The tv on;y shows a small pip window in color if it is a large picture the picture is in black and white how to fix?

Whatever input video signal you're using, PIP should be in color. What are you using out of your dvd for the second video input source, composite or component? Composite you should always have color, Component, if you have a bad red or blue, and just the green is working, you will get black and white. The green is the luminence signal.

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.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the's something else..don't know you?

Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here

Blurry and colors are seperated red green white

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .

Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!

Red , Green And Blue.

Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.

The focus controls on this set are in the front behind the bezel. I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set. The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment. Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control. Facing the set, Red is left, Green is middle and Blue is on the right. Use only one hand inside an operating television. Do not touch the board, just the controls. This concludes television alignment 101. Any questions respond to this post and I'll reply.
