I have a UA40EH5000M samsung led tv. Suddenly the screen went blank. only sound is there, no display. Which part may have the problem..please suggest..
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
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.
try connecting tv to cable direct also try unplugging both converter and tv for wile like 5 mins plug both back in see if tv and converter sync, but if otherwise then The ysus board is the most common reason. you can try websites on ebay.com to buy parts for replacement...
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.
ya, sounds like a bad light engine, but first i would check all connectors to make sure they are seated correctly.
this could cost you alot of money!!!
you need to call 1800samsung
if you talk to them and sound upset they may just fix it or replace it.
good luck
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.
