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

I have a Samsung rear projection tv, the picture is faded and the colors are not crisp or clean cannot watch it like this what do you think the problem is?


If this is a CRT-type rear-projection TV, the CRT coolant fluid is probably broken down. It's supposed to be clear, but after a long period of TV operation, it turns a yellow-brown color. If you unplug the TV and remove the back, you can look into the tops of the three picture tubes. They should be a clear red, green or blue color, with no yellow-brown tint.

CRT coolant can be changed, but you need to be very good at mechanical work to do it. Besides the safety considerations (picture tubes and other parts may carry a high voltage charge even when the set is unplugged), spilling broken-down coolant on electronics is usually disastrous, so you have to be very careful.

LCD panels used in projector applications may lose contrast if they are overheated (this can be caused by failure to keep the vents clean as recommended in the owner's manual).

You would have to provide your set's model number to get more specific information.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Samsung 40 inch LCD LNS4092D No Picture


You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

When the screen goes blank, hit any remote function that will show up on the screen-like volume bar. If the display is missing as well, then you have a tv problem. If the volume display is there when the tv picture is not, you may require a software upgrade.
