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.

SHARP XR-10X-L - XR-10S-L - XG-MB50X-L - HOW TO REPLACE LAMP - TIMER RESET

SHARP XR-10X-L - XR-10S-L - XG-MB50X-L - HOW TO REPLACE LAMP - TIMER RESET

HOW TO REPLACE LAMP
[Applicable to Sharp DLP projectors - XR-10X-L - XR-10S-L - XG-MB50X-L - XR-11XC-L - XR-HB007X-L]
 This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp failure can be attributed to numerous sources such as: excessive shock, improper cooling, surface scratches or deterioration of the lamp due to a lapse of usage time.  The period of time up to failure largely varies depending on the individual lamp and/or the condition and the frequency of use. It is important to note that failure can often result in the bulb cracking. 
  When the lamp replacement indicator and on-screen display icon are illuminated, it is recommended that the lamp be replaced with a new one immediately, even if the lamp appears to be operating normally.
Should the lamp break, there is also a possibility that glass particles may spread inside of the projector. In such a case, it is recommended you contact your nearest Sharp Authorized Projector Dealer or Service Center to assure safe operation.
  Should the lamp break, the glass particles may spread inside the lamp cage or gas contained in the lamp may be vented into the room from the exhaust vent. Because the gas in this lamp includes mercury, ventilate the room well if the lamp breaks and avoid all exposure to the released gas. In case of exposure to the gas, consult a doctor as soon as possible.
Replacing the Lamp
  Make sure that you remove the lamp unit by the handle. Do not touch the glass surface of the lamp unit or the inside of the projector.
To avoid injury to yourself and damage to the lamp, make sure you carefully follow the steps below.
Do not loosen other screws except for the lamp unit cover and lamp unit.
  • Press STANDBY/ON on the projector or STANDBY on the remote control to put the projector into standby mode.  Wait until the cooling fan stops.
  • Disconnect the power cord.  Unplug the power cord from the AC socket.  Leave the lamp until it has fully cooled down (about 1 hour).
Remove the lamp unit cover.

Then tighten the user service screw to secure the lamp unit cover.  If the lamp unit and lamp unit cover are not correctly installed, the power will not turn on, even if the power cord is connected to the projector.
Resetting the Lamp Timer
Reset the lamp timer after replacing the lamp.  Make sure to reset the lamp timer only when replacing the lamp. If you reset the lamp timer and continue to use the same lamp, this may cause the lamp to become damaged or explode.
Connect the power cord.  Plug the power cord into the AC socket of the projector.
Reset the lamp timer.
