Question about Emerson TS1997 19" TV

1 Answer

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... 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.

I am trying to help my neighbor. She has a Sanyo flat screen tv Model DS20930. The picture she gets is a thin line across the center of the screen.

Set the brightness, contrast and colour control of that TV to minimum. Watch it in a dark room whether ther are thin white lines across the screen, at about an inch apart, from bottom to top of the screen. If there are lines, that TV needs screen control adjustments. That is, now the screen voltage given to the picture tube went high to some reasons. If you have confidence that you can adjust it, I will guide you.
Open the back cover of that TV. Locate the LOT [Line output Transformer], usually one red thick wire is connected to the top of the picture tube with the help of a rubber ****** and clip. In most TVs it can be located and can be seen as the back cover opened. There are two variable control, fitted, integrated to LOT. Normally the upper one is marked as focus, and the lower one is marked as screen. You shoud adjust this control to avoid these lines.
It is a live service, that is the TV must be switched on during this time, and take causion in every respect not hurt by yoursef and the TV. Keep the children away from you, and an other adult person beside you is better. A liitle turn counterclockwise will remove this problem.

Black screen with a line of the picture running

The vertical sweep generator is dead. The circuit that controls the lines being drawn from top to bottom has malfunctioned or died. This not something you can fix, you will need a professional.

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.

Good Luck!

No picture

a bright thin line in centre is called horizontal line. first of all do not keep tv on unless it is rectified. BUT If you want to put on tv keep brightness minimum to protect your screen for any demage. now solution 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

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.

Tv not working

this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

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
