After playing a DVD for 30 min the colors turn bluish gray, I have replaced the cables and moved connections on the tv with the same results. The tv works perfect with the cable box. It was working perfectly untill I moved it to another house in the cold. it was not banged around or miss handled so I doubt that was the cause, but it was turned on and played 15-20 min after it came inside. any sugestions

That isn't convergence that does that. There are "screen" trimmers, if someone has messed them up you can get all one color, but the usual cause is the picture tube going bad. The screen trimmers are on the PC board on the gun (narrow) end of the CRT. Some trimmers are color drive and others are color black level, or "screen". Don't adjust the color drives, it is a delicate balancing act to get them right. Find the one labelled blue and turn it down. If all you can get is too dark, turn the red and green up, just enough to see a dim color haze in a blank picture. Balance them out so the haze is gray. Then turn them all down just a hair so the screen is just black. Then try a picture. If you can't get gray on a blank screen then go to the high voltage transformer (the one that can kill you if you touch the wrong part) and adjust the "screen" control on its side up (it adjusts all the colors together). If you still can't get gray, one or more of the color guns is weak, and you may as well chuck it.
Of course it could also be a bad blue drive transistor, but fixing that takes more expertise than you can get from a forum.
Actually, just getting the TV open and propped up so it doesn't fall over is a job in itself...
<span>How to fix the orange screen back to normal!</span><br /><br />The other day i turned on my Philips DVD player model number: DVP5992 and the screen was orange red, instead of blue/grayish! I have tried to google the problem, but no luck. So what i did is, i disconnected the power cord and the HDMI cable and waited for like 30 min. After 30 min i plugged it back in and my screen went back to normal, being blue and gray!<br />If you have this problem, do this, and your screen will turn back to normal.<br /><br />Also if you want multi-regional code to play all regions DVD's, do this:<br /><br />
<br />select the Preference Tab
(4th setting to the right)<br />keep that tab open and Press 1,3,8,9,3,1 <br />Press up/down on remote key to select "0"
<br />and hit "OK" then hit setup to exit.
<br /><br />good luck and enjoy!<br />Naztech<br />
I am going to tell you a simple thing to do to know what your problem may be.
With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?
If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)
I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.
The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.
This is called gray scale; picture with color off has to be gray or black and white.

Replace your Tvs convergence board. Go to www.partstore.com, and check for your current TVs model number. Check for its convergence board, and simply install it by carefully removing the old board that looks just like your old one, and replace the cables where the cables for the old ones were. In many TVs, the cables are gray, blue and 3 multicolored sets, which go to connectors marked blue, green and red. The gray and blue go where the gray and blue cables for the old board were. For the multicolored ones, just replace them where the previous ones were placed, marked blue, green and red. All you need is a screwdriver and about 30 to 45 minutes.
Are you using component cables (red/green/blue)? Check your connections to see that they are all seated properly. When using component cables, if only the green is plugged in, it will give you a black and white picture. You will get color once you plug in the red and blue.
What kind of sources are you using? what kind of cables are you using? Need these kinds of specifics to ehlp you out.
you should first check all the cables inside the set to make sure they all are seated properly, check some other sources like a dvd player and see if it does it on a dvd, after that it is probably a defective main board
