The explanations below are only for the LTA400HM04 coded panel. It does not work for different panels.
PROBLEM ------ > The picture flickers:
In
order to determine which side of the panel the problem originated from,
first remove the left film that connects the t-con card to the panel
from both the t-con and the panel and start the television. If the image
displayed on the screen is correct, the right side of the panel is
defective. If the image is the same, attach the left film to both the
t-con card and the panel, and this time remove the right film. If the
image improves, the problem is with the left side of the panel.
If
the problem is on the right side, cut the signals CKV1 and CKVB1, CKV2
and CKVB2, CKV3 and CKVB3 in two respectively. If the image does not
improve, also cut the STVP signal. When the picture is correct,
reconnect other signals except for the group of signals you cut last.
If
the problem is caused by the left side, you can cut the signals by
sticking a thin tape between the film connected to the t-con board from
the panel board and the socket to cut the signals.
If you place the LTA400HM04-left-Tape properly on the appropriate pins, the image will improve.
