I removed the circuit boards from the monitor. No bad caps. Nothing looked out of the ordinary. They all looked fine. I did notice some heat discoloration on the opposite side of the boards but no burning of any circuits. There are a couple chips on one of the boards so I gently pushed them in because I have heard of "chip creep" in the past. I reassambled the monitor and have been using it all day without the problem occuring.
There are 7 connectors from the boards to the monitor. Maybe a loose connection has been reestablished?????

Try it on another PC first, if it is still bad, read on.
When you have strange symptom like this, first thing to look for are the caps (bad caps with bulging tops) inside. Common problem with these Princeton and other brands as well as you can see in my pictures:

The picture screen is green and red.


It sounds like one of the three color guns has failed and based on the fact that you have red and green that would leave the blue gun as the culprit.

The screen is green and the tint option in the menu cannot be adjusted.


This symptom usually indicates CRT failure. Projection TV's, especially older types use 3 CRT "guns" to project the image on the screen. One is Cyan or Red, one is Green and one is Blue. If the Red and Blue become weak or do not project, the Green gun overpowers the output of the other two. These three "guns" are aligned exactly on top of each other so when all three are correctly functioning, the correct colors are projected on the screen.

After turning the tv on the colors are reddish and slow to conform to the normal color tones. i have a 36" toshiba flat screen tv


My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

Philips 30PW850H 30" TV screen is completely


hi,
normally color crt tvs have three guns such as red green and blue. when the voltage at the cathode any of these guns go to zero that color will lead in the screen.

in ur case the green cathode voltage is low. that's why the is green on all over the screen.
if it suddenly came then there is a possibility of dry soldering in the pcb behind the picture tubes neck. we called it as base board. which consist of three transistor or one ic for cotrolling cathode voltage of the guns .

if u have a soldering iron the open ur tv and try to re-solder components in the base board. mainly the component with three leg ( if transistor). if there is ic it will have more than 6 legs . if you can try to re-solder all the points. Be care-full that dot make short circuit when soldering. after care full soldering power on the tv and watch the scree. you problem Will solved.

if u need any further assistance from me, feel free to contact me through fixya.
ok

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

The red, blue, and green are all out of alignment. HELP!


Sounds like the guns are out of alignment. This isn't normally something that a user can adjust.

Has the television been dropped/jarred or moved recently?

If the TV has a manual degauss function, you can try that (assuming it's really a CRT). Otherwise unplug it from the wall for a half hour, then plug it back in and see if anything has changed.
