I had to purchase a new one when that happened to me. Power surge fried it.

I'm not a tech. but i would pull the face plate off and check the battery also see if there is a fuse that could have been blown.

I am a hvac tech, it should just resume normal operation. I would check your breakers if it's not coming on more than likely you have an issue elsewhere.

I have this same problem. Do I need to replace the main circuit board or the display board. I can get all readings, just no lighted buttons such as power, generating etc.

Do you have your manual for this unit? If not, you can find it by searching for just the number pt43LC14. I pulled up the manual on the internet, it is a PDF file so just right click the file that says Multimedia Projection Display Operating Instructions and download it to your computer. Here is the link: service.us.panasonic.com/OPERMANPDF/PT43LC14.PDF. and according to your manual you have only two options with a yellow blinking light: Power Indicator Flashes orange 1 time every 5 seconds. Power shuts off. The internal cooling fan is not working. Contact service center. Flashes orange 2 times every 5 seconds. Power shuts off. The Lamp Cover is unsecured. Securely attach Lamp Cover. If you have a bad bulb it will flash red. If the bulb is totally burned out, like mine recently was, the TV will just flash green then red.

Thank you all for your comments and tips. Ive just exchanged the monitor for another unit and the replacement unit does not have the same first start/powering on flickering. Btw, i tested the original unit on a ps4, 2 diferent desktops, and a laptop each with their own cable but the result were the same. In the manual it stated that flickering is "normal" due to the nature of the LED backlit, and call support only when the monitor no longer power on due to the flickering. (...?)

Same problem. I just opened the unit and so far I love it, but on night vision there is no constant image. It keeps "blinking" from night vision image to black, back and forth. Is this normal? I was expecting uninterrupted image in night vision as when there is light on the room. By the way, when I turn lights on, the blinking desapears. Can anyone help us with this?

Mine was a little slow to start accepting commands at the beginning, but I just worked with it awhile and it started working. All I can say is keep trying, and try unplugging and plugging the power cord for the main unit also. If that doesn't work the only option is to return it for another one. Does the lights come on in the viewing window when plugged in, you should get something.

Unplug the lcd connector and plug it back, but if that doesn't work probably is the lcd problem, try with different lcd

Check for loose wiring/loose fittings first. Second would be to try changing the resolution on screen. Last would be your monitor is going out. Let's hope that's not it.

Yes, the same thing happened to me. Before attempting to hook up this converter, right click, go to screen resolution and check what your screen resolution is. Then go ahead and hook up the converter. Now, with the converter connected, go back to screen resolution, and for your second screen, change it to what it was when you checked it before the converter was connected. This should fix the problem. For me, the screen completely stopped going on and off. If it still blinks, just make small adjustments up or down to the resolution until it's fixed.

sorry it took so long to get back, just make sure u got all the connectors plugged in and have a good power supply. try to test the power connectors if there not a name brand on something u know that works to rule out a fault power connector

Did you power on the PC? If so try and unplug and start over. If it will not power on it may be DOA.

Help! Same problem. Ours worked for less than 24 hours and will not turn on at all, no light, nothing. It doesn't even almost come on. Blank. Screen. Frustrated!!

I am having this problem too. I tried the power reset and tried playing with the screen to reestablish the connection, but neither worked. Are there any other suggestions out there?

i just took mine into the shop for the same problem, very irritating hearing it turn on and off all the time just to start, it would take like 10 minutes for my tv to finally turn on, the technician at the shop said the power supply was bad and i wasn't getting enough power to the main board to turn the TV on, 200 bucks later, I am happy, fix it, it is worth it.
