It sounds like a bad panel or possibly a bad digital board. This board is mounted on the back of the LCD panel. Have it checked by a repair shop.

You either have a malfunctioning LCD controller(T-con) or the panel itself is faulty. The T-con is very inesxpensive and easy to replace but the panel is gonna cost you nearly as much as a new tv. Let me know if you want to give the t-con a shot so that I can guide you to fix it.

It could be a power supply problem or an inverter board problem or something internal having to do with the backlighting of the unit. remove the inverter, and look at the back side and you will see a hot spot, now on the other side of that hot spot, re-solder the service mounted components and that should take care of your problem.

Please get back to us if you have further query else please accept the suggestion.

Thank you for contacting

How to find area between 2 curves

The TI84Plus has a Shade( function which allows you to represent the area you want to calculate.
The simplest syntax of the command is

Shade( lower_function, upper_function, Xleft, Xright, pattern, patern_resol) where Xleft is the left limit, Xright is the right limit, pattern is the shading pattern and pattern_resol is the resolution of the shading. Only the area where lower_function is less than upper_function is shaded. Unfortunately this command does give the value of the shaded area.

To find the area between two curves
  1. Draw the curves
  2. Find the left intersection point using [2nd][CALC][5:intersect]. Sorry I will not describe the procedure. The X value of the intersection point is stored in Ans memory.
  3. Press [2nd][QUIT] to go to main calculator screen.
  4. Store the Ans result in say A: [2nd][Ans][STO->][ALPHA] A
  5. Return to the graph by pressing [GRAPH].
  6. Find a second intersection point. Result is stored in Ans memory.
  7. Press [2nd][Quit] to return to main calculator screen
  8. Press [2nd][Ans][STO->][ALPHA] B to store the X value of the second intersection point in B.
  9. Use the CATALOG to paste the fnInt( command to calculate the integral : [2nd][CATALOG][[APLHA] F and scroll to select fnInt( and press [ENTER]
  10. To complete the command you need the identifiers Y1 and Y2.. You access the identifiers Y1 and Y2 by pressing [VARS][Y-VARS][1:Function][1:Y1] and [VARS][Y-VARS][1:Function][2:Y2]
  11. The command should appear as fnInt( Y2-Y1,A,B)
  12. Press [ENTER] to obtain your value.
Hope it helps.
Thank you for using FixYa.

"Finger Print" sized shaded area on screen

A shaded or dark spot on the screen is usually a bad pixel area and is caused by being hit or pressed to hard in that area. It could also be that the liquid crystal (LC in the LCD) in that area has become stagnant, try rubbing the area and around the area pressing firmly, just enough to see a color change in the screen area, but not too hard that the area turns black. Rubbing the area will move the liquid crystal around and sometimes refreshes a darkened area. If rubbing doesn't work, then it's a bad pixel area, and will eventually become a dead pixel area with time.

how dark? can you see anything throught the shading.. still might be a cap in the video out circuit but the one Im thinking of shades the right side and brightens the left.

sometimes RF or HV arching causes shading on left, mute your sound and listen for sizzle noise in the back.
