Question about Emerson TS1997 19" TV
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... firstname.lastname@example.org Thanks, in advance...
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.
