However, on initial viewing, it appears that I have sacrificed a bit of PQ, but the trade off is worth it to me. I must add that Samsung customer service has been awesome and has really gone the extra mile to make customers happy and resolve this issue. |
I just had the projector assembly, digital board and power supply replaced the other day in my HLM 507W (now a 7/12/03 302 board), and noticed similar PQ issues, which went away by going into the service menu and changing the Gamma from 4 to 0, as others have suggested. It made a huge difference in the Grayscale ramps (no blown out whites) and better overall PQ (no compression artifacts). Also I noted that the tech had instructions from Samsung to change some of the settings from the new board to match the old board ( Fan number should be 2 on 43" and 50", Delay should match previous board (223 on mine), and lamp should match new bulb (Tosh/ Phil for 50").
I also ran DVE on it and netted out with Warm 2 for component 2 (480P DVD) (warm 1 for Comp 3 HD) but identical settings as follows...Cont 100, Brit 53, Sharp 0, Color 72 (which seems high but that's where it netted out)...note I have a RF variable attenuator on the DVD component Red Cable (Radioshack part # 15-678) that balances out the red push on my Panasonic RP56 player (using the color decoder pattern on AVIA)
