Take out the antenna for fm/am and it should work :) disconnect speakers as well and make sure wires are fit properly in there spot. Maybe switch the Left speakers to the right input and vice versa. I did all this and it works again. yaya

What's your problem?powerprotection mode unlock


If the protect function works and causes hindrance to trouble shoot, cancel the protection function as described below, and it will be possible to enter the self-diagnostic function mode. (The protection functions other than the excess current dtect function will be disabled.)

While pressing the "Tone Control" and "Info" keys, press the "Power" key to turn on the power and keep pressing those 2 keys for 3 seconds longer.

The seld-diagnostic function mode is activated with the protection functions disabled.

In this mode, the "Sleep" segment of the Flourescent Display flashes to indicate that the mode is self-diagnostic function mode with the protection functions disabled.

Caution!!!! Usiong this product with the protection function disabled may cause further damage to your unit, so use special care when using this mode.

I have a 32PFL5332D and when power turned on red light flashes 6 times then stops blinking for 3 seconds and starts again over and over. TV never powers up


Im afraid the set is probably in an over current protection mode wherebye it shuts down to protect itself as one aaea of the tv is drawing excess current, the pattern of flashes will have a code which would guide a techie to problem area, im afraid you will need an engineer visit,sorry George

Protect keeps flashing


Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
