Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

Arching color wave on bottom left corner & also on top left corner(color changes)

My tv started doing this about 3 months ago. The picture or lettering is really distorted on both top & bottom about 1/3 of the lower & upper parts about 2 inches on each. You can really notice it when there is a dark backround or ESPN is scrolling info on the bottom. Yesterday I started to get lightning color rays going diagonally across the screen also, I turn the tv on & of real fast and this goes away but the other is ALWAYS there. What do you think is wrong with my tv. Note: My tv is only 2 years

    I am having the same problem. I was hoping to find some info on here before I made the call to a repair person. We have had the TV for about 4 years or so......I think. If anyone can help, please email me.

Convergence amps are failing which is very common. Several hundred dollars for a repair.

Yellow arch on bottom left of screen


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Re Degaussing


Now Degaussing and convergence are two different things, if you say its degaussing then you should have just a color differential in a certain area, meaning the color should not be arched, everything that passes through should pass throu only with the changing of color. Now if its a convergence the the color may lift upward in an arch, likely separated from the other colors, Red, Blue,or Green. So now which do you think you have? Deguassing usually give you a highish green color or yellow

Problems with green arching lines


yes there is a small black box with 6 controls on it, take off the bottom front of the tv, behind that you should find a black piece of plastic you can remove by taking out 2 more screws. the black box should be in the upper rhs.now i don't remember if the top 3 are the screen controls or the focus controls. the rows should be labled, you are looking for the screen control row. the green control is the middle one. you can try turning down the control till you no longer see the green lines. try adjusting in a dark room, it will be easier to see the lines & when they are gone. if you problem is not solved by trying this, then i agree with your tech & the green tube is bad. good luck.
