Hi Dustin,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

    Thanks for the information, I would prefer to try and fix this myself if I can. Also it is a plasma and it doesn't flicker or anything. I turn it on, the power button flashes, the screen briefly shows grey and then goes completely black. It does not shut or power itself off and it also has no sound. I'm assuming it had a power surge and something got screwed up, however I have checked the TV for swollen caps or anything that looks like it was burned or scorched and everything looks like new. Any other suggestions? Thanks again

My Samsung TV won't turn on


Please describe the problem more accurately. Flashing red usually means 'stand-by' state, flashing blue/green - starting up. When (during that) do you have a sound? Are there any 'high voltage' sounds like soft screeching from the screen? Is it LCD or LED?

When I turn on the TV the blue indicator light comes on but there is no display, then the blue light starts blinking.


The following steps should be able to correct the problem:
1) Unplug the TV or remove AC power from the TV
2) Count to ten and then plug in the TV
3) Locate the [Menu], [VOL-] and [Power] button on the TV’s side panel
4) Using the buttons on the TV’s Side Panel, press and hold both the [Menu] and [VOL-] buttons.
5) While holding those buttons, press and release the [Power] button one time and count to 3 before releasing the [Menu] and [VOL-] buttons.
6) The TV’s lower left Blue Power LED will come ON.
7) Wait 30 seconds. Confirm that the blue LED on the Lower Left of the TV (not the iPod dock for iPod models) has remained ON during this time.
8) Press the [Mute] button on the TV remote twice
9) Unplug the TV or remove AC power
10) Count to ten and plug the TV in
11) The TV power should automatically come ON and the blue power LED with be ON
12) Wait 40 seconds and the TV picture should appear
13) You can now continue using your TV.
14) If the picture does not appear, power on the TV manually:
· If the LED begins flashing, unplug and power ON a second time.
· If the LED begins flashing again, power ON the TV without unplugging
If the LED begins flashing again, contact us directly by phone to obtain a local authorized service center for you.
If the TV does power on, please reply back with the software version number for us to research this issue. Please follow these steps to obtain the software version number:

1) Press the [Menu] button on the remote control.
2) Using the arrow keys in the center of the remote, scroll over to the "settings" menu and select the [OK] button on the remote
3) Scroll down to "system info" and select [OK] button on the remote
