A component inside the tv is causing a short, which in turn , is causing the protection circuit in the tv to shut it down. It could be a lot of things which are causing it, but it definately sounds as though, to me anyway, that is the cause. It could be something like a failed capacitor on the power circuit, or it maybe a IC that has a dry joint, the only way to know for sure would be to open the tv and check, not advisable if you are not trained to do this. There are high voltages in these tv's that can seriously hurt or even kill somebody. If you want you could open it and just check for bulging capacitors. they look like this

good caps look like this


to test other components would require a multimeter and a service manual to get the correct readings to check for.

Next time you ask for help though a tip would be to supply the make and model of tv in your question

When you switch the TV set on, the picture comes up for a second or two then the set turns it's self off onto standby

It sounds like you have a power / short issue. You will probably have to get it looked at and serviced, but you could try plugging it into another power outlet in the house, but first leave it unplugged for about 10 min.

Lcd32880hdf 10 months old. When switched on the picture disappears after 2/3 seconds and will not come back on. Sound still remains un-effected.??

If you can quickly get to menu before picture goes blank, then go picture / backlight / set backlight to minimum and it will work fine.

Camera switching on ok but lcd sceen blank

Your problem can be the result of a number of causes - two common ones I will list here.
Most common cause would be a failed printed connecting cable between the main camera electronics and the flip out display panel. This special cable passes through the display hinge and is sometimes subject to failure.
A second possibility is a faulty display backlight.
You can check that the camera is still producing video output by using the AV cables conected to a TV display with the camera set to CAMERA mode.
I trust that this information is of assistance. RHN

Monitor displays the PC screen but switches off within 10 second

Unfortunatley your monitor is going out. I just had that problem. My sceen would come on, but after about 10min. it would blink off and turn black. I would have to hit the off button on the monitor, then turn it back on. It would work fine for a few minutes then black out again. I got a new/used monitor where I no longer have that problem.

I did check to make sure my hybernate was not activated, it wasn't, I had it set to never turn off.

Good luck.
