Your problem is called a vertical sweep problem and is caused by a defective vertical output IC,a bad vertical output coupler capacitor, and/or the b+ from the flyback transformer feed resistor and the filter capacitor. You get a schematic and post it here and I'll show you what parts are the most common in this chassis. You can get a service manual from Sams photo Facts on line and downloadable. Good luck

Pink/Blue horizontal line on TV

Considering it is a 32 inch set and costs now under 300 dollars it may or may not be worth fixing.

To give an educated guess: either whatever it uses for an inverter board may be bad or damaged OR even the main board that processes all signal into or out to the screen may have either a bad connection(unlikely but possible) or be causing this.

A fatal issue could be something wrong in the screen unit (panel) itself.

I gather set is not under any warranty at this time.

One horizontal line center on the screen

The vertical deflection circuit has failed, or has been shut down by a service code entered from the remote control*. Usually you can get out of service mode by turning the set off and on again.

*Normally, you have to enter a special combination of front panel and remote control codes to get into service mode, then enter another code on the remote control to get the horizontal line. The horizontal line is used for adjusting the screen controls for each color so you get proper color in the dark areas of the picture.

Hi,

Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:

12V line and pin 29 of IC401;
110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
other components that affect the horizontal size are:

IC201
Q 405, 406, 407 & 408;
D409
L401

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
