Question about Philips 9P5544C 55" Rear Projection Television

1 Answer

Philips PTV840 55" rear projection TV

I used to have a picture that was clear as a bell and now it's blurry. When doing a diagnostic on the horizontal and vertical lines, I can't get them to line up properly and they are also blurry. Everything else works fine.

Picture blurry reddish tint


I'm sorry to say that these Philips rear projection are on the way out. The problem is that the picture tubes (3) are weak. This is typical for Philips rear projection. And the tubes are hard to find and likely to be unavailable. If you found the three tubes it would not be costwise to install them. It would be better to sink the money in new technology tv such as DLP or LCD or LED.

Tv picture blurry, not clear


The LXI or Sears brand used philips TV's. These sets are known for bad coolant fluid. In between the picture tube and their lenses is a layer of clear coolant. Over time the coolant breaks down and causes the picture to become blurry. This can be a complicated repair involving removal of the picture tubes and lenses. Have a repair shop check it for you. Thanks for using fixya.

Blurry picture


You need to clean the projector lens on the optical engine using a soft cotton or, better yet, a chamois cloth. Also clean the mirror mounted inside the rear cabinet and also the front and rear of the screen itself.
If picture is still blurred then your the optical engine is most probably defective.
