Tools/Supplies:

• Phillips screwdriver (magnetic tip)
• 1/4" nut driver
• 1/4" wrench, small adjustable wrench, or stubby Phillips (to access screw in tight spot)
• Canned air with extender tube, a few cans
• Optical-quality microfiber cloth
• Clean, lint-free cloth
• Small brush

Precautions:

• Do not use any cleaner that contains ammonia. A clean lint-free cloth dampened with water was adequate for me.
• To prevent over spray, do not spray any cleaner directly on to any TV part. Spray on to rag only. (I only used a dampened rag to clean plastic and metal surfaces; no electronics or optical surfaces.)
• Use only an optical quality microfiber cloth and/or canned air to clean the light engine lens, the mirror and the inside surfaces of the front screen.
• Exercise caution using canned air. Do not tilt the can and allow any liquid propellant to escape. I had a few full cans available, and swapped to a new can often.
• Keep screws removed from each panel in a different cup. Most are different sizes.
• When disconnecting wiring connectors, note color codes for connector orientation when reconnecting. Most connectors only install in one orientation, but it's not clearly obvious.
• If contacting any circuit boards/wiring connectors, make sure to touch the metal frame first to discharge any static charge.

Disassembly Instructions:

1. Insure TV is powered off and allowed to cool at least 2 hours (overnight if possible).

2. Open and remove the Lamp Unit door on left side of TV. Using a Phillips screwdriver, loosen the 2 screws on the lamp unit and carefully remove the lamp unit.
Clean lamp unit, using microfiber cloth on the lens and set aside for reinstallation.

3. With the lamp unit removed, you can see the light engine's color wheel through the small hole. I covered this hole with tape to prevent any dust from entering during my cleaning.

4. Remove the lower rear cover (2 screws on each end and 9 along the back panel).

5. Remove the cover from the Input/Output jacks by removing the 7 silver screws securing the cover to the Input/Output modules and sliding the cover off the power cord grommet.

6. Remove the front pedestal cover as follows:
Note the blue, red and grey wire harnesses on the right side leading to the front panel controls, AV-3 jacks and PC slots. Loosen and remove these wires from their wire ties.Grasp the pedestal cover at the ends and gently pull outward. It is installed with quick-release pins and should release easily.Gently pull the pedestal cover out, being careful to guide the wiring.Carefully disconnect the 3 wiring connectors, noting the color code for reconnection.In preparation of removing the front screen, 2 hidden screws must be removed. These 2 screws secure the bottom corners of the front screen and are installed from the back.

7. Remove the plastic housing where the lamp unit was removed:
Loosen the wire tie and remove the wires from the top of the plastic housing (these wires go to the lamp door switch).Remove 2 screws securing plastic housing. One on left side and other in base on right side (with limited space available, will need 1/4" wrench or stubby Phillips).Slowly pull housing from TV, until you can reach the connector to the lamp door switch. Note color code and disconnect wiring connector (may be easier to pull some wire through the hole and lift upward to remove connector).The front panel screw can now be seen in a recessed hole. Loosen this screw. (I did not remove the screw completely, to aid in reinstallation. Otherwise, a magnetic Phillips screwdriver may be needed.)8. From the area of the front panel wiring ties the other hidden front panel screw can be seen in a recessed hole. Loosen this screw.

9. Remove 11 of the 12 screws along the back of the TV securing the front screen, leaving one loosely installed at the top.

10. Remove 4 of the 5 screws on the front of the TV, at the bottom of the screen.

11. While holding the screen at the top and bottom, remove the two remaining screws, and gently lift and pull the front screen panel away from the TV.
Store the front screen assembly where the inside surfaces can be cleaned with the microfiber cloth and/or canned air.

12. Reassemble the TV in the reverse order, remembering to remove the tape from the hole covering color wheel, if installed earlier in step 3.


There are 3 fans to clean:
The large Lamp Fan behind the lamp and light engine assemblies is clearly visible.There are two smaller fans mounted next to each other. One fan is mounted between the cable card slot and the light engine and the other fan is mounted just to the right directly on the light engine assembly. It's somewhat inaccessible without removing the light engine, but using an extender tube on your canned air, it is easily cleaned.
The lens of the light engine will have the most dust. Clean with canned air and the microfiber cloth. Use a corner of the cloth to reach beneath the plastic tabs covering the lens.

The mirror may have a few dust particles. Gently wipe with the microfiber cloth and use canned air. Hope this helps,

Wipe the area with eyeglass polishing cloth if you have it to clear any dirt/dust.
Rub the scratch back and forth with a clean pencil eraser. Avoid using the red kind and you will not have to clean off the red color afterward.

Much like anything in your home, TV screens get dirty with fingerprints and dust and require a periodic cleaning. Keeping your TV screen clean is essential for ensuring a clear picture. However, cleaning the front of your TV is not something that should be left for the cleaning lady. The use of certain cleaning products and solvents can damage the front of your TV screen. Special care must be taken in order to make sure that your TV screen is cleaned properly.
Every kind of TV has different steps for proper cleaning. If you are unsure what kind of TV you own, consult your TV user's manual to ensure that you are using the right cleaning method.

• Direct-View - Older direct view TV's can be cleaned with glass cleaner and a paper towel. Newer tubes that may contain any special coatings, like an anti-glare coating, should be cleaned with a damp cotton cloth. If you are unsure if you have any special coatings, it is best to be safe and use the damp cloth.
  
• CRT Rear-Projection - Before you can begin cleaning, you need to determine if you do, or do not have a screen shield. A screen shield is a hard plastic cover over the front of the TV screen. If you can't tell, give the front of the TV a light tap. Another way to tell is to check for ridges in the screen area. If you can feel ridges on the screen, then you do not have a screen shield. Rear projection TVs without a screen shield require a special kind of cleaner and rag. These are available for purchase at your local TV service center. Those that do have a screen shield should be cleaned with a dry or damp soft cloth. If it's extremely dirty, a mild soap may be used. Do not use paper products, such as paper towels, to clean the screen shield. Paper products GA_googleFillSlot("TL-IMU-Article"); can easily scratch the surface of the shield. Screen shields can have a tendency to streak while cleaning. If this happens, use a dry cloth and buff the screen in a small circular motions.
  
• Microdisplay Rear-Projection - All microdisplay TVs have some sort of screen shield on the front. These TVs should be cleaned with a damp cloth. Microdisplays with a shiny screen shield can be cleaned with a mild soap if extremely dirty. Those with a flat screen shield should not be cleaned with any cleaning agents. Do not use paper products to clean the front of the TV because they could scratch the screen surface.
  
• Plasma - Plasma owners should clean the front of the TV with a soft, damp cloth. The use of a mild soap for heavy cleaning is acceptable. The use of heavy cleaning agents could strip the special coatings on the screen, and paper products can scratch the front of the TV.
  
  
• LCD Flat Panel - Be careful with flat panel LCD TVs! Use a slightly damp soft cloth to clean the LCD screen, then immediately dry with a soft cloth. Do not press hard on the screen during cleaning. Doing so could cause severe damage to the display. Do not use any cleaning solvents, such as glass cleaner or soaps, to clean the LCD screen. Paper products could scratch the front of the screen. If you have a pet or child that rubbed something on the screen that you feel could stain or damage it, contact your local TV service center for assistance.

When dusting the TV cabinets, dust with a damp cloth or a mild cleaner. Paper products can scratch the surface of high-gloss cabinets, so avoid paper products. Heavy cleaners can strip the finish off of TV cabinets over time. When cleaning speaker grilles, dust with a dry cloth. Wet cleaners could stain or damage the grille cloth.

Well I finally had the TV picked up by a Toshiba recommended repair place and they are saying that it is a bad Optical Block, also known as the Light Engine. Total for pick up, parts and repairs is $827.00. This seems ridiculous to me when brand new TVs are so much cheaper now. I don't think I will pay that much to have this one fixed.

she musta used a spray too.... your set is all middled now at 31 great, a manual and the correct code to enter the setup to adj everthing is what you need, and you can start with hue.

make sure them buttons are dry ...might blow a hairdryer across it about 5 times back and forth about 3 inches away... dont want to melt the plastic.

1 either your remote button has pressed or some dust in contact. 2 dust near front panel buttons. 3 problem in sytem control section. 4 memory ic .
