SOURCE: Red blinking led

My 42" Philips LCD did the same red blinking sequence last night. All was seemingly fine after unplugging it for a bit. An online search, though, has me worried that this may be the start of (potentially fatal) power supply issues. Anyone have a clue what that sequence means?

I've got one week left on my 1yr waranty, so I'm a bit concerned! :(

Thanks!

SOURCE: red blinking light

The red light blibking 6 times indicates that the power supply board has a defective or damaged area. I know this because i had the same problem...bought a damaged tv for parts and replaced the power supply board as the tv would not turn on...wokrs like a charm now.

SOURCE: tv wont turn on and automatically shuts down

I'm having the same issues with my phillips flat panel. I downloaded the firmware update from phillips and that helped...but only once. I'm back to the same issue this morning. But you might try this download...it may work for you.

SOURCE: What does the 6 slow blinking red lights followed

Try unplugging the TV and then plugging it back in after a bit (at least 10 seconds). In several cases, the TV will start to work for a while.

However, the blinking indicates a part or parts that are getting close to failure. Most often this is 2-4 capacitors on the main board. These can be replaced (either by yourself or by a technician if the TV is under an extended warranty). Radio Shack will have the parts; a site called tvrepairkits.com has many prepackaged sets - check for your model.

I hope this helps.

Mitsubishi hdtv 1080 what are the blinking green light codes


ost models have a self-diagnosis feature to help determine shutdown problems.

To enable this feature do the following....

1) Turn the tv on and then let it shutdown
2) Press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds
3) After 5 seconds the power LED on the front panel will blink a two digit sequence.

This will commonly be one set of blinks followed by a short pause then another set of blinks.
This will repeat around five times.

1 - 2 = no error detected

2 - 1 = X-ray protect (high voltage or beam current)

2 - 2 = Short protect (short detected - commonly caused by convergence failure - to repair this check out site for a convergence kit)

2 - 3 = Deflection protect

2 - 4 = Vertical protect


Note: A constant blink on certain models will typically be caused by a fault in the DM model. To repair this check out site a "blinking green light kit"

Sharp tv wont turn on


Does the power light come on? Does it blink in long and short durrations. If so count them and get back. Example 2 short and one long blink.If no power light at all problem is with the power board.

I have a WS-65907 tv, it wont turn on


Mitsubishi self check: MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu" buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC's is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

My sony kdf e50 12u wont turn on red light blinks twice


Your TV is giving you a code, something is faulty in the system, usually 2 blinks of the red light indicates, Load on power line is shorted. I also would check the bulb also to make sure it doesn't need replacing.

Tv wont turn on, the power indicator nor the remote receiver light does not light up, the 3rd circle on the front of the tv blinks red!! But it wont come on regardless, tv is only 2 years old, what to...


The blinking red light means set is in shutdown because of a short inside the tv.

Someone to begin would have to open it and check power supply voltages inside the set....that is the first step.

Tv wont turn on


The green light flashing indicates an error code, plasma tv's cannot be repaired at home without the right equipment and service manual, the fault could be power supply, processor or virtually anything, what technicians look for is the frequency of the blinking and the time between sets of blinks, this normally gives the tech a code that enables them to go to the right area, the only thing anyone can tell you is that the processor is probably ok, you really need to get a quote or count the blinking and the timing eg: "blink blink short pause blink), and repost the fault, then we can possibly tell you where to look...Phil

7 blinks followed by 8 blinks


The buzzing sound you hear is typically the FBT shorting out when you turn the TV on. If you open the back panel and watch the FBT as you try to turn on the TV you can see it shorting out. It will be obvious.

3 blinks means the convergence circuits are shutting the set down. Usually the convergence ICs will take care of the problem, but I would recommend getting the service manual from the following link, as they will provide you free support to help you diagnose why it wont start as usually the convergence ICs wont prevent a set from powering up, unless another component in the convergence circuit has failed.
