Re: Samsung Model LN52A550P3F only displays half a picture

Update on LN46A530......Sorry for jumping the thread, but the problems almost alike........

Ok, must have have 3 issues :

First, the LVDS cable must have been dirty, I got improvement by cleaning with a small soft paint brush and acetone ONLY on the connector pins. Cleaned all the connections to and from the main board with the acetone.

Second, I had changed to ribbon cable also. and

Thirdly (is thirdly a word?) anyway, I put some insulating foam under frame on...

Similar issue..LN46A530 left side blank. Cleaned LVDS cable, connections and ribbon cable connections to driver boards. Problem changed to good Left side video that flickers to vertical lines and back to good video in 1/2 to 2 second intervals. Also, left side take 1 second longer to pop into view. Plan is to check voltages in and out of main and tcon. Any suggestions? Test points?
