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: Blank screen, cannot get menu to display, but sound works

Does the lcd screen have a glow to it ? Or is it really dim if u get real close to screen u can see images moving ?
it it has a glow to it you panel lighting is fine but you control board is bad. If you have a dark screen and see faint images you panel back lighting is out u can check the power with a meter at the connection to inverter board on panel.

I think you need to exchange the Main Board.

Actually the Samsung model you have was the first model to come out in 2006 that did not have a color wheel. The LED blinking is actually a self diagnostic program of sorts. Depending on which lights are blinking, and how often, the service manual will tell you where you should start checking or replacing parts and assemblies. I do have most of the codes, so can you tell me if the if the LED light is the only one flashing, how long it flashes, and do any other lights flash at all? Thank you.

My samsung led tv, when i turn on red light blinks 6 times. no display, no sound. Tried replacing power board, main board and tcon board, all of them seems to be fine. What else could be the problem.

You have at least one bad LED in the panel and its shutting down the power supply...for future reference a bad Tcon will not cause loss of sound only affects picture

I have a Samsung TV with sound but no picture.

Hi James,

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.

Good Luck.

I have a Samsung 32" LED tv model number UN32F5500FXZA. It has sound but no picture but passes the flash light test. I don't see any backlights. Any idea what the part is?

The backlights are located around the edge of screen inside the tv. Now this model is know to have LED failures. The LED strips are you backlights. The LED strips are powered by the power supply board but due to the fact that this model is know to have LED failures, I would recommend replacement of the LED strips, all of them, first.

Samsung monitor 2232bw plus backlight fade in black backgrounds scenes

Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once.

If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: and follow the steps how to repair back light LEDs: Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...
