Try checking some of the tunning and coupling capacitors around the horizontal section as well for some crystalized solder joints in that area.

SOURCE: rear projector tv rear blue projector wont focus

Look into the top of the tube. Probably has fungus growth. Do a search. I posted that solution many times this week for that. Normally, focus don't go out on T.V's by themself. Either the tube is bad or has fungus or the screen control is bad.....but very rare will focus part fail...usually brightness/screen is at fault. Don't forget to check the green tube as well when looking. Take the back off and see if your head will fit. If not, a large mirror will do just fine. Put something on with writing displayed....easier to tell that way.

SOURCE: cleaning cobwebs from philips rear projection tv model 51PW9363/1

I had the exact same problem and the fix is easy to do. Unplug the TV first of all and wheel it out so you can easily get to all of the rear screws.

  1. Remove the screws from the ventilated back panel (the piece of wood with a bunch of holes in it surrounding the AV connection panel.
  2. Remove the wood panel you just unscrewed.
  3. Remove all screws from the upper plastic case on the back.
  4. Remove the back plastic case carefully. This is a little tricky due to two metal pins that it hangs on. Lift it upwards and you should be able to free it from these pins
  5. At this point you should be able to see the entire workings of the TV, and consequently the massive amount of dust that has accumulated.
  6. Carefully take a vacuum and remove all the cobwebs, taking care not to bump the mirror or the lenses.
  7. First, I used some compressed air to clean off the lenses and then used a clean microfiber towel to remove all the dust from the lenses, the mirror, and the screen on the inside. Make sure the part you are wiping the mirror and lenses off with is free from any dust or dirt or you will risk scratching them.
  8. Reverse the dissasembly process to put the case back together.
  9. I went through the convergance settings at this point and found that they were all out of calibration and as such recalibrated them. Use the mulitpoint calibration for best results.
  10. Enjoy a much cleaner brighter TV!

OK if the Fuses go so do the drive transistors, you will have to replace them, trace out to them, and replace, check them out, probably open circuit.

Go there download the schematic, actually a service manual for your TV, it's in a zip, format and it is a PDF inside.

Picture shrinks to only show top half


This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video. You can get complete parts and instructions from www.TvRepairKits.com

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.
