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.

EXT OPTION Menu and Functions
FAN FULLMODE
Setting the cooling fan motor rotation speed.
Switching ON "FAN FULLMODE", the rotation level of the fan becomes high-speed rotation (fixed). Moreover, when "FAN FULLMODE" is ON, changing "HIGH ALTITUDE MODE" in OPTION menu becomes impossible (setting FAN FULLMODE is given priority more than HIGH ALTITUDE MODE).
AUTO SETUP
Setting AUTO SETUP mode.
- NORMAL: Dot clock is adjusted strictly.
- SPECIAL: Dot clock is adjusted roughly.
# Do not usually change initial setting (NORMAL)
SELF CHECK
(1) - Software Version (MM : Main microprocessor, F:FPGA )
# FPGA (Field Programmable Gate Array)
(2) - Input signal Display ( [NO-SYNC] is displayed when there is no input signal).
(3) - Input Horizontal/Vertical signal frequency (For the RGB/YPBPR Input only)
(4) - The temperature abnormality check ("NG" is displayed for any abnormality)
(5) - Temperature around the air intake port/exhaust port and Filter sensor (deg C/A/D conversion value)
(6) - Filter sensor Difference Correction (A/D conversion) Value
(7) - Rotation check of Intake fan / Lamp fan / Iris fan (Displays "NG" when Fan is abnormal condition)
(8) - Iris condition check (Abnormal condition = "NG")
(9) - Lamp condition check (Abnormal condition = "NG")
(10) - Lamp cover installation check (Abnormal condition="NG")
(11) - Displays the projector cumulative usage time
