When the red light is on, can't you turn it on by pressing channel up on the set, or power on the remote? If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Its possible that a capacitor has gone bad. You'll need to work on that, and then readjust the set. Not a major repair. When you open it up look for dry soldier joints and resoldier if necessary. good luck

Samsung TV (model UN40H6203AF) 40" LED. No picture, have sound. Flashlight test can see faint menu screen. Have replaced power supply & main boards to this point. Ideas as to what to do next?

Hi Terry,

If you can see the faint picture in flash light means the power supply and the main board is working. The real culprit is the backlight. Even one bad LED in the backlight will switch off the whole array. To repair this fault the panel has to be opened and the defective LED or LEDs are to be replaced.

This is a complicated, delicate and risky job and must be attempted by an expert only. You may end up damaging the screen permanently if you have not done it before and try to DIY.

My 2007 Land Rover Freelander makes a whistling sound when vehicle is idling. Sound goes away when accelerating or applying petrol?

it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck
