I have this model TV Mainboard is: 3647-0252-0150(6c) At first the HDMI devices stopped displaying and the TV showed this error "This content requires HDCP for playback. HDCP isn't supported by your HDMI connection. This content requires HDCP for playback" or something similar can't quite remember now. All HDMI ports would give the error when moving the same device from one port to another. Tried all the usual, new cables, TV reset, Devices reset, etc. with no success. So I bought some HDMI Port splitters from Amazon which generate a HDCP 2.1 signal which made each device work again. All was good for several months then last week the dreaded "No Signal" on all HDMI ports. The TV still works other than that, Antenna Tuner, the composite port which is where I moved my satellite box to be able to watch it.
My question is: Since all HDMI ports are equal in the error, what chip, solder connection etc. could I focus on/replace, etc. to attempt to fix? I noticed each HDMi port has a small EEPROM - ATMLH948 and they seem to terminate to a P130HDMI chip. I see a a lot of EEPROM's being sold online for TV fixes none really saying HDMI as one of them. I have bench experience, a converted toaster oven as a reflow oven, SMD air station and routinely build small SMD projects and am capable of replacing most SMD components. Can anyone direct me with some ideas as to what the issue could be please? I've fixed many a TV over the years but have never run into this particular issue before. I think I could fix it with a bit of direction. Anyone?
Thanks, Kelly O'Connor
