Depending on what type of screen you TV has, many have plastic frenel screens that react to certain cleaners such as ammonia and alchohol based. These compounds can permanently damage the screen causing a cloudy area where it was sprayed. Unfortunately nothing can be done except to replace the screen.

57h94 hd tv,need to clean picture tube


Hello, first you have to uplug the tv, then remove the speaker grill (I think that one just pulls off the front, but some models had 2 screws on each side on the rear edge of the cabinet) once the grill is removed you will see either 4 or 6 phillips head screws along the bottom of the screen frame, remove them and unplug the control panel plug (may be 2 plugs). when that is done raise the screen assembly straight upwards about 2or 3 inches and pull straight out and carefully set aside. Use a quality glass cleaner and a lint free towel's, spray the towel with the cleaner and wipe the lens of the 3 crt's that face the mirror and dry them with a clean towel. Then clean the mirror the same way, do not spray the mirror with the cleaner. when everything is clean, replace the screen by holding it against the front of the set but about 3 inches above the top, press it gently inward on the frame as you press it downward until it is flush with the top of the cabinet, check to make sure it is flush with the sides of the cabinet all the way down, if not re-raise the screen and lower it making sure that it's flush on both sides. Re-plug the control panel , and re-install the screws and the speaker cover,,,,,tks

Cleaning lenses on projection tv


Have the set unplugged please.

CAN BE DONE FROM REAR--from the front is a bit tricky and dangerous---from rear with rear cover removed locate the three large black lens( hard to miss them) and clean them with a lens cloth or a paper towel with glass cleaner sprayed on it.

Depending on how much dust===should be done one time a year.

How do I take the front screen off my TV to clean dust off


If the model number indicated here is correct do not remove the screen---usually all that is required is to remove the back cover (picture is darker and somewhat dull looking?) and locate the three large black lens at top of chassis---they are the light source for this model---clean with a lens cloth or a paper towel with glass cleaner sprayed on it.

The set (again based on the model number) may have a mirror in the rear upper part but it rarely requires cleaning.

Let me know if questions.

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...



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,

My child sprayed something on the screen of the tv and now it has a huge black spot in the corner of the tv. I was wondring if there was a way that you can take off the front screen to wipe it out.


Yes the screens do come off so you can clean in between the layers. But a service manual is reccommended to remove the assembly. But I will post the proceedure below for you.slinteriors_8.jpgslinteriors_9.jpg

Tv is displaying to clean air filter, where is the air filter? How do you clean it? Does it have a reset?


Found on the net:

The Panasonic air filter is located BEHIND the removable Front Panel.....it pops off and you should see it located in a "screwed in" panel.

But, it MAY be located on the BACK or side.....LOOK for a Grille with a grey or black foam piece. IF you don't find it behind or beside the TV, then pull off the Front panel.

Now, those foam filters can be removed from the grille-plate to be washed......the best way to wash it is to PUSH the dust out of the filter by turning the Clean-side of the filter TOWARDs your water source (the faucet or the Much-preferred Kitchen Sprayer)....Now get that DUST OUT!
Once finished cleaning just shake all the water out of the foam panel. Snap it just like you're snapping somebody with a towel. Still Moist? Don't worry, the plenum on the TV is pretty long and "moisturized air" won't hurt the bulb......

Reassemble it......

And DO NOT let that filter go that long between Cleanings!! It EXTENDS the life of the bulb when maintained regularly.

We have blue lines or arches on the bottom and top of our screen of our Panasonic 53" hdtv 1080i Cinema Vision 2003.


if you are handy with screw driver i suggest you remove all cd,dvd or anything you got on top of the unit and remove the back panel from this tv after you unplug the unit of course .first thing you want to do is clean your lenses most time dirt ,bugs,etc and other materials get logged on the lenses also make sure you dont spray directly any cleaning product on the lens make sure you spray a rag or some sort of cleaning towel.
after you finished doing this clean the front panel as well were screen is also clean the silver board thats in there as well.after you finish all of this replace all of the screws and boards back on and give it little while to dry off .turn it on see if u still have the lines if you do then your problem lies in the lenses they might be cracked.
if there not you might have bad electrode or power diode going bad.
