by width control.
but if it stretchs out & lose some of the picture on the right and left edges it might be due to horizontal output section.
1 loose contact in connector.
2 some capacitor might be defective in h/section
please do not open the set unless you know about high voltage in tv set.

Backlight CCFL lamps fault. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. http://electronicshelponline.blogspot.com/ Pull up older posts.
This is a problem with the vertical circuit and is either the vertical IC or a few capacitors that have failed in the same circuit. If you can solder you should be able to fix this yourself. The part cost will be in the $20-$40 range.
Update this if you wish to attempt the repair and I'll supply additional details and instructions.
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????
That Emerson was actually made by Funai, and you may have to contact them for service. Emerson used to be a good brand, but they seem to just want to sell or lease their name to any company that wants to use it. Generally speaking, if you're looking for consumer electronics, don't shop at a store whose name ends with Mart. Even though your set is over a year old, it would probably not be worthwhile repairing it. If you decide to try anyway, their telephone number is 1-800-242-7158.
