Have a Toshiba TN55V71 whose color seems to come and go. Sometimes it is just pea greens, yellows, and blues. Other times, the color is flawless with brilliant reds and oranges. What gives?

Typically:

Lime green (pea-green) is front speakers.
Orange is for center speakers and sub-woofer.
Black is for rear speakers.

Pink is for microphone in.
Blue is for line in (MIDI or similar).

the problem is at the crt base .there r three red,blue n green o/put.verify if there is dry in the soldering n check the red cathode voltage it must b around 150 .if not then check the resistor that feeds the red o/put.it could b 12 to 15k. all crt have 3 driver color red blue n green,whenever one driver not working the color changes.that wat happened to ur tv now i do not know wat model u have.the drivers may b transistors or now its ic that r being used like tda 6103q.best of luck

Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Loose electrical connection or its loosing its grip to hold your screen. If you can do it on warranty then try. Or have it check by a technician.

the blue gun is not working properly which explains the dominance of green and yellow colors. you need to look after dry-joints on the blue gun circuit board, sometimes oil leakage from the lens may also affect the board

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

lg70 nice tv excellent processor just to bad there is no intensity control on color management oh well still better than what the three s are pushing block out the hype lg will be number 1 in a few years haters are starting to come around and well leds coming,

p.s. i dont work for lg just tired of losers bashing stuff because they dont own it.
im isf certified those settings are right on the money straighter than a ruler

you will need two convergence ICs they are both STK392-110 and you should also order four 2.2 ohm 2watt resistors. You can get replacement ICs and resistors at the following link with free instructions.

1)Please verify your model # from back of set......

2)Reduce the color to minimum or tune in a black & white chan.
you should see gray, not yellow hue

3)Remove lower front grill cover & access panel.....locate the
focus / screen control block...turn blue screen control slightly
CW......red,green and blue must mix to equal gray

4) reset color to normal level.......reassemble

if you have H/D one of your cables might be loose red/green/blue  i suspact red
