Use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Fixing the picture in my Philips rear projection tv


As far as mostly red--turn color to zero and examine screen--if not gray or black and white it may need the screen controls adjusted.

Dark---with back cover off clean the three lens this model has--they are the light source for your picture and if dusty picture will be darker and somewhat dull looking.

Answer is based on brand/model number listed here.

Hello, My picture has gotten very dim and dark. I was told my bulbs need cleaning. How can I do this by myself or do I have to hire someone to do this for me. Thank you, Debbie


Its more likely that the CRT coolant needs replacement. Thats vert famous for that model. The CRT coolant gets messed up and the CRTs cant project the image properly so it gets a dull picture and the color tints are wrong.

I have a 50in philips plasma tv it will not turn on it flashes 6 slow red lights and 3 fast red lights .I have unpluged it to reset it and it does the same thing .


Hi .

Replace all the electrilitic caps in the power supply.
To nconfirm this grab your hairdryer and blow hot air on the power supply board.
What this does is heats the electolytics and makes them come good.
This step is to confirm the problem.

Rca projection p46812bl not bright enough!


I would think that the black level and the contrast should be all the way up not down the black level is your brigthness . if lhese are all the way up you might try adjusting the screen controls inside the tv if you know how.

Streaking inside of screen


Philips screens tend to be very tough to remove as if you are not careful on removal of the screen frame bolts then the whole screen will come falling off.
