3 horizontal lines across screen and triple shadow on left side
When we turn on the tv, there are 3 prominent horizontal lines across the screen and the left side has triple and quadruple shadows for 5-10 sometimes 15 minutes, and tends to lengthen as time goes by.

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?
Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.
Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.
Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent. Line faults to all LCD TVs will be similar, irrespective of its screen size and brand.
t con board failed if its half and half. can also be a lose cable on the screen to the tcon board from the lcd screen side. Tcon is in the middle off the screen on the back.
This is either 1 of 2 things, first it could be faulty panel tabs , in this case, there is nothing you can do and is unrepairable....2) you could take the back off the tv and you will see 2 ribbons going from your t-con board to the panel tabs (top center of tv) remove them carefully and reseat them. This is a common problem. Tv repair tech 15 years! Best of luck.
It sounds as though you have a poor signal issue. Firstly try rescanning all the channels. If no difference check the aerial/dish connections, then rescan. Lastly check the aerial/dish externally for misalignment and connectability.
sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines.
good luck.
