Question about Televison & Video

1 Answer

I own a Samsung ln40b530p7nxza tv. I came home Saturday night to and when I tried to turn on the set nothing happened. I made sure the batters weren't dead in the remote by using the power button on the tv... It has power(the red light in the bottom right corner is lit) there is a pausing humming sound that I haven noticed in the past coming from it. Prior to Saturday night I haven't had any problems with the tv at all...

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

SOURCE: Tv won't turn on

I had a similar problem when there was a power outage or the lights went briefly out. I unplugged the TV and left it for a few days/weeks and then plugged it in and the TV worked. I think newer TVs should be treated like a home computer and put them on surge protectors.

It seems to respond to power supply, send it to a nearby technician. The problem might be it fused the picture power supply fuse. make sure the installation is at you presence.

SOURCE: AKAI 32" LCD HDTV WILL NOT TURN ON

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

I have a 2004 montecarlo ss the headlights turn off while driving at night sometimes for a second or for a couple of minutes.


is it while you are using your high beams, my is doing the same thing, tried wiring a toggle switch to suppement the turn/wiper stick instead of buying a new one. Worked great until i activated the momentary high beams while the switch was in the high beam position. Then power was cut to the entire car. Its like there was no batter. Can't find a single popped fuse or bad breaker, and the batter is good. Not sure what happened, according to the hanes maual i was wiring in accorance with, nothing should of happened like this.

Could be serious...but first check the screen modes (for split screen, format, etc) to be sure the tv is set up properly for the picture you are trying to watch. Switch the input to a DVD or something similar. Is it the same? If not, you have a mode/resolution problem with the tuner and perhaps some other device.

unplug. leave off for a few minutes. small chance it will reset.
