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.

RCA TVs _ GENERAL PROBLEMS AND SOLUTIONS _ DIGITAL TRANSMISSION RECEPTION PROBLEMS _ Picture does not Fill the Screen _ HDTV making Low Buzzing Sound






IS THE TV IS PREPARED TO RECEIVE DIGITAL TRANSMISSION

 The Digital TV Transition has been introduced by June 12th, 2009, all televisions will need a digital tuner to receive over-the-air broadcast signals. On newer models, the tuner is built in and no new equipment is necessary. If you have an older model, you can still use it. You'll just need to pick up a converter box.

 PICTURE DOES NOT FILL THE SCREEN BY NO WAY.

 The format of the picture that you see (16:9, 4:3, etc.) on your TV is determined by the broadcaster of the program that you are watching. 
So, you may see bars on the top or side of the TV screen even though you have a widescreen TV. Sometimes, the TV program is broadcast in a format that you cannot change with the remote control. Other times, the picture is broadcast in a manner that can be changed. 
One way to check to make sure that everything is working properly is to go to several other channels to see if you can change the format.

 ON SCREEN PROGRAM GUIDE INFORMATION ON HDTV IS WRONG

 Make sure the antenna is properly setup and receiving strong signal.  
If this does not correct the problem, it may be necessary to disable your system's ability to acquire off-air TV program guides.


  1. Press MENU on the remote to access the Main menu.
  2. Select the Assistance menu.
  3. Select Off-Air Guides.
  4. Select Do Not Acquire Off-Air Guides.
  5. Exit from the menu.
  6. You will now need to rebuild the channel list.
  7. Press MENU on the remote to access the Main menu.
  8. Select the System Options menu.

Select Channel Search. The system will run a channel search making it aware of all of the TV broadcast channels that the HDTV monitor can receive.

 HDTV MAKING LOW BUZZING SOUND

 It's possible that a power surge may have activated the electronic protection circuit. Wait 30 seconds and then turn the TV on again. If this happens frequently, the voltage in your house may be abnormally high or low.
