Tv is yellow orange color what is problem


The model indicated does not have a "bulb" as it uses 3 picture tubes.

Examine the picture with color set at zero---stand back and look= if the screen has a mostly yellow (all or part of the screen) you have bad Glycol in the blue picture tube(if need explanation ask) and a look in the lens of the Blue tube will confirm this.

If able with back off and a small mirror look in each lens--red picture, green picture and blue picture.

If the Blue looks like a floodlight with little or no image--bad glycol in that tube.

Is the picuture tube messed up when you see double people and the color is faded


That usually means your convergence ics are going out. Replacing those will get rid of the double imageing. If the color is faded realy bad that means your tubes are going bad. That repair is pretty costly. Tvs over ten years are usually money pits.

Screen is red and I cannot adjust it enough to get the red out


Problem is going to be in the Green and Blue Tube ,you need to change the Coolant Fuild out and out in New,Philips is well known for having Bad Coolant fuild in the G/B Tubes.
With Back Off and TV on Look down inside of each Tube you should be able to see a Clear picture, in each Tube, If you do Not then you need to change out the coolant fuild.
You also have a Screen/Focus Control Block, it controls the Screen Drive and Focus to Each Tube R/G/B 3 controls on top and 3 below them. Top 3 should be for Focuse and Bottom 3 Screen Drive /Brightness to each Tube.
Now in order to aline for Correct Color you will need to adjust all 3 Tubes , Turn Color OFF in Menu then aline the Tubes untill you have a Black and white Picture ,Then go back to menu and turn Color on.

I have color bleeding or washout in solid colors? does that mean the lamp is going bad?


I am not sure which set you have, but, when colors are bleeding on a projection set that is a good indication that the tube is going bad. The color that is dominate, red, green or blue, this will tend to bleed across the screen. If I had more information on your set I could give you a better suggestion, but if it is a tube it will be a costly repair.


I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Color change.


philips is notorious for bad picture tubes. especially the blue. occasionally the coolant leaks out of a tube but this usually causes bigger problems than color change cause it shorts out whatever it leaks onto.

Mitsubishi Diamond Series T.V.


When a tv (Rear proyection) shows this coloration is the meanning that the red color is not there (the red color is generated by a red CRT). Now it can be really bad not having the tube working but before conclution make sure of this: (and if the red color gets back then the tube is ok)
  • is this condition the same in all inputs? or the picture looks ok with a different video source (VCR, DVD other)
  • are the menu letters same as the picture looks or are they fine?
If we cannot see any red color back with this testing, still chances that a technician find an electronic problem that make the tube to be off. so don't rush conclusions and get to the end to save the tv with out replacing the red tube, but if all was done and nothing then the tv needs the tube replacing.

When ever a tube starts to short or is shorted set always will have over bearing drive lines then shut down like RED if it was bad, set would come on long enough for red lines across set then shut down this is the same with all 3 tubes.Also if you think it might be green tube disconnected green CRT board on neck of green tube if set comes on and plays then it is green tube do all 3 tube this way one at a time this will tell you if you have other problems.
