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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

SOURCE: Picture judder on Pioneer plasma TV

i wouldn't be worry if:
If the tv just does this phenomena for some seconds specially when there is a change from video analog to digital.
if the tv does the issue only for some seconds and then gets back to normal and stays there for the rest of the day.

SOURCE: black bar

On a non H.Def plasma, there is a PCB that runs along the bottom of the screen that is attached to the screen by a several brown/gold colored flat ribbon cables. I've seen where this ribbon cable is not seated properly in the jack. The ribbon cables are generally responsible for that section of the screen. Next possibility is the PCB itself is defective.
Not to scare you, but the plasma screen itself is a possible suspect.

SOURCE: dynex 32" tv picture goes black

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

I've been having a few problems with my LG


Good morning to you! When the screen goes black, have you tried to go into setup on the remote. Adjust the brightness of the screen. Or as I am sure you have done to restart the TV when the warning sign comes on the screen that the TV will go off affter 5 min. The classical action is to disconnect both the router and the box that keeps all the stations in it. Disconnect for 2-3 minutes, connect again. I do apologize for not knowing the name in English. ( english is not my mothertounge) Hope this can help you on the way. Then there is always the user manual that can be downloaded free and look in the troubleshooting page. ( I did that the other day, had lost the paper onr) Kolbrun

LG 42LC46 ZC AECVLJG about 6 years old, we r having trouble switching it on. There is no red light on or sometimes it flashes on and off, usually it has been a good set. we r with sky and HD, ca


The most likely cause of this problem is the power board.

Take the cover off, make two-three good high-resolution up-close shots from different angles and send them so we can tell you if there are visible issues with it.

For more detailed troubleshooting you'll need a voltemeter and tons of patience.
