My samsung LE40R74BD set works fine for about 10 mins then screen goes blank (black) . It would appear there is no back lighting. I have visually checked the psu for blown capacitors but all seem to be...


This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

Turn on laptop, loads fine, screen comes up, then screen goes black. computer is still running and you can see it if you put a flashlight on, but screen remains black.


Try to adjust the back-light on the screen by pressing the FN and UP arrow to increase the light.

If that does not work then it means that your back-light on the screen has either failed completely of works for a couple of minutes and then it goes off. You need to have your screen replaced with a new one.


Sorry for the bad news.

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

Hi pdooley1, I will be happy to help, We need to check the backlight, the easiest way to do this is, 
  1. Turn tv on to a point you have sound.
  2. Take a flashlight or a lamp with a bare bulb and shine it on the screen.
  3. Look very closely at the screen and see if you see a dark video image.
If you can see an image you have a bad backlight inverter. let me know what you find and I can assist with replacement. Please rate this solution. lone99star

My monitor works for a little while, then goes black.


Your power-inverter board needs an overhaul.
Probably in need of the standard capacitor replacement.
OR
a bulb in the screen is bad (a bad bulb will usually show symptoms)
It will flicker, or will look pinkishish for a bit or dark in the middle top or bottom of the screen.

Screen gone black


Sounds like the screen inverter may be going out. The only real way to check it is replace it or take it to a shop and have them test it.
