Tools/Equipment.
• Phillips screwdriver (magnetic tip)
• 1/4 inch nut driver
• 1/4 inch 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
Cautions
• Do not use cleaner that contains ammonia. A clean lint-free cloth dampened with water can work.
• To prevent overspray, do not spray cleaner directly on any TV part. Spray on rag ONLY! (Try a damp 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.
• Be careful with canned air. Do not tilt the can and allow any liquid propellant to escape. You may need to swap to a new can often.
• Keep removed screws, from each panel, separated. Most are different sizes. Use separate bowls or trays to keep them from mixing.
• Keep track of color codes when disconnecting wiring connectors so you know what to reconnect. Most connectors only install in one orientation, but is not clearly obvious.
• If contacting any circuit boards/wiring connectors, make sure to touch the metal frame first to discharge any static charge.
Cleaning Steps
Toshiba 52HM95 Rear Cover Removal
1. Be sure the TV is powered off and let it cool at least 2 hours (overnight is ideal).

2. Open and remove the Lamp Unit door (it is on left side of the TV). With a Phillips screwdriver, loosen the 2 screws on the lamp unit. Carefully remove the lamp unit.
Clean the lamp unit lens with a microfiber cloth. Once finished, set it aside for reinstallation.
3. Removing the lamp unit exposes the light engine’s color wheel through the small hole. To block any dust from entering, put tape over the small hole.
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.
Before 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. Hold the screen at the top and bottom AND remove the two remaining screws, AND gently lift and pull the front screen panel away from the TV.
Store the front screen assembly to clean the inside surfaces with the microfiber cloth and/or canned air.
12. Reassemble the TV in the reverse order. Remember to remove the tape from the hole covering the 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 light engine lens has the most dust. Clean using 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 using the microfiber cloth and then use the canned air.

wondering if the screen shown on the TV at the time of this photo of the menu page for your DVD jukebox? We have the same jukebox that is listed and we can’t get the menu to come up looking like that? We purchased the item from experience with a friend’s and we were expecting that menu and we are unable to view in that mode? Any advice would be great! Thanks
