TV Powers On, Sound OK, Half screen green while other half is good
Power, screen and sound work fine on my Samsung un65eh6000. However after cleaning the TV screen with fine (over)spray of Windex left half of the screen has now gone green. At first for like 30 mins after wiping, it earlier appeared smudged, then we saw some ghosty black snakes all across the screen, then the whole screen turned white and now the right half of the screen is all Green while the right half seems to be OK. I took off the back cover and panel etc.. and am now to the board level. The two cables from TCON board to the bottom of the TV have been disconnected/reconnected multiple times but no change. I did see some water droplets (must be Windex) at the bottom of the TV where a few circuit PCBs run that connect to the main screen with very fine band type cables, but i did blow them dry. Also, without any signal, the entire screen goes blackish/blue and I can see the hue light lit at the back. So the LCD is good. However the moment I connect the ribbon cables from the TCON board to the LCD circuitry that lies at the bottom of the TV, the left half of the screen remains black with the "No Input" text box displayed on the screen but the right half of the screen turns all green. I have attached a few pics with my post to explain the situation. Hope the pics give you a clear idea and picture of the above explanation ..
The 4th image from top was taken after I disconnected both the ribbon cables from TCON board to the bottom circuitry. As you can see that all screen turns black with a slight hue on the back throughout the panel, which tells me that the LCD/LED screen is still working good. Its some issue either with the ribbon cables or the TCON board.
The 5th image was taken after only the right (bad) side's ribbon is disconnected but the left side ribbon is intact. In that case I do see a small white line on the extreme right side of the screen, which was not there (as you can see in image 4), when both the ribbon cables where disconnected. I guess it may a result of the left screen info. overlap.
The 6th image shows the back of the TV when it is ON showing all 3 boards and the glowing light of the screen.
The 7th/8th/9th images are that of the TCON/Input Source/Power board respectively.
Any help / suggestion will be very much appreciated.
Is this a good question?
