SOURCE: blury picture, convergance problem

What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps
Bill

It could be the flyback losing resistace in its windings. What is the chassis number I should have the service manual for it. Phillips/magnavox is hard to cross reference without the actual chassis number.

*CONVERGENCE SERVICE MODE PROCEDURES*

*Note: This procedure is required for all of the following geometry and
convergence adjustments.*

*Using the remote transmitter, enter the following seven-button sequence to
activate the convergence mode.*

* 06 - 25 - 97 - Menu (M)*

*The "Opening Menu" will appear offering choices:*

* 3: Exit Convergence*

* Status: Abort/Cancel Changes*

* M: Begin Convergence*

* *

* *

*Note: video information must be present to correctly adjust the
convergence. A signal source is required to lock the vertical and
horizontal sync. After entering the "convergence service mode" verify the
presence of a video source by confirming the presence of active audio (use
the volume up function on the remote). Use the channel up and down function
on the remote to select the desired tuning source.*

* *

* *

*Select item "M" from the first menu, the "Convergence Menu" will appear
featuring 5 possible selections.*

*1. green geometry*

*2. red To green Convergence*

* *

* *

*CONVERGENCE TOUCH UP PROCEDURE*

* *

*1. Enter the "convergence service mode" as described above in the
"convergence service mode procedure".*

*2. Select the desired color requiring adjustment. Note: Do not
select Green Geometry (1). This procedure is described under "Major
Convergence/Geometry Alignment. If Green Geometry is altered during this
procedure a "Major Convergence/Geometry Alignment" maybe required. *

*3. Cover the Output Lens of the single color presently NOT being
adjusted. Example: If you select Green to Red Convergence (4) cover the Blue
Output Lens.*

*4. The highlighted adjustment Icon (Cross) should be illuminated on
the middle left side of the screen. Make the necessary Convergence
Adjustments using the following Remote Keys:*

* *

*· Use the Arrow Up ( ) to adjust the selected color up.*

* *

*· Use the Arrow Down Key ( ) to adjust the selected color down.*

* *

*· Use the Arrow Right Key (-) to adjust the selected color to the
right.*

* *

*· Use the Arrow Left Key (+) to adjust the selected color to the
left.*

* *

*5. Move to the next location to be converged. It is not required
that the full Convergence Sequence be followed while performing the
"Convergence Touch Up Alignment Procedure". The following alternate Remote
Keys allow for positioning of the Icon to the desired adjustment location:*

* *

*· Key 2 on the Remote Transmitter will position the Adjustment
Icon upward on the screen.*

* *

*· Key 8 on the Remote Transmitter will position the Adjustment
Icon downward on the screen. *

* *

*· Key 4 on the Remote Transmitter will move the Adjustment Icon
to the Left.*

Transmitter. This forces the corrections to be written to the EEPROM on the
Convergence Module.*

* *

* *

* *

*Note: To save the convergence corrections made above you must exit the
convergence menu by selecting Exit/Save Data (1)*

SOURCE: Warped Picture, Separated colors

You have a convergence problem.  Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors.  Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors,  etc. Everything you need to fix it yourself.

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.

Philips Magnavox 51MP392H Rear Projection Television


are you getting sound, was it moved laterly, did you just get it from somone, did it get wet, does it make clicking noises, was the picture color/ convergence blurring before this, were the colors slowly seperating such as red/blue/green?, did the picture bow on top and bottom or sides prior to tihs, was there anything note worthy prior to the blank screen.

generally its IC convergence problem with the larger philips projection TV's however I need more info on your TV, also size make model # anything you can provide gets us a more narrowed solution.

hope this helps....

Audio only, no picture


Audio without video is usally a vertical or horizontal deflection problem with the DPTV chassis and Mag 1 chassis which is what you have. You may need a new deflection Large signal board. If you would like a link to one of those boards let me know.

Wide black area top of the screen.


More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

NO PICTURE HAS SOUND


When you say small do you mean shrunk up top and bottom as well as from side to side. You definitely have a deflection problem either horizontal or vertical.If the picture just shrunk top and bottom you have a vertical deflection problem. Do you have the service manual for your model? If not let me know and I will email you one. Describe the shrinking issue a little more and I should be able to give you some guidance.
