Hi,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault was the dried/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit and blinking error appear. Sometimes it has a bulged/dome at the top but not all, you must have a capacitor checker/tester to determine its condition to pinpoint where the faulty one. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Another reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Samsung TV won't turn on. Red light is solid, won't blink when pressed. All capacitors seem fine (none swollen or vented).


That model is covered under a class actions lawsuit settlement over bad power supply boards. You need to contact Samsung about this and get a warranty claim started, even if the original warranty is over the settlement terms will cover parts and labor. You can get additional information about this along with contact information here: http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

The red "on" light is blinking and the TV


a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

The television will not turn on. the power button on front of tv has red light that is constantly blinking. why cant we power it on.


It is sensing problem and staying in safety shutdown mode, it can be due to bad DC power due to bad caps, shorts circuits in the backlight inverter board, main laogic board problem. Power supply voltages should be check first. You will need to do in-depth troubleshooting.
