I have a samsung television that turns on and displays a picture but the picture is pink and green. I'm thinking the main board is going bad, but they are pretty expensive on ebay. Is there a component on the main board that I could replace?

Re: samsung LN40530P1F image is pink and green
Take some photos of your boards on the inside, my guess it's going to be an AUO Optronics T-con with an AS-15 gamma chip failure.
Also you seem to be missing a letter between 40 and 530. -

Re: samsung LN40530P1F image is pink and green
Yep, another bad AS19 (similar to AS15) GAMMA IC U7, I hope you do have tools to do SMD repair.

You can verify by checking and report the DC Voltage readings on the test pads of GAMMA Voltages from 1 ~17.

Re: samsung LN40530P1F image is pink and green
#3, #4, #7 are bad, the numbers should gradually go up.
tom66 has spread sheet that you can fill in the numbers and see the graph, I do not know where that thread is right now.Last edited by budm; 11-13-2014, 05:20 PM.Never stop learning

Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;
I have Samsung Smart TV UA65MU6100WXXY version DA01
Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months... -
hi
having problem with samsung ua55es6800
tv had backlight on, sound working - responds to the remote control but no image.
check tcon board - had 12v in but no other voltages present.
when disconnected left ribbon cable - got back voltages and half image with lines and distorsion
when leaving only left side connected - again no voltages and no image.
put a tape on all (cd?! lines) on the left ribbon cable and got complete but distorted image (horizontal lines).
kept trying to block less pins on the left ribbon cable... -
I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time...
