It might be as simple as the fuse on the doubler board.
If you are capable of TV repairs, inside the TV, where the power cable connects to the board, there should be a small glass fuse. Check that to make sure it is not open, if it is, try replacing it with the same amp and voltage, if it pops again, then it is something more serious like a short some where.

Tv problem help


With the plug from the t.V. unplugged from the wall outlet, remove the tv cover. Follow the power cord to the power supply's printed circuit board. Look to see if there are any damaged, bulging or burnt out (exploded) capacitors. If there are, that's the source of the problem.

Be fore warned, even though the power cord to the tv has been disconnected from the wall outlet, good capacitors still hold (store) hi-voltages that can shock & even kill you; so don't touch them unless you know how to properly discharge a capacitor. Don't underestimate the power that these components store even though they are very small.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

RED LIGHT FLASHES 10 TIMES BUT WILL NOT TURN ON!


There might really be a problem with the unit. Try unplugging it out of the power outlet and plug it back in after 30 seconds. If your using a power box (voltage regulator), try plugging it directly to the outlet. If all nothing happens, see a local tv tech in your area. The unit could be damaged.

My tv shut down and wont turn on


If you are certain you have power at the outlet, try plugging a lamp into the outlet and see if it lights up, then you may have burned out power supply

The TV will not turn on.


I have the same problem, push button to turn on tv but it only does a click like it is going to turn on and then another click bit it wont turn on. Finally a red light is just blinking.

Any suggestions, is there a freeze button or code that I need to push.

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT

TV won't turn on


When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.
