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.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

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

Screen


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.
