REPAIRING AND NOT THROWING AWAY

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 projector - Sharp XR-30 - XG-F210X – How to initialize the EEPROM


Sharp projector - Sharp XR-30 - XG-F210X – How to initialize the EEPROM – How to adjust the ballast output voltage -  How to replace the lap – How to reset the lamp hour timer
EEPROM initialization
Turn on the power (with the lamp on) and warm up the set for 15 minutes.
Make the following settings. Press S2551 to call the process mode and execute "SS2" on SS menu.
Calling and quitting the process mode with the control keys on this model.
Although it is possible for the process OUT to exit using the process menu, the IN/OUT toggle command is also available considering the existing specification.
1) Calling and quitting
With the menu not displayed, press the "ENTER", "ENTER", "VOL+", "VOL-", "ENTER", "ENTER" and "MENU" keys on the remote control or on the main unit.
2) Others
Press the S2551 process key (toggle) on the main PWB to call and quit the process menu.
NOTE: When adjusting in the process mode, set a signal with a vertical frequency of 60 Hz or no signal. (May not be properly adjusted with other signals.)
Forced disabling of the System-Lock of this model
1) Disabling procedure
With System-Lock input window onscreen, press the "MENU", "ENTER", "ENTER", "MENU", "ENTER", "ENTER" and "MENU" keys, in this order, on the remote controller.
Adjustment of ballast unit output power (lamp power)
Adjustment method
1) Unplug the ballast unit lamp cable of the projector from the lamp and connect the cable to the connecting cord (QCNWKA020WJZZ).
2) Connect the connecting cord (QCNWKA020WJZZ) to the adjustment jig (RUNTZA018WJZZ).
3) Connect TP1 of the adjustment jig (RUNTZA018WJZZ) to the negative terminal of the tester and TP2 to the positive terminal.
4) Turn on the projector.

Adjustment value: 71±0.5V
CAUTION: (1) Caution for electric shock: Do not touch the test points TP1 and TP2 of the adjustment jig when supplying power since a high voltage and large current is applied to them.
(2) Caution for heat: Be careful that the resistance load of the adjustment jig produces a high temperature when supplying power.
(3) Connection of the lamp cable: Check that the lamp cable and connecting cord (QCNWKA020WJZZ) are connected securely.
Poor connection may cause smoking or ignition due to arc discharge.
