Hi All,
I have this 30" LG display, its story is as follows:
- worked flawlessly for 4 years, then a 200 pixels high horizontal band on the bottom of the screen started acting funny: it would freeze, then slowly become washed out, then black.
- had it repaired by an official LG shop, they changed the logic board and it worked fine again for about 1 year. A thing I've noticed immediately is that after the repair, while disconnected from a signal, it would cycle red, green, blue, white. Beforehand it would just stay black so I think that they have changed something, in fact.
- some days ago, it started producing black flickering random lines/garbage from around 2/3 of the screen height down to the bottom.
Along with flickering, I get very fast tilting and portions of screen copied around randomly. The defect is there even if disconnected from a signal.
The defect seems to be heat related as it works fine for a while (30 secs - one minute) when turned on from cold.
I have already replaced all the caps I could see on the PSU board and signal board...except the two with a red dot on the PSU.
Note that I think the first LG center swapped my psu with another as it hat 2013 written on it while the monitor was purchased in 2009
what should I look at now??
Many thanks!!
