Question about Philips 46PP9302 46" Rear Projection Television

Philips 46 Rear Projection convergence off on part of the screen

I replaced the IC chips on a Philips 46. Convergence was good but I had the cloudy/fuzzy issue so I swapped out coolant in all the tubes. Everything went pretty smoothly. I pulled each one out individually, drained and refilled per the instructions. Once done I powered on the TV and started working the manual convergence. The red was way off and a bit crooked. I noticed that the coolant and lens assembly was a bit crooked when put back together. So I took the Red assembly back out and corrected this. Still slightly crooked on the convergence lines. The biggest problem is that Red alligns in the middle of the screen and has a nice picture. On the upper left side, it is way off. I had a DVD in and Paused. The PAUSED was split, with Red being a couple of inches off. The middle of the screen is aligned. Any ideas? Did I do something to the Red assembly during install? Can this be fixed easily?

    Thanks for the response. Are these alignment rings something I can turn while the power is applied to try to realign?

You may have bumped the alignment rings on the convergence yoke on the red tube while doing the coolant as that could cause the symptom youre describing.

    yes , you have to be careful not to touch any circuit board, but if you adjust them from the front access panel behind the front speaker grille. just turn the little fingers that extend out, but do it gradually as a little movement goes along way. They should be marked with a line of white paint where the origional position was so you may just need to line the line back up on the rings.

Sounds like your convergence chips are shorted which would make the set shut down. Its also possible that the flyback has failed but because the first symptom was the 3d look I would start with the convergence repair.

Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.
No audio or video - typicaly occurs after having the distorted color problems listed above.
