Well, I have a 57HM167. I bought a 65HM167 for $100 because it had a blown bulb. The TV was disgusting when I picked it up. I had never seen so much dust on a TV. I bought it because I made my HT cabinet to fit a 65-67" DLP. I ordered a new Toshiba bulb from Mwave for $110 shipped. I eagerly awaited the new bulb to get so I could watch this beauty. I put a brand new bulb into this 65HM167 with about 10,000 hours of total TV time and come to find out the picture looks like garbage! The whole set is washed out white. There was no clear definition on HD content. The colors were dull. The blacks were gray. I was bummed to say the least. I found out it wasn't the bulbs fault. The real answer awaited.
I decided to pop open the TV and take a look myself. There is a total of 10 screws that bolt down the face of the TV to the frame. 6 are around the upper portion of the screen bezel. There are two around the back of the lower right and left corners of the TV. Then there are 2 screws behind the screen mesh front light indicator housing. See the screw locations below.
After the screws are loose you need to lift the front screen and bezel up towards the ceiling. The screen is now able to lift away and off the TV chassis.
You are now exposed to the main mirror and the eye lens.
I instantly knew what my problem was, the eye was disgusting! Now wonder the whites were washed and the color was dimmed.
I used a specific screen cleaner from Office Depot that was designed for things like this. I used a clean terry cloth.
This shows how gross the lens was during the middle of cleaning.
Here is the lens all cleaned up and ready to rock.
I also installed a new bulb and cleaned the rear screen surface and main mirror while I had everything open.
I cant tell you how much I love the 65" over the 55". Check it out for yourself!
The picture is now AMAZING! Total time took about 20 to 30 minutes.
