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!

If you have a CONVERGENCE problem and it will not adjust---the two STK-392-150 Chips this set uses need to both be replaced and the set adjusted with the original remote control.

You can, if you are able to do the repair, buy a pair of chips for less than 14 dollars plus shipping on Ebay.

If you cannot do the repair--shop around your area--most shops are going to charge 300 or more for this kind of repair.

When you consider the cost of the parts--if you can do it or know someone who can--you can save the set and a lot of money--This repair can easily be done right in your home in about 1 hour--I know as I have done hundreds of them---did two today.

The chips (with the back off of the set) should be on two metal heat sinks on the board on the far left---they will be facing the front of the set.

All that is required to get at them is to remove all the plugs on that board and the screws that hold it in and tilt it up so the bottom of the board is in view---you unsolder both chips (about 18 pins each) and remove the 2 screws that hold each to a heat sink.

With 2 new chips you put heat sink compound on the back of each--it is a white grease to move heat quickly from the chip to the metal, and solder both chips in----put the board back down and all the plugs back(I usually mark all of them so I know where they go) and turn the set on and see what you have...

Most of the time this repairs the set--go into the customer menu and adjust the convergence and you are ready for another 5-8 years of life---this is the normal lifespan of these chips.

If you need assistance or have questions let me know--I am here to help people.

How to clean behind the screen. there is cobwebs and dirt showing when the tv is on. making a bad picture thanks deb


The safe and easy way to do this is to first unplug the set and then remove the back cover.

Most likely you are seeing spider webs; with the back off I use a swiffer duster with a fairly long handle. Clean the three large black lens you will see with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

With the duster get all the webs and do not apply force for any attached to the inside of the screen.

Common problem and I have seen it many times. It is a good idea to clean the lens on the three tubes once a year--any dust on them will make the picture look somewhat darker and dull.

Hi I have a Sony KP-41DS1U projection TV. There is hair or cobweb that 'floats'on the screen. Can I get access to 'blow' or clear it. Many thanks John


You could unscrew the screen frame from the rear cabinet. You only need to get a bit of a gap to gain access. Then use a flexible cleaning wand to clean those spider flowers out of there.

Spider webs in tv


Easiest way to deal with this is unplug set and remove the back cover. The area inside is fairly open---with a swiffer type duster reach in carefully and remove all the spider webs. Go easy along the inside of the inner screen so you do not scratch it or damage it.

Let me know if you have questions.

COBWEBS DRIVING ME CRAZY INSIDE MY SONY TV HELP!


Easy way to deal with this is to unplug set and remove back cover-----with one of the Swiffer type dusters(there should be plenty of room inside this set) gently reach up and get all the webs out---also a good idea if you do this with a lens cloth or paper towel with windex clean the three large black lens you will see when you remove the cover---they usually need to be cleaned about once a year(if they are dusty the picture will be darker and not a clear)

If this has been helpful give me a vote here.

How do I dust inside the screen of a Rear projection TV?


Unplug tv first Usually you can pop the front screen off the set. There may be two hidden catches depending on the model. You may want to use two people for this. Once the screen is off removed the spider web and clean the back mirror with some windex, don't clean the inside of screen with any cleaner. Replace carefully the screen making sure it clicks back correctly
