Switches off after five seconds.AVR-590

There are a few things that could be causing this to happen. The first thing you should do is check all the speaker wires connected to see if they might be touching each other somewhere. What you are describing sounds like there might be a short. Also, is the receiver well ventilated? What is happening is that it is protecting itself but shutting off.The 590 is going in to Protection Mode due to some fault it perceives. The quick flashing red power light (as opposed to a slower flashing light) would indicate either speaker wires touching another terminal, driving 4 ohm speakers to loud, or amp failure.

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

Sharp LC-26D43U Power light flashes and unit won't turn on?

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.

Here's a place I use to get parts for TVs:
The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

Tv Turn sound on, No Picture, turns itself off within seconds

The TV is trying to go on protect mode because an internal fault had been detected. For that reson the protection circuit keeps turning off TV continuously.

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

THREE Blinks
B+ over voltage protection (OVP), unit goes to the standby
mode then displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
FIVE Blinks
AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.

Amp comes on and goes right into protection mode

Turn the reciever on for a second or two and then off before the protect mode shows up on the monitor. Repeat this step about five times and check to see if the reciever does not go into protect mode. If it does go into protect mode try it again. Dont know if this is the proper way to fix the reciever but it worked for me. Good Luck

You have a short in the internal power of this unit. It is going into protect and shutting itself off to keep it from damaging anymore of the internal electronics. Very likely a voltage regulator has gone bad or a power capacitor has gone bad. You will not be able to repair this yourself unless you are skilled in electronic repair. I would suggest contacting the manu and seeing if they have a authorized repair shop in your area. If not ask around and see who is a reputable repair shop in your area.

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.
