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.

RF20 UNIVERSAL REMOTE CONTROL - HOW TO PROGRAM - LEARNING FUNCTION

RF20 UNIVERSAL REMOTE CONTROL - HOW TO PROGRAM - LEARNING FUNCTION


PROGRAMMING PROCEDURE & LEARNING METHOD

Pre-Programmed Code Method
The pre-programmed 3-digit codes are given by next post here. The codes are listed by Component category (i.e., TV, VCR, DVD, etc.), then by brand name. For instance, if you want to locate a code for a Sony TV, first locate the TV category, and then look for the Sony brand.  Once you have located the 3-digit code (or in some cases, several code numbers) for the Component that you want to operate with your RF20, write them ALL down on a piece of note paper. It’s important that you write down all the codes because only one code is going to work for you.
2. Now, turn on the Component you want to program... let’s say your TV to start. Look up your TV’s manufacturer set-up code from your reference list.
3. Press and hold the MAIN and ENT (Enter) buttons at the same time for approximately 3 seconds, until the word “SET-UP” is displayed at the top of the LCD screen. This signals that you are now in set-up mode. { You now have 30 seconds to perform the next step while you are in SET-UP mode. If you don’t press a button within 30 seconds, SET-UP will disappear from the screen, signalling that you have exited set-up mode and you will need to start over.}
4. Press the P-PRO display button to select the Pre-Programmed Method.  The screen will then display the five Components from Page 1 of the MAIN menu.  To display Page 2 of the MAIN menu that lists an additional five Components, simply press the PAGE▲/▼  buttons.
5. Press the Component display button you want to program.  For example: If you want to set-up the TV Component button, press the TV Component display button. The display at the bottom of the LCD screen will flash “FROM - TABLE”.

6. In this step you verify the type of component you plan to operate with this component button. For example: If you plan to operate the TV component with the TV button, simply press the TV display button once again. However, if for example you are setting up AUX to operate a second DVD Player, you would first need to press AUX in Step 5, and then DVD in Step 6. {If the Component fails to turn off after you have entered all the code numbers listed for your brand, you can scan through all the other code numbers that are pre-loaded into the RF20 for that Component (in this case TV) by using the UP or DOWN display buttons on the screen. (There is a chance that your Component was actually manufactured by another brand.) However, most of the code tables are so large that it is usually faster to use the Learning Method.
7. Point the RF20 toward the Component you want to program, (in this example, TV), and punch in the 3-digit code that you wrote down for that specific Component. Use the Number buttons 0-9 on the remote to punch in the code.  If the 3-digit code number that you just punched in is correct, the Component will turn off.  If the Component does not turn off, continue entering code numbers from your list until the Component turns off. Some brands have several possible code numbers.
8. When the Component turns off, press the ON button to turn the Component back on. Now you can test the Volume and Channel buttons (for TV), or PLAY and STOP (for VCR and DVD) to make sure they all work. If any of the buttons do not work properly, you need to find a new correct code. For example, maybe your Sony TV turned off with code number 147, but the volume controls did not work properly. If this is the case, try the next code number listed for that Component until you find a perfect match.
9. Once you have found the right code, save the code number by pressing the SAVE display button that appears on the LCD screen. The LCD screen will blink “SAVED” two times, signalling that the code number has been successfully saved.
Exit SET-UP mode by pressing the MAIN button two times.  When the LCD screen displays MAIN, you are back in normal operating mode.
[now, program the rest of your components by repeating steps 1 through 9. In most systems,you can finish basic setup in just a few minutes and put all your old remote away.  If you are still missing commands to control any of your components, use the learning method]
LEARNING METHOD
1. Line-up the RF20 with the other remote control, head-to-head, one or two inches apart.
2. On the RF20, press and hold the MAIN and ENT (Enter) buttons at the same time for approximately three seconds, until the word “SET-UP” is displayed at the top of the LCD
screen. This signals you are now in SET-UP mode. {You now have 30 seconds to perform the next step while you are in SET-UP mode. If you don’t press a button within 30 seconds, SET-UP will disappear from the screen, signalling that you have exited set-up mode and you will need to start over.}
3. Press the LEARN display button on the LCD screen. The top of the screen will change to “LEARN” and display the five Components from Page 1 of the MAIN menu. [To display Page 2 of the MAIN menu that lists an additional five Components, simply press the PAGE  ▲/▼  buttons,]
4. Select the Component you want to teach commands to by pressing that Component display button on the LCD screen (in this example, TV).  The top of the TV screen will change to “TV” { If you want to teach any command to a Component button, press the desired Component display button once the top of the screen displays “MAIN”, by pressing the PAGE button.The top of the screen will change to “READY”. Then go to STEP 6.}
5. Press any button on the RF20 that you want to teach a command to. The top of the screen will change to “READY” and the bottom of the screen will display the button name you
Pressed. If you don't see the display button you would like to teach on the LCD screen, use the PAGE ▲/▼   buttons. The only buttons you can't teach are the PAGE and MAIN button.
6. Press and hold the button on the other remote control that you want to ‘teach’ to the RF20 until the LCD display on the RF20 changes to either “GOOD” or “FAILED”. If the “GOOD” label appears on top of the display, you were successful. If the “FAILED” label appears on top of the display, try ‘teaching’ the same button to the RF20 once again by repeating STEPS 5 and 6.
7. Now, continue to teach the RF20 any other commands from your other remote by repeating STEPS 4 through 6 (to go back to STEP 4, simply press MAIN once).
8. Once you have completed teaching all the button commands to the RF20, return to normal operation by pressing the MAIN button twice.
[Test all your new commands.  If any of them don’t work, try the Learning Method again, following these suggestions:
* Move to another room. Plasma TVs, sunlight, halogen or quartz lighting can interfere with the learning process.
* Even though the old remote seems to be working fine, put in fresh alkaline batteries.
* Gradually vary the distance between the remote controls. Try 1”, 2” and so on, up to 4 feet.
* Try tapping the button on your old remote instead of pressing and holding it during the learning process some additional Information regarding the Learning Process:
* Learned functions override any existing pre-programmed functions on the remote control.
* All buttons can be learned except for the PAGE, MAIN and LIGHT buttons.
* Learned functions are automatically erased when a new function is learned on the same button.
• Learned functions are retained even after a different Set-up Code Number is programmed into the remote.
* To return to an original pre-programmed function, a learned function must be erased
