Hi everybody,
I've got a problem concerning my 2year old Samsung LE-40A616(A3F) LCD TV.
I've have a ferm background in electronics, except it's my first LCD TV that I have to repair.
I've googled but can't seem to find any usefull information nor the (free)service manual...
Symptoms:
To problem is that sometimes the pictures is double displayed,
it's hard to describe but you can see it in the picture.
This problem occurs with all inputs (TV, Dig TV, HDMI, D-SUB, etc...)
First this problem occurred when turning or the TV.
It resolved itself after 5min. After 2 weeks I shook the TV
and the problem was gone...
Now I can simulate the problem just by slighty pulling the upper left
corner towards me while holding the other corners steady.
So I thought it was connector problem....
Things already done:
1. Disassembled the PCB's, including the ones that are fixed to the LCD Matrix and inspected them visually. I see no problems.
2. Disconnected and reconnected all cables, including flat cables and inspected them visually. I see no problems.
3. I've disassembled the Power Supply PCD (Middle) & Motherboard (if you can call it that way)(Right). Afterwards I've put them right next to the TV and connected them.
Next I've disassembled the T-CON PCD (Up) and put that on a bench right behind the TV. I can still simulate the problem...
So this means that these PCB's are OK. (Power, MoBo, T-CON)
Personally I think it's a problem with the PCB's that are fixed to the LCD matrix or worse,
a problem with the LCD Matrix itself.
I'm out of options, maybe you guys can give me a hint...
Thanks in advance, Nick |

Nick, you are not alone! The image on this TV went double!! I have disconnect ALL inputs; updated to the latest firmware; reset all of the factory settings; checked, cleaned and secured all wiring connections; replaced the T-CON board and for about 20 seconds after turning the TV on "cold," the image is PERFECT (before T-CON replacement, image was always double), and then gets progressively double. Has anyone seen this? Any solutions? See here for an image of my picture (post#3770).
