Screen slowly turns blue...

Like when a little kid holds thier breath... starts out great when you turn it on and in about 10 minutes the green gun is dark and the screen is all blye. How do I tell if it's the gun or the cicuit behind it? Can I switch the red and green guns just to test it out?

Thanks,

I'm holding my breath now......

    This is truly amazing. I got this TV from Craig's list for free because the screen turned blue. Noticed that the color was a little over driver...retrace lines. Found the post on FixYa that told how to get rid of the lines and guess what? Pictures not blue anymore. Seems that if the color is over driven too much, the entire set tuns off. If it's overdriven a little too much it can shut down one of the guns. In my case it was the green gun. So, before you replace a gun, turn all those screws on the bottom row CCW and reset the set. I'll bet my set isn't the only one with this issue. THANK YOU FixYa. I'm going back to watch my TV now.....

I had blue lines showing up on my screen, then the other night my screen started to flutter the blue, bright to dim and back. So I followed this link to resolve the blue lines and the blue flutter was resolved as well. Hope this helps.

We can set the convergences great but after about 10 to 15 minutes ithe reds lines start moving a little again will not stay in position. It's a widescreen Mitsubishi rear projection tv ws-55857.


The problem - you're setting the convergence settings, but you're not saving them, you're
simply exiting the menu screen. Be sure to save your convergence setting for each
of the three colors. It sounds like you're setting RED last, and not saving its convergence setting,
whereas the GREEN & BLUE are holding their convergence settings, since you're saving them
correctly before proceeding on to RED....

The only color I have on my tv is green. How do I fix this problem


mcid1515,

If you have an older set you probably need to turn up the screen drives on the red and blue guns. The largest part of the color signal is the green with red and blue much less. If the gun drives put out less as they age, and they will, periodically the screen drives need boosted. I have a tip at

http://www.fixya.com/support/r6814105-adjust_screen_drive_crt_projection_tvs

This will walk you through the process of setting the screen drives.

Thanks for using FixYa and for the great rating.

When the tv is first turned on the picture is great. After about 5-10 minutes the picture looks like a 3 D movie when you're not wearing the proper glasses. Sometimes turning it off for 10 minutes and...


the 3d effect is caused by a mis alignment of the tree tubes you probably have a broken FRAME holding the tubes in place so that HEAT or VIBRATION can move them and the alingment is off dont forget you have one tube for RED one for GREEN and the other for BLUE if they are not aligned properly they can look like a 3d pcture without 3d glasses ha! sorry for the bad grammer...

Good luck!

KP-65WV600 Red and Green Lamps fade out after about 15 seconds


Hi, if the tubes fade from full brilliance to black over a few seconds, the possible sounds like dry joints in the CRT heater circuits. possibly caused by dry joints (bad solder joints). Most repairs involving rear projection TV's can be a pig (mainly relating to access to work on the circuit boards)

Hitachi 46510 blue screen-Shuts down


Good Day, 6slimshandy9;

Try and look this;

Shuts down at turn on, LEDs D955 & D956 come on & turn off asap, the rest of the LEDs on power supply will go off slowly.
Cause: Found QEA6 (2315381) and QEA7(2315391) shorted in Blue CRT PWB.

I hope this was helpful, big IRISH. Or try unplugging the blue crt socket and if it turns off. If it stays on suspect bad CRT.

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

Blue gun control


Remove the front speaker grille and also the smal;l access panel and you will see a small control box with 6 switches 3 control the focous and 3 control the screen control. The screen control will be laid out like the CRTs are Green in the center and blue and red on either side just turn the blue down very little or you will make the CRTs shut down.

BLUE SCREEN


I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
