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!

TV POWER LIGHT COMES ON – BUT NO PICTURE OR SOUND

TV POWER LIGHT COMES ON – BUT NO PICTURE OR SOUND.................


Power light on TV is ON but no pic and no sound? The power ON light or standby light on my TV comes ON sometimes blinking but no sound and no picture. My 55″ Samsung TV has a small light on the bottom of the screen. When I press the remote control to turn the TV ON, the light for power ON is illuminated. However, I see no picture and hear no sound. This is the first time this has ever happened. I have tried all reset procedures possible including unplugging the TV for 10 minutes. Is there a reset method for a flat panel TV or could this mean something in the TV is burnt or faulty?



Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 – Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 – Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 – Make sure you are on the correct input as some TV’s will show a black screen if there is nothing connected to that input.
4 – Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 – Check for signs of damage on all cords and cables from the TV to all components.
6 – Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.


7 – Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 – Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 – If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 – Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.




TV Power Supply Boards, Why They Fail?
The capacitors on a Power Supply Board may get a surge from a power outage or something else and fail or “pop”. Examine the Power Supply Board and look for popped capacitors or fluid that is leaking from the base of the capacitors or the tops. The capacitors are located on the power supply board in the TV where the power cord plugs into. Also check the Power Supply Board for burnt or any damaged components. REPLACE CAPS IF NEEDED or REPLACE BOARD IF NEEDED.



All of the above methods to troubleshoot why your TV has the power light ON but no sound or picture applies to all brands of TV’s including LG, Samsung, Sony, Sharp, Toshiba, Vizio, Insignia, Element, Etc…
NOTE: If this happens with a Vizio TV, usually you will see the green light and a red light in the triangle under the Vizio name on the front.
