I have an 60PP9202 Rear projection HD TV and the inside of it needs dusting. Is there any instructions available on how to do this? The unit was purchased in 2004 and was vaccumed several times on the back...

You will need to remove the back cover. Here you will dust the lens with a pressure can of air only. Then you proceed to clean the lens with an eye glass damp cloth Get these from an eye doc). As for the mirror, you must use real caution. This mirror is made of a stretched plastic. The best way to clean this is to use a new feather duster. Do not even think of using anything wet to clean this mirror. It is very fragile. Let me add, that you want to do this from the rear also. Next, I would not recommend you try to pull the front cover (screen) off. It would be next to impossible to put the screen back on the TV. You will also feather dust the inside of the screen from the rear. No wetting solution here. Be sure your TV is not plugged in. Thanks for asking and show all hands of support!

My hitachi tv keep turning off after 5 minuted of

I just got done putting my panasonic 50 projection back together. There is a thermal cut off relay on top of your bulb box, can normally be seen after removing the back of the tv. With the tv unplugged make sure the area around this relay is clean of dust. If the simple fix dosn't work make sure your cooling fan is coming on with the tv.

TV shuts down due to air flow being blocked

They had some stupid problems with these sets---If you know how to remove the lamp---it is customer replaceable--take it out and examine it. Shut set off first and wait a few minutes for the lamp fan to turn off. Unplug set and locate and remove lamp. Some of these sets had a lamp (it is in a cartridge like a box) that they covered openings on the housing with a screen like material (like window screen). One side of the lamp has a fairly small narrow strip of this and it blocks up with dust from the fan which is trying to keep it cool---if the screen is blocked up you will see it; Do not touch the face of the lamp when you handle it--if you find yours has a screen like material--clean it off with a brush and put it back--the later replacement version of this lamp has a screen that is coarse and does not block up with dust---on a couple of these I removed the blocked up screen material until I could get the newer lamp so the customer could continue to use it--if cleaning the dirt off works you may have to do it from time to time--depends on environment--the fan tends to pull dust and such out of the air and right into the lamp---

I do this for free here so if this does help you give me a vote here. If you have questions or need help contact me here.

I went to the code section it appears I need service . The code says red lamp indicator blinks ever 5 sec. turn on tv.serval times if that fails call a service person. Do you have any solutions? I am a...

try unplugging it first and let it set for a minute or two, plug it back in and try it again. if it keeps doing this try cleaning it out take out the front cover pull the bulb out, use a rag and shop vac. then take off the rear housing and left speaker then clean that out, baically the dust is keeping the heat in wich creates an overload. then put it back together. if that doesn't work it's the ballast then i recomend buying a new tv you could find an awesome tv for the same price as that ballast. and i know it won't be a 50" but you'll be happier in the long run.........

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!

Mitsubishi WD-62827---PICTURE TURNS GREEN

I had the same problem. I deducted that if my TV worked fine for an hour or so and then the colors became bad (green, people's faces purple...), it must be a overheating problem. Simple logic, right? So, I picked up a few tools and a small vaccum and went to work.
I went first for the main source of heat: The lamp. Just a few screws, and I removed it. The lamp cage has a fine screen to prevent the dust to cover the lamp. Mine was covered with dust! And the fan behind the lamp was also covered with dust! Bingo!!! That's my problem! I cleaned everything and vaccumed all the air vents on the the back of the TV. I put the lamp back and checked that the fan was working. The TV works like new since!
Before you are out of a TV for days and spend an arm and a leg for a "Technician" to fix it (replacing expensive parts that didn't need to be replaced in the first place), try what I described above first. It's very simple and it takes only 15 minutes.
Since my TV is 2 1/2 years old, I purchased a replacement lamp. I know that one of these days it will burn out. I'll be ready and my TV will be working again in 15 minutes!
Since my problem was solved, I didn't go to the next step. There must be one or two other cooling fans inside the TV, but they must be working...
Good luck,
