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.

LIGHT HOUSING TEMPERATURE
     If the temperature on the surface above the light housing becomes excessive (150 Degree centigrade), a thermal sensor, or breaker will open in the primary and interrupt the AC path to the main power supply.  This will cause the Main power Supply to cease operation and an error code will be exhibited on the power LEDs.  This error code is not shown in the blinking LED error code table but if it occurs, the Green Led will be OFF, and the Red LED will be on for three seconds and off for three seconds, then repeat.  This breaker or sensor works like a conventional circuit breaker.  After it interrupts, the circuit due to excessive temperature, pressing the 'Reset' button located between the incoming leads must reset it.
DMD & EXHAUST TEMPERATURE SHUTDOWNS.
     In addition to lamp enclosure, DMD exhaust temperatures are monitored well.  These temperatures can be viewed by placing the unit in the service mode.  They are labeled Thermo-1 & Thermo-2 on the screen and the temperatures are measured in Celsius.  The normal range for Thermo-1 starts about 28Degree C, and normally increases to about 33DegreeC.  This of course depends to same extent to on the surrounding ambient temperature.  If either of these temperatures should become excessive, the unit will shut down and the LEDs will exhibit the blink code shown in the error code chart labelled 'temperature sensor'.  The unit cannot start again until the temperature condition has been corrected.
