TV won't come on, just blinking red light...

I've read that it could be one of the lamps or a convergeance problem. How can I truly know which one it is so I don't have to spend too much?

Thanks,
Will My tv won't come on and the red light keeps blinking. It blinks 7 times then pauses. What does this mean?

Red LED blinking after turn on the TV


These blinking codes are fault indications. By counting these, you can understand the location of the faulty section inside it. But, counting these blinks too is somewhat difficult to a user who is not aware in electronics. Check this link, and see how to count the standby light blinking codes to Philips brand TVs. Details are described there in detail.

Sansung model 56 Inch hpl5663w first had a buzzing sound the tv repair man said it might be a color wheel but the tv played well except for the low buzzing sound . then one night the picture went black and...


Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

When you turn on power you hear a click and the green light turns on. Three seconds later you hear another click and the green light turns off.


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR 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 bothtogether.


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 protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE 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 twoblinks--this is the most common and easiest to fix.

Let me know what you find and I will assist you.

TV red light blinks seven times. Is this a code for the problem?


Hello,

Yes, it is a code for the problem affecting the television. 7 blinks most likely indicates a power problem and in some cases, it indicates a bad lamp problem.

When you open it up is when you will be able to tell which exactly is the problem with the television.

For power problem, it might be that there is a burnt capacitors on either the main panel of the power panel.

Once you check you will be able to detect it and replace it with a new one, and if it also is the lamp, that way you will be able to tell and replace the lamp if it truly is the problem.

Take care and good luck

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.
