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 LC-30HV4M _ LC-30HV4X _ SOFTWARE UPGRADE PROCEDURE

SHARP LC-30HV4M _ LC-30HV4X _ SOFTWARE UPGRADE PROCEDURE








UPGRADING INSTALLED PROGRAMS


CAUTON: Exercise great care to hide the procedure in entering the in-process adjustment mode from the customer. Inadvertent setting changes in this mode may cause a fatal error resulting in a program being unrecoverable.
Programs installed in the product are mainly divided into the following two categories:
  • Main programs (for AVC system)
  • Monitoring program (for display)
TOOLS
  1. PC
  2. A Windows 95/98/me/2000/XP PC that has a COM port (RS-232C).
  3. A USB-R232C converter will be acceptable provided that it is appropriately set and has PC compatibility.
  4. RS-232C cross cable.  Interlink cable is also acceptable.
PREPERATIONS

Rewriting a program needs the product to enter the in-process adjustment mode.
  1. The rewriting software is supplied in the form of an exe file named e.g., "MAIN_2002_10_10A.exe" (provisional).  Create a directory on a HD and copy the software into the directory.
  2. Double-click the file. The file will be self-extracted. Check the extracted file against the documentation accompanying with the software.
  3. Connect the AVC System and the display unit with each other and make them ready for operation (make sure the power LEDs of the AVC System and display unit turn red).
  4. Use an RS-232C cable to connect the PC to the AVC System.
  5. Turn off the "MAIN POWER" button of the Display.
  6. Press the "MAIN POWER" button while holding down the "VOL (-)" and "INPUT" buttons on the display unit simultaneously. (Be continuing pushing "VOL (-)" and "INPUT" buttons until a display comes out.).  If blue characters appear on the display, the system has entered the in-process adjustment mode successfully.  If not (the normal activation screen opens), retry.
RE-WRITING THE MAIN PROGRAM
  • In the in-process adjustment mode, press the "CH (Up)" button on the remote controller. You will move to page ("13/13" will appear on the upper left corner of the screen).
  • Make sure CENTER PROG UPDATE on page 1/19 is highlighted.  (It checks that "CENTER PROG UPDATE" on page 1/19 is chosen.)
  • Use the "VOL (+)/(-)" butons to change OFF to ON.
  • Press the "ENTER" button on the remote controller. Characters on the screen will disappear and the screen blacks out.
  • Double-click the batch file specified in the document accompanying with the software.
  • A black window (MS-DOS window) will open and rewriting starts automatically.  For a while, "ok received" will appear on the screen.  Rewiring of the main program is now complete. Unplug the AC cord from the AVC System and turn off the system and then on again.
  • Enter the in-process adjustment mode and make sure the version information on the "CENTER Version", "OSD Version" and "CVIC Version" lines on page 1/19 has been updated.
