Howdy all...My JVC TU-42WV74 is showing what you see below.
When the image to be displayed is midtones to shadow, the picture is wonderful. When the image is mostly white, such as on the end of those apple commercials (all white screen with the logo in the middle) the defect shows.
I have the service manual, entered the self diagnosis mode, and found the following codes:
XRAY OK OCP OK
LOB OK TIM OK
SYNC M:OK S:OK HD:NG
MEM OK AVSW OK
VCD:NG9
AIO OK YC OK
TUN OK GCR OK
PP OK IP OK
HDMI NG9
How I read this is that VCD ng:9 is my issue. (Video Chroma) Yah?
The service manual refers to "IC301", and I trace that back to the display interface board.
does this seem to be a logical connection?
Thank you tons...
