LG 22MT45D-WS
Horizontal stripes/bands, medium greenish, random, changing place. External power supply dropout filter capacitor. 1,000uf /25v. It seemed like bad contact on the LVDS cable and sometimes even on the internal tracks of the board. I looked through everything on the TV, replaced the lvds flat, etc. In the end, the problem wasn't even with the TV itself, but with the external power supply. When I turned it on with the bench power supply, the TV turned on normally. observation: when measuring the capacitor mentioned in the previous field, with the capacimeter, it was fine, but when measuring the power supply output with the oscilloscope (with load), it showed noise, without load it did not.
