we have a 42" Samsung led and today when we turned the tv on one half of the screen was black and the other half blue we could here the sound but no picture available only the day before it was flickering a little the tv is 2.5 years old
leavingledge acing over night re plugging all wires and hd cables bak in
Can you please get me the model number off the back of the TV?
Additionally, what is connected to the TV for devices (DVD, cable box, etc.), and do you have the same issue regardless of which INPUT you select?
If you bring up the MENU on the TV, is the MENU clear and visible over the Black or Blue screen?
we have a Samsung blueray DVD player and a sky hd box connected however these all work on our spare hd led tv, you could not see anything on the left side of the screen however on the right side through the blue you coud only just see something but nothing clear and the screen is a 50/50 split with black on left side blue on right, no matter what we did on with control you couldn't see anything ie sound menu etc
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the setback in and press power once. Do you still have the same problem?
we have pressed the screen this is not a button but it's the power on of symbol that is activated by touch turned the tv back on and we still have the same problem
There are basically three problems that would cause this, the Power Supply,the T-Con board, or the LCD panel itself has failed. Voltages need to bemeasured at the power supply outputs, using a DMM with nothing connected to itbut AC Input. If the readings are proper, then the other boards need to beconnected one at a time, until one causes the voltage to shut down at theoutput. Price to replace the power supply is around $200 parts and labor. Ifthe supply outputs power with all of the boards connected, then the T-Con needsto be tested. The T-Con will run you around $150 to have replaced. If the T-Contests good, then the LCD Panel has failed and will cost you more than a new TV(around $700) to have replaced and it is not cost effective to repair this set.I wish i had better news on this set, but the symptoms you're having indicate afailure in one of the components responsible for powering, and processing theLCD panel itself (including the LCD panel).
If you do not have experience testing live voltages on a circuit boardlevel, then I would suggest using the link below to locate a tech in your area:
the tv is led not LCD does this make a difference
An LED set, is an LCD panel that is backlit by LED lighting instead of CFFL (flourescent) lights. The issues, and problems that the sets have are the same.
