My philips 55pw9363 has yellow tint I took off the back the blue bulb has no pic in it like the other two but light is bright

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

yes you can change the blue crt,but are pricey.usually they look like craters on the moon when you look into it when turned on.its only the blue tube that seems to fail for some reason....hope this helps,steve.
ps.think its phospur burn

These sets have several common problems listed below.

Problem #1) Convergence

• Screen may look distorted
• No Audio/Video - makes a chirping sound.

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking screen
• White looking sceen
• Halos around objects
• Red/Orange looking

You can see some examples and find a fix here...

That could be either the coolant is needing replacement or the ICs have failed can you post a pic of the screen and I can diagnose correctly

You may have 1 of two problems.

1) Convergence Chips are failing - Using your original remote goto the "convergence" screen. 

Try to adjust the red - UP - DOWN - LEFT - RIGHT

Next try to adjust the blue - UP - DOWN - LEFT - RIGHT

If you can move both colors in all directions you do not have a convergence issue. 

If you can't move one or more colors in one or more directions the convergence chips are defective and need to be replaced. 

If your convergence chips test out ok the most likely problem is......

2) CRT Coolant is cloudy  - The bright outline you described is one common symptom. Other symptoms include dull images, red or orange tint, halo around images.   

If you goto the site www.TvRepairKits.com - and click on "Tips" - you will find more detailed instructions on how to check the convergence.  

im assumiong you checked the tint in the menu options. if not go check it. other wise it sounds like you have a weak tube, or you do not know how to adjust the screen brightness. this is how i adjust the brightness (you dont need to touch the focus). turn the red up until your whole screen is tinted red, then do the same with the blue and the green. then go through each one and turn down just a little till your pic darkens a little. good luck

cleaning the CRT lenses and mirror will help, however with that model I would suspect that the gree and blue CRT needs the coolanr changed to get a your color and clarity back. thats a common problem with all phillips rear projection TVs

I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.

The bulb won't do that. What you're describing sounds like a light tunnel failure.

Phillips have been known for the coolant to get contaminated especially in the blue CRT. it congeals and your picture will become hazy and out of focus.This is something you an do yourself. If youre careful. If you would like instructions on how to do this proceedure. Let me know.
