Is this a new set-up, or have you always used it as it is?

It could be source #1 and#2 are both feeding the input and causing interference. You need to switch between the two, or turn one source off.

    It could be the chip controlling horizontal hold if it keeps scanning.

    You may have caused a spark-overload when unplugging or plugging in systems while on.



    In that case it needs a tech to take it apart and trace the issue, unles you are trained in repair of electrical systems.

    crack or cold solder is very dangerous of the unit because correct current flows to the circuit cannot pass due to a crack of solder or higher current cannot supress or limited and cause burnt of the spare parts and that's why abnormality comes out,like swift interference ;automatic shot off of unit and many problem .If this cannot be stop and your unit will be dead set ;due to burnt spare parts, stop this as early as possible ,by reheating what im state above...

If you unplug video 1 and 2 does it still do it? If not then either your cables are not grounding properly or there is a problem with one of the board or ICs in the TV. Try only 1 of the two inputs at a time then switch to see if you can determine if a certain input or device is causing your problem.

    Video card has become slightly loose in its slot, or that one of the
    cables – possibly the cable going from the monitor to the video card –
    has worked a little loose, or has a bent pin. Bent pins can often be
    properly repositioned by hand, or with the aid of a simple household
    tool like a tweezers. If the cable and connection appear to be okay,
    power down your system, unplug the computer’s main power cable, pull
    off the computer’s outer case, and try removing and reseting the video
    card.

    Monitor is plugged into an old surge protector or buzz strip, which may
    mean that the monitor is being supplied with insufficient or ‘dirty’
    (uneven) power. Is there a power light on the surge protector, and if
    so, is it flickering? If so, try plugging the monitor directly into the
    wall, or into a brand new power strip.

Television screen is green


Is the picture in a green shade or the whole screen is simply green?
if the second one is currect - the connection to the video source is lost. some tv do a blue or a green screen in order to prevent that anoying sound that the old tv used to make.
try to reconnet your source (PC or a DVD player, whatever you can).
if it works on other devices - your device is probably damaged.

My Sony LCD HDTV, 60", about 6 years old, times out after about 35 - 40 seconds and I lose video and audio while the power light blinds. After about 35 - 40 seconds I get video back and a few seconds...


Try this...... Remove the front panel to access the bulb. There are 2 screws on either side of the tv right behind the screen. You may be able to remove them with just your hands. It will make sense when you see them. Once they are loose the panel will pop off. There are 2 magnets that help hold it on, so just pull gently. In the middle you'll see a another scew that you need to loosen. Slide the bar off, remove the cover and you'll see the black box that holds your bulb. There is an allen screw on the left side that will need to be loosened. Once that is loose, the whole unit slides out. Is the top of the vent screen really dirty? If it is, flip it over and try dusting it off with a soft brush, maybe a tooth brush. Try to keep most of the dust out of the bulb itself though, just be gentle. Pop it back in with the reverse order.......

it might be coming from the actual audio/video source. try hooking up a dvd player or gaming system and see if it still does it.

Blue screen


Are you using component video cables? If so, check that these aren't loose on either end. Next I'd consider that whatever video cable/input might be bad, and switch cable or cable type... i.e. switch from component to HDMI or vice-versa. Then change up the source (cable box versus DVD player). If you're still seeing blue at this point, the TV internals are the bad.
