I'd start with checking the power supply output voltages. Also, the LTV32W1 appears to have solder joint issues, so I'd closely look over the board; specifically, I'd check the primary side of the PSU for your LTV32W3: https://www.badcaps.net/forum/showthread.php?t=9360
It might be helpful to upload clear pics of the front and back of your actual power supply.
It might be a good idea to include at least one pic of the TV's whole circuit board layout, also. Unless there's some weird anomaly, it's fairly obvious that the issue lies in the PSU, though.
