Re: what screw do i actually loosen to remove the lamp in...

There should be 2-sets of screw for one panel and another panel with 1 screw. Unscrew the single screw. There will be another single screw that hold the bulb. Loosen that one and pulled the bulb out. Hope that helps.

I am 99% sure I have a bad fan. TV was turning off (probably overheating). We replaced the lamp (for the fourth time), but the fan continues loudly when the set is turned on. Question-- Can I replace...


• 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


• 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,

How do I replace lamp in my Sony-KDF42WE655 model.

There are 2 thumb screws at each lower side. Fully loosen those thumb screws then pry the panel out. You will see the lamp covered by a plastic panel. You will see 4 screws covered by gray plastic. Remove the screws and you will see another thumb screw in it. Just loosen the thumb screw also then remove the covered plastic. You will now see the bulb. You need to remove the 2 screws then you can now remove the bulb. Just do backwards to put everything back again.

Whow to replace lamp on tv sony kdf-e60a20

Follow this procedure to replace the lamp:

1. Turn off the power on the main unit. Wait several minutes, then unplug
the power cord.
(The cooling fan will continue to operate for about two minutes after
turning the power off.)

2. Wait at least 30 minutes after unplugging the power cord to allow the
lamp to cool down before replacing it. To avoid being burned, do not
touch the lamp receptacle once the lamp has been removed.

3. Take the new lamp out of the box.
Do not touch the glass portion of the new lamp.

✍ Do not shake the lamp. Vibration can damage the lamp or shorten
its life.
✍ Avoid touching the front glass of a new lamp or the glass of the
lamp receptacle. This may reduce picture quality or lamp life.

4. Loosen the screws on the rear side panel.

5. Remove the front panel.

6. Pull out the lamp.
Loosen the right screw on the cover with a coin or similar object.

Remove the screw from the lamp cover. Pull down the cover toward you.


Unscrew the lamp and pull out the lamp horizontally.


✍ The lamp is very hot immediately after use. Never touch the glass
portion of the lamp or the surrounding parts.
✍ After it has cooled, place the used lamp into the empty box of the
replacement lamp. Never put the used lamp into a plastic bag.

7. Place the new lamp into its place, then tighten the screw.
Mount the new lamp securely. Failure to mount correctly may cause a
fire or the screen to go dark.


Push the cover back on. Make sure that the hole on the cover aligns with
the hole on the unit. Reattach the lamp cover by tightening the screw.


✍ If the lamp cover screw is inserted incorrectly, the lamp may not
operate properly. In such a case, remove the screw, insert it
correctly and then tighten the screw completely
✍ If the lamp cover is not reattached securely, the self-diagnostic
function may be triggered and the POWER indicator flashes three

Loosen the two thumb screws at each end of the lower front panel where the power switch is until you feel it disengaged. Pry the panel, don't be scared that you might break it, it's just held by two expanding cylindrical retainers, set aside. The lamp is covered by the grey plastic panel on the left that has a thumb screw which in turn is also held by another grey plastic panel with four phillips screws. Remove screws and loosen the thumb screw. Remove the grey panels. The lamp is on the left and held by two shiny allen driven screws, loosen screws with an allen wrench then pull out the lamp housin

My picture is dark and have changed the brightness

This model is notorious for needing a new lamp about every 2 years. The lamp is accessed through the front by removing the long plastic cover under the screen (it just pulls off). Under that, to the left of center, is a square cover with one grey plastic screw. Loosen the screw and pull the lamp assembly out. It should just slide right out. Turn it around and look at the lamp. If the lamp face or reflector looks "cloudy" or "misty". Replace the lamp with Philips part number TY-LA1000. Just Google the number and you will find them available for around $100

Can't remove screw on lamp cover panel PT-43LC14

Using a phillips head screw driver, you need to grip the unit with your left hand and then push really hard against the screw head before starting to turn the screw. They are very tight from the factory. Once it breaks loose and starts to unscrew, the rest is easy.

Location of the lamp enclosure

Pull off the front silver panel ... it is about 3' long and about 4" wide. It pulls off easily. below this panel on your left side you will see a small black panel held in when one Phillips screw. Remove this screw and the panel will slide to your left. This exposes the lamp unit which in turn is fastened with one brass coloured screw. Loosen this screw (screw stays attached to the lamp housing) and then simply pull the lamp unit forward to remove. Word of caution ... do not remove if the lamp is hot ... wait until it cools down. This procedure sound difficult but is really quite simple. I have replaced my lamp on twice already.
