Sounds like your red gun may be shorted, Try adjusting the red gun down a little see it that helps.You can also switch the blur CRT socket for the red if your screen is still mostly pink then you know for sure its your red tube that needs replacement. If its mostly blue then you have a problem in the red drive circuit.

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

How to fix AOC LCD TV random vertical coloured lines, no response to controls


Sounds like a screen fault. The adhesive that attaches ribbon cables from the drive electronics to the screen has failed. Unfortnately this isn't fixable because the connection and spacing is too fine to get a 100% reliable connection. Some DIYers have used neoprene rubber tubing as wedges to hold the connections in place. That actually works. Search Youtube

Random Side Panel Inputs


You either have a bad Main board or simply a bad touch control button in other word one of your side buttons is defective and it is blocking any other signal to the main board, but usually its a bad main board. In some cases ther is a FIRMWARE update from Panasonic, you may want to call Panasonic or check there website for any type of FIRMWArE UPDATE.

I find the colour contrast is very dark could you send me ideal colour settings for perfect clarity thanks


Hello
Adjust the contrast to 55 to 70%; brightness to 45 to 55% and colour to your viewing taste. Now the brightness will be very low I thinks. Advance the brightness and contrast after setiing the colour to Zero. Adjust for a well defined B/W picture first. The advance the coulour. Take reference of the face colour of a news reader at studio. The picture will be perfect. OK.
