Sounds like it. Replacement of both STKs is required. (They should always replaced as a set).

Panasonic Viera PC-to-TV Via VGA has Purple Tint

Purple Panasonic PC>TV Problem:
The VGA cable uses three primary color RGB channels.
Red, Green, and Blue.
The picture is made up of pixels or dots arranged in a grid along the "X" horizontal axis and "Y" vertical axis.
The computer mixes the intensity of each color channel to create a unique color per pixel.
All RGB at 100% creates white.
R+G creates yellow.
R+B creates magenta, ie purplish.
G+B creates cyan.
So a purplish tint sounds as if your Green wire has no signal, which may indicate a faulty VGA cable or VGA socket.
Put another way, (R+G+B)-G=R+B=magenta.
So try another VGA cable, spray all socket pins with "Servisol " or similar contact cleaner.
0%<--------->100%
Cyan<------->Red
Magenta<--->Green
Yellow<------>Blue
All 0%=Black; All 50%=Grey; All 100%=White.

Installed a new set top box last night and all the channels are black and white - no colour at all - confused!!

Check your cables between the receiver and your TV to make sure the colors match. If you are using a component cable (green, blue, red, white, red), not matching colors at both ends will give you what appears to be a black and white picture. I hope this helps.

The picture has a green tint to it on all channels

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

Philips 23PF9966/37 color problem!

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

Mixed colors and separation of colors

Common problem known as convergence. The most common reason is the failure of convergence ics. these ics fail all the time because there big and get fairly hot. there is a possiblity that it can be reconverged if the convergence cuircit is not damaged
