The problem with my Phillips 9p6034 9102 with chasis number ptv 835 is that when you look at the screen straight on you can see the red green and blue lamps. When you stand up and look down at the screen...


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. 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, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Red and fuzzy picture can you help on my 50 inch phillips magnavox projection TV


This is a very common failure on Projection TV sets.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around video.
You can see some example photos and find a solution here on Fixya.

I cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws


yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

Too much yellow does not adjust with normal drop screen adjustments. can i adjust the light beams.on my philips 50"


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} 1. Turn the green screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
2. Turn the red screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
3. Turn the blue screen control on the Focus Block until retrace lines appear and gradually turn it back
until the point where you can see the retrace line disappears, just before cutoff.
4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

Rear projector tv rear blue projector wont focus


Look into the top of the tube. Probably has fungus growth. Do a search. I posted that solution many times this week for that. Normally, focus don't go out on T.V's by themself. Either the tube is bad or has fungus or the screen control is bad.....but very rare will focus part fail...usually brightness/screen is at fault. Don't forget to check the green tube as well when looking. Take the back off and see if your head will fit. If not, a large mirror will do just fine. Put something on with writing displayed....easier to tell that way.

Philips magnavox 9P6040C104


i just found out why, turn on ur tv and remove back look directly into 3 lenses, if the picture is not nice and clear or looks snowy in all 3 u will not get good color or brightness. I removed my blue tube assembly and took it apart WHILE OUT OF TV. there is cooling fluid between lense and tube, this fluid over time will build a film on the face of the tube and get thick enough to block the tube from projecting picture. (MARK EDGES IT GOES BACK TO GETHERE THE SAME WAY IT CAME APART).Find some new fluid then carefully dissasemble and clean interior of lense, housing and tube thouroughly. Reassemble and fill with new fluid. Do not use old fluid it will be cloudy and snow globe effect. Only do 1 tube at a time this will allow u to realign cross manually as close as possible before u perform convergence. Leave the green for last that is the center and the red and blue are moved to match green. Also be sure to clean mirror and back of screen. Pete
