SOURCE: No picture, but power is on...

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)

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.

SOURCE: After a momentary power outage Panasonic LCD TV has a flashing red light and will not turn on.

Try using a different outlet, the outlet or the tv may have been damaged in the surge. In the case of the tv contact the manufacturer and see if it's still under warranty. There may also be a way to 'reset' the tv by holding the power button down, try looking in the manual or calling customer support. In the future use a surge protector, many of today's electronics are still sensitive to power surges, older tv's were more resilliant than today's in this regard.

SOURCE: Display powers of with power up of AVC

This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.

Panasonic tc p50g15 tv will not turn on tried 1 minute unplug reset and 20 sec power button hold in. Did not work now no led lights


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

This sounds like a main power board issue. After you unplug it, it will work? Are you planning on trying to service it or having it serviced?
Thanks,

Sony KDF-50E2000 shuts down and blinks repeatedly twice.


The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.
