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.

Abnormal detection distinction at DEMO indicator (LED_red)

It has a case that need to Power OFF immediately after detected an abnormal condition without display any error indication due to safety matter. In such case, a trouble point can be judged by a distinction indication at DEMO indicator which current is being supplied during Power off.
Basically, it is decided to be distinguished which input port of the system microcomputer was detected or which communication information was detected. Moreover, two kinds of over-voltage and drop-voltage are decided to be distinguished, and contents of indication are decided to be changed when it is detected in the range of the A/D value in the A/D input port, for example the over-voltage, the normality voltage, the drop-voltage of the power supply line are being monitored.

DEMO indicator Distinction Display Format

A lighting period (or flashing period) and a lights-off period are controlled as the bottom figure after the abnormal detection and the Power off transition. It will repeat and control 1 frame of the bottom figure. (A lighting period or flash period is mentioned on the "H" side.) 1 frame is set up as 2 sec lighting period in every 3 sec or flashing period, repeat m time, and then the last period only (m+1) should turn off the lights. (To recognize the head position.)

m is 2 m 10, it can be set up in every model freely as long as "‘Distinction No.’ and the Abnormal Detection Table” mentioned in two clauses are protected.

A flashing period is set to one place only of No. 1 - No. m, and others are lighting period. The ‘Error Distinction No.’ is made at which part is flashing. In other words, it is set as the ‘Distinction No.’ by looking at which number is flashing from the head of 1 frame.

Note: It can set up freely in every model the repetition period 3sec, the lighting or flash period 2sec, a flashing periodic 500ms etc. as long as it can be recognized.
