BLUE TINT ON SCREEN ALL THE TIME, COLOR ADJUSTMENTS FINE

If u turn tv off then back on, tv works as supposed to. but after a few minutes of operation it reverts to the blue tint/haze.
this is very annoying, but seems to not bother picture clarity.

Sounds like a bad blue CRT (picture tube) ITs expensive and difficult to replace. CAll a Sony service center for an estimate. but expect to spend $500-700 to replace it.

Video is taking on a red tint which is getting worse over time


check the cable connections. look at different inputs. VGA and Component cables have the colors split, so if it's turning red, green, or blue; it's likely a cable or connector.

BLUE TINT ON MY SCREEN


Philips tv's have always had this problem. Between the picture tube and focus lens there is a layer of coolant fluid. The coolant fluid, over time, will break down and turn a brownish cloudy color and it usually starts with the blue. Something to do with the color frequency. Have a good repair shop check it out and if the fluid is the problem have them change all the fluid in all 3 picture tubes (there is a red, green and blue tube). Don't feel bad, like I said all the philips projo's had this problem. Thanks

I have a KP-65WV700 and the screen looks a lil to green


OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.

Mitsubishi tv problem


im assumiong you checked the tint in the menu options. if not go check it. other wise it sounds like you have a weak tube, or you do not know how to adjust the screen brightness. this is how i adjust the brightness (you dont need to touch the focus). turn the red up until your whole screen is tinted red, then do the same with the blue and the green. then go through each one and turn down just a little till your pic darkens a little. good luck

TV Problem with shutting off by itself


Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.

What you may have needed to do was adjust the green & blue crt screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white px. Now adjust each crt screen so that you end up with a true black & white px. Then adjust each focus control to get a sharp px, have your tv on a channel like the home shopping network so you can adjust each crt focus one at a time for clarity by cover the other 2 up. Then go back into picure adjust & turn color ahlf way up, you should see a better px.
