Picture squnches into a thin line in center of screen
Love my Emerson and it's been good; cardiac patient and don't work--$$$ tight. Have opened this unit before when On/Off switch broke and can solder and follow directions--some electrical knowledge.
Know there's high power in transformer... got a shock from another TV some years back that rang my bell so know to be careful.
Picture will be full screen and then the bottom starts bouncing up and down and then picture squeezes into s think line (like the old color set adjustment for the 3 guns) across the center of the screen.
Sometimes picture will re-expand and run a while; other times it won't. Hoping the fix is either a replaceable circuit board or a board component and won't cost much... hate to have to junk this TV and buy another one due to cost factor.
Am appreciative of any advice/help.. feel free to use my email... [email protected]
Thanks, in advance...

Re: Picture squnches into a thin line in center of screen
This set is known for cold solder connections on the vert output as well as the b+ supply line comming from the flyback xformer that supplys the voltage to the drivers. It could also be the vert output capacitor, The two waveshaper caps in the predriver stage of the vert, the filter cap off the flyback or the vert drive b+. Without going in and getting a schematic it will be hard to say. sets like that unfortantly these days are throwaways. NO NO NO dont throw the set at me I did mean that way!!! Its the cost factor of repairing getting the parts as well the the service diagram. it all adds up.

Reset to factory default through the settings or general menus from the remote control. If after resetting to factory default the issue remains it is likely you will need the services of a technician. Having said that, it saunds like a hardware fault but you will know for certain after a hardware reset
The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.
a bright thin line in centre is called horizontal line.
first of all do not keep tv on unless it is rectified.
If you want to put on tv keep brightness minimum to protect your screen for any demage.
your problem is in vertical section.
1 check vertical supply.
2 check parts in vertical section or loose contact.
3 yoke connrctor loose
4 ic defective
It is not serious problem can be rectified easily
You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
