To clarify...the LSUQ0100 will correct the fuzzy spots, but it does not fix the blue dot issue..I just fixed mine with LSUQ0100..fuzzy color blobs are gone, but blue dots still there...oh well. :(

    to follow up on my own comment, I started to dis-assemble the tv to check for problems, and I noticed the bulb (which I replaced 2 years ago) had many little pit marks on the reflector. I will replace the bulb to see if this fixes the blue dot issue, and report back. Btw, the blue dots are different than the color blob, best way I can describe them is as tiny little blue "freckles" all over the screen

    This is the final follow up to this, and I apologize for not posting it sooner. To recap: Some of these TV's have a issue with the controller board that is connected to the 3 lcd screens inside the light engine. The issue is a programming issue that causes "color blobs" on the screen. This CAN be fixed with factory tool LSUQ0100. The tiny blue dots that were on my screen, ended up being the blue LCD was failing, and LSUQ0100 DOES NOT fix that. The only fix for that is to replace the blue LCD, which is quite difficult to find, and inside the very core of the light engine. Most TV repair shops wont even touch it. I ended up finding 52" version of this TV cheap because of external screen damage, I swapped that TV's LCD's, controller board, and prism over to mine. I had to re-use my output lens, as it was different than the 52" version. My TV now works perfectly. The truth is, unless you are willing to tear the tv completely apart, and lucky enough to find the right parts, you TV is junk once the tiny blue freckles start showing up. The blue LCD WILL eventually completely fail. Hopefully this helps some people.

How do I get Netflix off my computer and on to the Apple TV

Depending on your computer, you can use the following:

To Remove many programs, go to Control Panel.
  • On the Start menu, enter Control Panel in the search box and select Control Panel from the results.
  • Select Programs > Programs and Features, and then select the program.
  • To remove the program, select Uninstall or, if that's not available, Change.
  • Follow the directions on the screen
  1. or apps downloaded from the Mac App Store, just go to Launchpad by clicking the icon in the Dock or pinching the thumb and three fingers together on the Trackpad. Find the app you want to remove, hold down its icon until you see it jiggles, then hit the "X" button to delete it.
  2. For apps downloaded from other websites or transferred from discs, on your desktop, click Go > Applications > look for the programs you want to uninstall, drag them to the Trash (or use Command + Del). Then open Trash and hit Empty Trash option. That's it.
  3. Next, clean remnant files and folders. Some programs may have created additional files or folders when you installed them. It's best to clean them as well. To do so, click Go > Library. Here find the items related to these programs and remove them all. Be sure to look up the ~/Library/, ~/Library/Application Support/ and ~/Library/Preferences/ folders.
Note: if you want to remove applications that were installed using the Mac package installers (on a .pkg format), you'll be prompted to enter the user password before they are moved to the Trash.

Put Netflix on Apple TV
  1. Launch the App Store app from your Home screen.
  2. Make sure you're on the Featured tab.
  3. Navigate to an app you want to download.
  4. Click on the app icon.
  5. Click on Get for free (or free with in-app purchase) apps, or the price for paid apps.
  6. Click Buy to confirm.

With Schmidt leaving the apartment, who cleans up? There was that episode, where Schmidt stopped cleaning and it got really trashed. Is Schmidt still coming over and cleaning, or are Nick,Winston, etc,...

Schmidt is most definitely sneaking in to clean. He has major OCD, has been found randomly hanging out in the apartment without the other roommates knowing he was even there, and has a spare key.

Change the plug and clean / replace the filter..
Check to see if there is trash / grass and debri in the gas tank, the trash will clog the fuel line so it won't be able to get gas... If there is trash in the gas tank then you deffinately need to have your carbruetor ran through and cleaned really well... The jets are probably clogged up...

I hope this helps...

Blue dots on my tv screen

The model indicated is a Plasma set and if blue dots in motion (moving) may be either on the MAIN board (processes all signal) or it is even possible to be a problem on the power supply board.

Most likely a shop repair as someone would have to look, order board/s and actually replace them to find which board is bad.

This is the nature of repairs in all Plasma sets.

Only boards are sold and no individual parts.

I have a 2000 suzuki quad lt-a500 dealer cleaned carb now it don't idle and pops out exhaust ran good for 2 weeks think i should change the spark plug?

check the diaphram in the top of the carburetor.
they may have overlooked a small hole in it.

if that's not the case then i would certainly take a look at the carb myself.

the carb may have been cleaned out but still got a little more trash in it from the tank once it was reinstalled.

also drain the tank see if there is water or trash in it.

also check the airbox and the airbox intake boot for water or trash.

it's possible that you have a worn valve stem seal, but normally those only worsen as you ride them more, and you would notice smoke from the exhaust due to oil burning.

also check the intake boot for cracks. ( the one in front of the carburetor
and you could change the spark plug it wont hurt hope this helps John

I have weed eater/poulan 22" push lawn mower. It

Hi goldengear...

Make sure you have installed the blade on the right way, if it is installed upside down then it will "beat" the grass instead of cutting it and make a terrible cut, also make sure the blade is good and sharp.
The rough running may be due to trash in your carburetor, I would advise to clean your carburetor and also check you fuel tank for trash, water,etc. if there is any trash,water,etc in there then you need to also clean the fuel tank.
Do one more thing and check/clean/replace your fuel filter if you have one.
Please take time to rate me

I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.

Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.
