Bought this TV last Dec. 31 at SM Makati and I'm about 50 hours na sa break-in using the 120v slides, HD movies and ps3/xbox gaming.
Nagbasa-basa din ako dun sa official PK550 thread sa AVS Forums
http://www.avsforum.com/avs-vb/showthread.php?t=1235720&highlight=ea+programming&page=152 , so far positive naman ang feedback sa plasma model na 'to.
The only concern which I discovered with this model e walang Expert Mode options sa Picture settings compared to other similar models outside the philippines. Meaning di ka pede mag tweak beyond the Basic and Advanced Picture settings... di mo ma access ang Expert Mode calibration. Tumawag na ako sa LG ph tech support at ang feedback e the firmware is different which they cannot change here kaya no choice.
Pero over-all, I'm happy with this tv, no noticeable input lag sa mga game consoles particularly sa Xbox although as per experience nun mga nasa AVS, you need to use a VGA cable for the xbox para mas fluid although I didn't notice anything using HDMI... HDMI cable is also ok for the PS3.
On HD movies, out-of –the-box, PQs are great, blacks are blacks and the colors are stunning already for my perception using only basic settings. I can't run on optimal settings kasi break-in period pa lang. Pero ang sabi sa AVS the more that I reach the desired 200 hrs break-in period e mas gaganda pa ang PQ which I believe is common for plasmas…. then I can calibrate this as desired.
IR's are common for now dahil bago pa pero if you enable the built-in orbiter and run the color-wash and white wash function after watching, the IR's does go away after a few minutes. Screen reflections will be a problem for some na meron direct background light facing the TV but if you can fix your lighting, this won’t be an issue.
Just an advice lang sa mga interesadong bumili nitong TV model na 'to... please bring a USB flash disk with a loaded v120.1 slides which you can download here at
http://www.webapalooza.com/plasma/. Plug the flash disk at the left side of the tv then run each color slides. This will then help you identify right away if there are dead pixels off the box of the unit you are purchasing. I’m sure most of you are familiar with this method, just sharing to those who are not.
And if you have finally decided to buy this TV and once you get to set it up at home, you may use the same v120.1 slides to break-in your TV with the following settings…
1. Use one of the inputs preferably the component
2. Settings: Cinema (User) – to be used only for break-in only
Speed setting: Slow
Contrast: 100
Brightness: 50
Sharpness: 50
Color: 50
Tint: 0
Color Temp: 0
Gamma: Medium
Black level: Low
3. Any type of "enhancements" should be turned off.
I’ve learned that if you use these settings for the break-in, this will help the phosphorous mature much better.
Normal usage should be set to normal Cinema mode and always watch or play with the orbiter on, to avoid IRs.
I have saved countless of optimal settings but will only be applied once I graduate from the break-in period. I hope the other PK550 owners here will share their best Picture Mode settings so I can learn from them.
Again, I have learned these options after reading more than 150+ pages dun sa official PK550 thread sa avsforums.
I think this is my first post since I joined pinoydvd last Jan. 2, 2008. lol
Hope this helps.
