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.

HOW TO PROGRAM RCA RCRN-04GR UNIVERSAL REMOTE CONTROL

HOW TO PROGRAM RCA RCRN-04GR UNIVERSAL REMOTE CONTROL




PROGRAMMING PROCEDURE
Direct Code Entry
Direct Code Entry lets you enter a code from the accompanying code list for your brand of device. It’s not as easy as the other methods, but it’s potentially the fastest method.  [Each device key is associated with a type of device the TV is preset to search for TVs, SAT•CBL•DTC for satellite receivers, cable boxes or digital TV converters, DVD•VCR for DVD players, and DVR•AUX for DVRs. To program a device key for a different type of device, see the Changing a Key’s Device Type section.]
  1. Manually turn on the device you want to control.
  2. Find the Code List that came with the remote. Locate the section for the type of device you’re trying to program, and find your brand in that section. Circle the codes for your brand and keep them handy.
  3. Press and hold the device key you want to program (the POWER key illuminates).  While you’re holding down the device key, use your other hand enter the first five-digit code for your brand in the code list (the POWER key turns off after the first digit).
  4. When you’ve finished entering the five-digit code, keep holding down the device key and look at the POWER key.
  • Is the POWER key illuminated?  If YES: You’re done! You’ve programmed this device key.
  • NO, it blinked four times and turned off: You have either entered a code number that is not in the code lists or missed a step in the code entry procedure. Try step 3 again.  [Test the remote with the device to make sure the device key is programmed with the correct code for maximum functionality. If some features don’t work, try a different code in the list.] 
  • If your brand isn’t listed in the code list, use one of the Code Search methods to program the remote control.  If you release the device key any time during the Direct Code Entry procedure, the POWER key blinks four times, and the process is exited. The last programmed code under the device key is retained.
MANUAL CODE SEARCH
The Manual Code Search lets you go one-by-one through all the codes for the device you’re trying to control. When you find the one that operates your device, you can stop the search and store that code.
TIPS: The Manual Code Search method may take a long time because the remote searches through all of the codes in its memory one-by-one. If your brand is listed in the Brand Codes or the Code Lists, first try the Brand Code Search or the Direct Code Entry method.
Each device key is associated with a type of device the TV is preset to search for TVs, SAT•CBL•DTC for satellite receivers, cable boxes or digital TV converters, DVD•VCR for DVD players, and DVR•AUX for DVRs. To program a device key for a different type of device, see the Changing a Key’s Device Type section.
To exit without saving a new code at any point in the Manual Code Search, press the EXIT key.
  1. Manually turn on the device you want to control.
  2. Press and hold the device key you want to program. The POWER key illuminates.  While you’re holding down the device key, use your other hand to press and hold the remote’s POWER key at the same time. The POWER key turns off.
  3. Wait until the remote’s POWER key comes on and stays on. Then release both keys.
  4. Point the remote directly at the front panel of the device you want to control. Press POWER on the remote and wait 2 seconds. The remote is testing a single code for your device.
  • Did your device turn off?  If YES: Press the STOP key to store the code. You’re done! You’ve programmed this device key.
  • NO?  Press POWER again. The remote tests the next code for your device.  Keep pressing POWER every 2 seconds until your device turns off.  When it does, press STOP.  Because there are so many codes, you may have to press the POWER key many times - possibly hundreds of times.
  • Test the remote with the device to make sure the device key is programmed with the correct code for maximum functionality. If some features don’t work, try a different code. During the Manual Code Search, the remote ignores keypresses that aren’t part of the search.
  • The search times out after two minutes (the POWER key blinks four times and turns off, and the last programmed code under that device key is retained).
  • The POWER key blinks four times and turns off when the remote has gone through all the codes. The remote exits the Brand Code Search. If your device hasn’t turned off yet, try a different search method.
TESTING THE CODE FOR MAXIMUM FUNCTIONALITY
  • Try a variety of the device’s functions with the remote. If some features of your devices don’t work, go to the next step to try a different code.
  • Repeat the Manual Code Search and Entry Method from the beginning. When the device turns off for the first time, don’t press the STOP key, which would store the same code. Instead, with the unit now off, continue to press the POWER key repeatedly until the unit turns back on.
  • Once the unit turns back on, you have found another code that operates the device. Press the STOP key.
  • Test the key’s functionality again by trying a variety of functions. If the code controls the majority of the device’s functions, programming is complete. If the code stored does not give maximum functionality, try another code.
CODE RETRIEVAL
Once you've programmed the remote to control your devices, you may want to record the codes for future reference. If you used the Direct Code Entry method, this is easy. Just find the codes you entered and make a note of them in the boxes below. If you used one of the Code Search methods to program your remote or if you used the Direct Entry method but don’t remember the code, you will need to retrieve each device’s five-digit code. Retrieving the actual code and writing it down will save you time if you ever need to program the remote again. If the codes are recorded, you can use the Direct Entry method to reprogram your remote to control your devices, which is quick and easy.
  1. Press and hold the device key (TV, SAT•CBL•DTC, DVD•VCR, DVR•AUX) whose code you wish to retrieve. The POWER key illuminates. Keep pressing the device key.
  2. While holding the device key down, press and hold the INFO key. The POWER key turns off. After holding down both keys for three seconds, the POWER key turns back on.
  3. Release both keys. The POWER key remains on.
  4. Starting with the number 1 key, press and release each number key on the keypad in the following order: 1-9, then 0. The number that causes the POWER key to blink is the first number of the code. As you find each number of the code, write it down for future reference.  All TV codes begin with the number 1; all VCR and DVR codes begin with the number 2; all DVDs, the number 3; and all satellite receivers, cable boxes and DTV converters, the number 5.
  5. Repeat step 4 until you have retrieved all five numbers in the code. After the fifth number is retrieved, the POWER key blinks briefly, then turns off.
  6. To exit the Code Retrieval Mode at any time, press the EXIT key.
Note: If you press an invalid key during the Code Retrieval process, the remote will not respond. If you do not press a valid Code Retrieval key (TV, SAT•CBL•DTC, DVD•VCR, DVR•AUX, INFO, EXIT), Code Retrieval times out after 15 seconds. The POWER key blinks four times, and then turns off.
