Weak red color

Your red tube is weak or defective. If weak, gain can be adjusted up on the red tube.(cheapest cost) If red tube circuit is defective that will have to be fixed by a technician.(cost between $100 to $200) If tube is worn out, it will have to be replaced(250 to 500). Any work should be done by a qualified tech. Prices will vary depending on your area.
If set is over 5 years old, I recommend replacement.

You can adjust the green temperature at the color RGB adjustment.press the menu button then choose the video adjust then scroll down to RGB setting RGB stands for RED,GREEN AND BLUE..adjust it according to your preference..

Hi ,
welcome to Fixya, it sounds like you may have a weak CRT (picture tube)
If the TV is over 6 years old that may be the case.
There are RED, Blue and Green color balance adjustments that you can try .
referencing the exact model one could see how it adjusts.
hope this helps

Check the red colour out put section at LCD base PCB..the capacitor is weak or the transistor is gone bad,replace with new one..

I had the same problem with my TV, but the hue was blue. I was told that not only did I have to replace the picture tube that wasn't staying on, but I would have to replace them all because they would not mix properly. After much investigation, I found that there is an adjustment for a variable power supply to each tube that can brighten and lighten each tube. I adjusted the RED pot and my picture color issue was resolved! To access this adjustment you must remove the front panel on the TV. At the bottom corners there are two small screw covers that you must remove. Then un-screw the screws under the covers. Then pull the front panel off of the TV, (it hooks under the top near the screen so it will swing out from the bottom). Now remove the wooden panel in the center, (four screws). The pot adjustments are at the bottom of the TV. They are marked for Red, Blue, and Green. They are extremely sensitive, don't turn them much! If you over adjust you will get red, green, or blue lines on your screen. Adjust back down to remove these, (this is also the remedy for removing these lines that can appear over time). Good Luck and God Bless!

this unit may have a resistor on the green crt-board that has increased in value. check ohms(resistance) on all crt boards and compare to one another. these will have color bands that inicate value of resistance. you do not need to know color code, just match colors of resistors on each board then measure. you could also have weak green tube. turning down the master screen control located on the fous/screen block can reduce grn. drive. to adjust proper drive for each so the grey scale is correct, turn color to tv all the way down then adjust screen controls on block for black & white picture. when color is turned all the way down, you should not have any green, red, or blue over cast on screen. mch

adjust the blue bias on the high voltage block .
it has focus and bias for all three colors

your convergence board is weak

Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.

Hi,
I'm not sure about this model but most projection tv's have a focus/screen control block usually located behind the front grille where the speakers are. The grille usually comes off easily. If there are no circuit problems you can adjust the red green and blue picture tubes there. Also the focus. It will be written somewhere screen and focus: Three for screen and three for focus. If you find the screens then adjust them slowly clockwise for increase brightness on the red and blue and you may have to reduce the green. Adjust for best picture. If the picture does not adjust too good then the tubes are weak. Only if there are no circuit problems Hope this helps
