Hello bad cappers
I have been given a sickly LG 37LD490 with a glitching/tearing picture that improves as the tv warms up, but never quite clears up, also the HDMI ports don't seem to work. It powers on fine, gets past the LG logo to the spinning LG cube, you can enter the menu, etc, although I don't have the remote
The power supply output looks like this;
NC | Error
12v | P-Dim
12v | A-Dim
12v | INV ON/OFF
Gnd | Gnd
Gnd | Gnd
3.5v | 3.5v
3.5v | 3.5v
Gnd | Gnd
Gnd | Gnd
20v | 20v
Pwr On | 20v
The 12v output is running at 12.3v, the 3.5v is at 3.4v and the 20v is 21v. My assumption here is that is in reasonable spec. No visibly nasty parts, everything looks "normal". Attached are pictures of the three main boards and my furry diagnostic assistant.
I gather from googling that re-flowing might be in order? Any tips gratefully accepted.
Thanks.
