Question about Sharp 27J-S100 TV
Pls help me
I am assuming that this is a conventional CRT type TV. Most if not all TVs of this design has a small squarish PCB right at the very rear of the tube encased in a shielding of some sort. There would be three (3) transistors in said PCB responsible for driving the 3 color guns of the TV (red, blue & green). In some instances, it could just be a single power IC. Either the transistor or the IC would be heatsinked. The transistor for the red color is defective and would require replacement (if IC then the whole IC). In some instances, it could only just be a cold solder.
This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
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.

your problem is in red video output circuit.
as you are seeing lines with red color
those lines are called retrace lines.
