Hit the side of the tv and if you can get it to come good for a sec then you have dry joints on the main board.
hope this helps

I have just bought a new wide screen Samsung TV but I can't work out how to switch it off completely. It always goes into standby mode


Have you tried pressing the standby button, and then the on/off button afterwards? Sometimes they need combinations of buttons, to work. It happened to me. I dont know if it will, but i hope this helps! :-)

Tv went black and no sound standby light falsh twice and paused and flashed twice again


This indicates a short happened somewhere in the set, causing the set to go into "safe mode" where it won't let itself turn on. Oftentimes it's the convergence board. Depending on what that will cost you, you may want to just replace the set.
