Re: The screen changes to a blue colour
A lot of rear projection televisions emply blue mute when signal is not present.

Try getting into the menu and turning off the blue mute feature.

I've had this annoyance happen a number of times with the ATI Catalyst graphic cards on Windows Vista, and tend to forget how to fix it, so I'm parking this blog here, and hope it will show up in Google searches for people also suffering from this annoyance who can't seem to get any of those geek squad sites to answer or fix this common problem.
Once again, this is a solution I found for ATI Catalyst graphic cards on Windows Vista. Not other systems. Not other graphic cards. This is not a help desk. This is a blog. If you don't have this system and this graphic card, keep looking. And find a geek help site, this is just a blog. Did I mention that this is for ATI Catalyst graphic cards on Windows Vista? Let's hope by repeating this and bolding it, I will fix the problem of people continuing to ask for other answers.
It's likely rooted in the graphics card problem or maybe even the monitor, but here's what it is:
All of a sudden, your screen tints blue. This isn't "the blue screen of death," but a blue coloured tint that makes everything then purple if it is red, etc. -- and it becomes impossible on your eyes. Second Life becomes impossible to see, etc.
You try going into the display settings to see if the colour tints are off -- nothing works there.
You get the latest driver -- in this case HD ATI Radeon 5700 just got a new driver 7/17 -- and yes, if you buy your computers at Best Buy like I do, and aren't a geek buying parts on Newegg and assembling it all yourself, that's the card you got if you got your computer a year ago.
But that new driver does nothing to solve the blue tinting.
So you check cables, turn off, turn on, take out cables, make sure they are all in place, blow on everything, etc. etc. Nothing makes it change.
So you go to the settings for the monitor -- those impossible menus with the interface where you have to keep plussing and minusing and pushing and getting it wrong and going up and down menus -- really, the dumbest interface there is -- but nothing helps there.
OK, let me help.
This is if you have a PC, of course, we aren't geeks and we don't get Macs.
So you right-click on your desk top and go to PERSONALIZE on the menu -- this is on Windows Vista. You ignore things like colour or changing the colour of Windows -- that won't help.
Go to the bottom, to DISPLAY SETTINGS.
On your first screen, go to ADVANCED SETTINGS.
On your next screen, go to the top to AMD VISION ENGINE CONTROL CENTER.
Truly, ignore all that other stuff that sounds like it might help like "Colour management". Ignore what geeks tell you everywhere which is to change the refresh rate -- you may find you *can't* do that or if you hack out of it to change it will harm your monitor. Ignore.
Next go to the bar at the middle of the page and click again on the AMD VISION CONTROL CENTER.
You get a menu with war game stuff on it.
Over on your left in the middle go to MY VGA DISPLAYS
Select IMAGE ADJUSTMENTS (VGA DISPLAY)
You will see that the little picture of your desktop with a grid over it with arrows is blue/purple.
So grab the arrows or click on the plus or minus as indicated and push it a bit up or down or sideways and watch it turn orange/red -- then it is usually back to normal, you will see pages as white again, the desk top will lose its tint. Yay!
You may have to fuss here a bit, it can take some doing to grab it right and get it back to normal without the tint.
Be sure to click OK on the other screen before that and exit.
Sounds like the optical block is going bad. when thos happens you usually see like a band of pink and a band of blue on the top and bottom. or splochy parts of the screen with the failing color. Sony has released a lot of info on this and you can do a google search to confirm. Ive found several examples of failures. This problem is not solvable economically.
Check the menu set up of the TV. There should be an alignment feature that aligns the blue, red, and green colour projectors. If the blue is out of alignment that is likely why you can see it on the dark backgrounds.
The set up normally puts a white cross on the screen and you select each of these colours and then move the cross over the white on with the arrows on your remote. Once all are aligned correctly you shouldn't be able to distinguish between different colours and hopefully this should get rid of your blue shade.
Try looking into the blue CRT lens while its on and see if the coolant has congealed. You will be able to tell if it has bacteria growing as this can cause the blue to be unresposive and make your screen have a blue haze. The coolant will need changing if this is congealed with bacteria. This is a common problem in all projection tvs blue and green are more prone to this sympton red is not.
