AgentX20 Okay I've checked and mine is an A04, which is good for quality, but I'm wondering if it is best for screen sensitivity. It's quite a bright panel even at 0 brightness. What versions does it say on the second smaller label on yours? And what's it say on the service menu? (turn off, hold menu+"+" then press power, press "-" when on). Mine's V1B29, HN213.
I found the following details for the panels in each version on a site. It appears they changed to a quite different panel for the A03 and A04, so if yours are the earlier version I might get one to try also.
A00 - V1B11, LTM240M2
A00+ Interim update - V1B15, LTM240LM2
A01 - V1B15, LTM240L2
A02 - V1B15, LTM240L2
A03 - V1B20, HN208 (I believe there's a HN213 here too)
A04 - V1B29, HN208L6
