Re: LG 50PH670S no video only audio
because if I let the current pass I hear a noise and when I remove it I find it interrupted. he also has oxide. I wanted to change it but I don't know what values it has. looking on the internet I can't find the number written aboveLeave a comment:

Re: LG 50PH670S no video only audio
I disconnected the flat cable because on the contacts of that flat it gave me continuity so I assume that one of the two buffers is shorted and I tried with the disconnected one if it turned on the screen after which I stopped and asked on the forumLeave a comment:

LG 50PH670S no video only audio
hi everyone i have a problem with this plasma. At any moment the video is no longer visible and only the audio is heard. Is there anyone who can help me? i turned on the tv and noticed a hum on the ysus and the heatsinks are all cold on both ysus and zsus. The voltages vs va are all correct. Disassembling the buffer board there is an integrated in short circuit because it is in continuity. Thanks for the help -
