Picture jumps after a few hours turned on

That may be a bad T-CON board, but more likely it's a fault in the LCD panel itself. Check whether it's under warranty before doing anything else.

sounds more like a photo control board issue you can contact samsung to have your tv serviced

Check the left connector from the Tcon to the panel, if its ok replace the board

Your picture tube is on the (Verge) Of going.

There is a Anynet Setting under the input tab. It has to be on the right setting or the picture Jumps after 20-25 minute. Once I adjusted it to the right setting it stopped jumping and it now works Perfect. Would nt have figured it out if I wouldnt have been messing around with it as a last chance deal.

If this jumping is accompanied by a sharp snapping sound, it may be the high voltage circuit discharging to chassis. Leakage can cause the jumping and a discharge can momentarily blank the picture.

If you want to try a 'cleaning cure,' I suggest you pull the plug (not just turn it off) for several hours, preferably overnight. Sets of this size can carry enough static charge to punch a hole through your thumb if you get careless.
Remove the rear housing (shouldn't be more than 6-8 screws) and using a clean paintbrush, and possibly a vacuum to **** up the dust, clean it well and pay special attention to the area around a largish misshapen black plastic object bigger than most anything else and connected to the back of the picture tube via a fairly thick cable.     

you might have bad caps or the vertical output integrated circuit, try to locate the vertical ic and check the surrounding areas for bad capacitors.


good luck

Probably a 'cold or detatched' solder joint on a component on that perticular circuit board you are 'wedging' with a plastic rod.

it needs the hyper module replaced might as well have em do the stk packs too its too old to be a lemon the part that was replaced was not new it was in someone elses tv and had problems there too the trick is to find someone that will fix it so it lasts
