My tv will turn off but will not turn on

I have a 40" flat screen tv, when you power down the TV it turns off but when you turn it back on the blue light flashes twice and does not come back on - if you unplugged the tv and plugged it back in it would then come on but that is not working anymore

Hi,

I am assuming that you are connecting the Dell PC to the Samsung 40 inch flat screen by VGA connector/cable.

Perhaps what might be causing no display in the Samsung FlatScreen is that the video signal it is receiving is beyond its capability. To correct this, pls:
1. lower screen resolution of your laptop's properties.
2. it may also be of help if you likewise lower the screen refresh rate.
Both of the above may be adjusted through the appropriate settings in your Display Properties of the Dell PC before you remove the monitor.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

Is this a tube television? If so, sounds like the flyback transformer is dead. Take it to the service depot FOR AN ESTIMATE!!!! It's probably cheaper to buy a new TV then repair the transformer.

Its unfortunately a bad LCD panel. Even though the warranties for these TVs has expired, you should contact the manufacturer because there may be a hidden warranty ( when a manufacturer knows of an issue with a limited number of TVs and decides to quietly take care of those consumers who contact them.)

Be prepared for some resistance from the first person you speak with. Persistance pays off when dealing with the customer relations dept.s of large corporations.

SOURCE: INSIGNIA LCD won't turn on

replace 2 condensers in the power supply with greater voltage ones.original are 1000uf 35volt...use 1000uf 65volt...99cents each
power circuit is made to fail with typical tv industry tactics...the warranty is reflected by the life of their condensors (capacitors) average life is 2000 hours..
easy...huh
if your a smoker...you must clean the button cover as they get stuck on with your stupid tobacco residue. 75% of all LCD tv's that smokers own fail this way...
\tough huh?

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

What does it mean when your 42 inch TV has a blue screen


The blue screen means that the back light is on. There is no signal coming to the screen to modulate a picture though. Also since there is no sound it means that the main pc board in the unit is probably bad.

Entire screen has a pink tint. Can change to blue with settings. Cannot change to natural with tint etc.


Check that all cables are intact and plugged in correctly.
Turn of the TV completely. There might be a manual button on the tv for this. As the last thing, remove the power cord from the power outlet in the wall or where it is placed. Wait 1 min. Then put it back in, swith it on and turn on the TV again.
If this doesn't help and you have tried replacing the cable that you get the picture from (VGA, DVI, Antenna etc.) then it is most likely broken.

Blank screen with blue light


Hello
Check the backlight inverter board to your TV. This is a common fault for most of the LCD TVs. If it is faulty, the backlight won't light up, resulting a balck screen with sound.

The whole screen turned blue while shifting it to get to inputs. Now I can't get anything but a blue screen.


If you have not turned the TV off yet then do that. Turn it off and let it power down completely. If it has a fan then let the fan stop spinning. Wait about 5 minutes then turn the TV back on. If you still see blue then you may need a new bulb or the light engine in your TV has gone bad.

Blank screen Samsung LN-R409D, audio when turning on and off and blue light at power button in on position???


Hi there
Im afraid this sounds like a fault with the TV. Try turning it off at the wall for 3 minutes, and then with nothing plugged into the TV, turn it back on. If the problem persists contact the manufacturer.
Hope this helps
