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.

You need a fluorescent back light and inverter kit. Available on eBay.

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.

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.

Screen is black but I can hear sound.


Most likely the power supply board needs to be replaced. It could also be the backlighting. A few TV's have a separate power board just for backlighting, but not many.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

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: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...
