In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Hi,
A faulty Tcon board is often found responsible for wrong colour type faults. Some times the main board is also found faulty. If it has happened all of a sudden, it is not aging.

would say that the screen lights have gone. usually they flicker for a while then come on. then off etc. more than half the screen has gone so the power from the inverter is not being used so it turns off the tv. it is a very fiddly job replacing them as you can damage the screen in the process. more easyer just to get a new screen.

you could try returning in all of your channels from the main menu the tv can do this automatically but you need to select the procedure
1. click on the home button
2. scroll sideways till you reach settings
3. in settings scroll down or up and click on digital set-up (centre button of your scroll control)
4.then scroll down to, and click on digital auto tuning (centre button of your scroll control) this will activate automatic channel tuning the tv will do the rest and will wipe out old settings and retune in all channels

Hi, this could be a problem with the power supply in the tv, it is common especially on some Samsungs and specific repair kits are available quite cheaply if you have good soldering skills, this can also apply to many other Flat Screen TV's .

Usually this is caused by capacitors that have dried up and split, you can normally tell as the capacitors are bulging on the pcb, you can get them in a kit as I said eBayer's sometimes do them or you can buy them indivually from a good electronics components supplier, make sure you get the correct values for each!! marked on the side of the capacitors in xx/x V, xxx/x uF and 105oC. (the x's represent numbers)

The picture below shows the type of theing that happens, the brown ones are bulging/split on the top whereas the black one is fine.

High Voltages can exist in these sets, never attempt anything while plugged in and
if in doubt do not attempt it yourself and seek the advice of a qualified TV Technician.

There could also be dry solder joints on the panel, usually applies to the power supply as it's mainly these get the hottest.

Here's an example of what dry joints look like.....

It's also worth considering claiming under the warranty for replacement or repair through you dealer if warranty is valid.

Hope this helps (: don't forget the thumbs up if it did :)

Hello,

All plasma an LCD ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken.


Hope this help in solving the problem......
