Question about Liquid Video E17LCD1 17" Flat Panel LCD Monitor

LCD blinking on and off continually

Hi, my problem is that my LCD blinks on and off, on and off, on and off, and so on. I have tried unplugging it from both power and the computer but it continues to blink on and off. Any suggestions would be greatly appreciated. Thanks.

    mine has been doing the same thing and then it says No Signal Input, then shuts down. I do believe it's time for a new monitor, I have had for about three years or so. Mine is a A17OE1-01

If it flashes ON and OFF when simultaneously unplugged from both power and the computer then it's trying to communicate with you. Mine flashes code to me. It tells me what to do. Last night it told me to get it $5,000,000 in unmarked bills. Seriously, turn the monitor on without connecting it to a computer. If it flashes ON and OFF continously, then you have either a bad monitor or a bad AC/DC power adapter/brick (you know, the rectangular black corded adapter you plug into the wall outlet). If it only flashes ON and OFF when connected to a computer, try the monitor on another computer. If the monitor is 3-4 years old, it may be time to replace it since a replacement AC/DC adapter might be very hard to find. Let me know what you find out, if you need more help.

    Sidenote:

    Now that I've had a refreshing night's sleep and can think better, I mentioned the AC/DC adapter above, I don't really think that is the problem in your case.

    What I believe is wrong in your case is:
    the flashing ON and OFF is normally caused by a bad ballast capacitor on the inverter printed circuit board (PCB).

    This can be replaced/repaired by a competent technician, although I'm sure the repair and shipping costs would almost equal 3/4 of the purchase price of a new monitor.

    Time for a new LCD?

The red light is on and when I try to turn the TV on it flickers as if to come on and then nothing.


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. http://electronicshelponline.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Tele turned itself off, red light blinks 4 times then pauses and blinks 4 times again.


You can try unplugging it for a while and then plugging it back in, but according to the manual, the standby LED:
Lights up red when your TV is in PC power saving mode. If the LED blinks in red continuously, this may indicate the TV needs servicing.

Hi,
4 times red standby light indicates problem with exhaust fan that is not running for some reason.
Recheck fan that you replaced and make sure its connector is plugged properly and it running freely.
4 times red light blinking is fan error in this tv.
Thanks.
