Re: LG 60PM6700 no picture no sound

My pals diff and Unspun01 nudged me to recheck cables. So, after carefully reseating the flex cable, the set appears to be functioning. Thanks again for your replies!

Re: LG 60PM6700 no picture no sound



Thanks for fast replies! The Model was incorrect....it is a 60PB6900-UA. The replacement main boards have identical screen printed identifiers across the top starting with PU42A and the part number is EAX65399305. The first new replacement came from abcaGroup and they claimed it was new and offered to send another if I returned the first...which was done. Neither new board brought back picture or sound. I am double checking cables. Voltages coming in from the top of the circuit assembly match the labeling, but I will double check....

Re: LG 60PM6700 no picture no sound



This was a great hint. I have good test patterns using this test technique. I have swapped the main board with new assemblies...twice. No picture or sound with the original or either of the two *new* replacement main boards. Searching for another clue for where to look for the issue(s). Sure seems like it is external to the main board but somehow related. Perhaps somebody has come across another defect which would kill the picture and sound but not be on the main board? This is a 65PB6900....
