In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

PANASONIC PT-44LCX65 _ PT-53LCX65 _ PT-61LCX65 _ LAMP REPLACMENT PROCEDURE

PANASONIC PT-44LCX65 _ PT-53LCX65 _ PT-61LCX65  _ LAMP REPLACMENT PROCEDURE



LAMP REPLACEMENT

  • Press the POWER button to turn off the power.
  • Wait for about 1 minute until the cooling fan stops.

Note:  The lamp cooling fan will continue to operate for about 1 minute after the power is turned off. Do not unplug the AC Cord from the outlet until the fan has stopped. Avoid interrupting the power by using circuit breakers or switchable power strips.
  • After the cooling fan has stopped, unplug the AC Cord from the outlet.

Note:  Wait more than one hour before replacing the lamp.

[ Forced cooling function ]

  • If you need to replace the lamp more urgently:   The Projection display has a forced cooling feature.  After the POWER button is turned OFF, and during the first minute of the normal cooling fan operation, press the VOLUME UP button on the unit and CH UP key on the remote at the same time for more than 5 seconds.  The cooling fan operates for about 10 minutes. (LAMP LED will flash 5 times every 5 second and POWER LED will flash red for 10 minutes.)
  •  Remove the Front Cover Unit from the latches.
  • Turn the Knob to the left.
  • Pull the Lamp Cover out.
  • Loosen the Screw on the Lamp. Then, pull the Lamp.  Note: Because the Lamp may still be hot, use caution when handling.
  • Install the new Lamp, and tighten the Screw.
  • Install the Lamp Cover, and turn the Knob to the right.
  • Install the Front Cover Unit.
  • Note:  After replacing the Lamp, use caution to reset the Lamp time.
LAMP TIME RESET PROCEDURE
  • Plug in the AC Cord, and turn on the power by pressing the POWER button.
  • Press and hold the VOLUME DOWN button on the unit and the SPLIT key on the remote together for over 5 seconds in power on condition.
  • When the reset is finished, the display  will show {Lamp time was reset to  ‘0’}; appears and the LAMP LED goes out.
The unit will detect when the Lamp’s end of life is approaching and the following message will be displayed. And the LAMP indicator light will be lit when the Lamp’s end of life is approaching.

Influences of frequent lighting, continuous light use for over 24 hours, the number of times lit, the length of time between lightings, etc. may shorten lamp life. (Because of this, we recommend having a replacement lamp on hand.).
  • The lamp could rupture if dropped and lamp fragments could cause injury.
  • Because the lamp unit is hot immediately after its use, touching it may cause burns.
  • Allow the lamp to cool before handling or replacing the lamp unit.
  • If replacement of the lamp unit becomes necessary during the operation of the Projection Display, follow the procedure to turn off the power and wait until the lamp unit cools completely.
  • Do not disassemble the Lamp.
  • The lamp may be hot. Be careful when handling. Wear gloves.
  • Under no circumstance should you touch the actual bulb.  At this high operating temperature the natural oil on your finger can cause the glass to weaken where touched and the bulb can crack or explode.
