I'm a user of P42X28K and I dunno much about LG 42PQ30R in terms of Picture Quality (PQ) when comparing side by side. I believe both are about the same
in terms of specifications. No distinct specification difference. However, judging from appearance, one may prefer the former over the latter or vice versa, and this could be from the overall design that may capture one's attention.

If you want to really know the outcome, then compare both side by side with source from Bluray and Astro, then you'll probably find the answer you are looking for. You may also want to research abit on after sales service to help you to nail your decision.

As for the former model, P42X28K, the base stand now is swivel type where it can be angle about 15 degree on either side. This is not available on previous X series. Sound quality is mediocre, nothing to shout about. Normal volume setting is around 30 -32 with viewing distance approx 9 feet. And 80% of the viewing time is on Astro
Byond, then remaining time is a mixture of DVD and PS3. However, there is a difference in PQ for Astro Byond box and the normal box and I believe it could be the HDMI vs the RCA.

so what say u?
LG or pana plasma??
hehe

ehm.. itching de..

I am glad to hear you are very happy with your TV.  Hope you will enjoy it to the fullest.

I am using the P42S10K bought in Dec 2009.  What I did was to set the brightness & contrast settings to 50 with eco mode off & watch whatever with these settings for the first 200 hours. 

Exceeded 1000 hours already.  So far no IR/Burn-In problem whatsoever. And also no deterioration in black level whatsoever.  Black is as black as it can be.  After watching for the day, will "wash" the screen for 30 mins (timer set) & to auto shut off.

Thanks

# Hold down the {VOL -} button ON THE PLASMA TV itself. Not Remote
# Press the {RECALL} button on the remote control 5 times.
# The Service Menu will be displayed.

# Use the {2} buttons to select "SRV-TOOL"
and press the {OK} button to access it.

# HIGHLIGHT the box on the right side of the last option: (Navigate by using the arrow buttons on the remote)

HIGHLIGHT HERE

# Then press and hold the {MUTE} button on the remote for 3 seconds.

TIME = Hours and Minutes of Operation.
COUNT = Times the Plasma was Powered On.

# To exit, press & hold the {POWER} button on the TV for few seconds.


The above for going into the service menu & checking the hour usage.  Please be very careful when you go into the service menu.
What I do for "washing" is to press the TV button on the remote.  Since I am using Astro, the outside TV aerial is not connected.  So if you press the TV button on the remote, there will be no input signal to the TV.  The screen will show a snowy picture.  Set the Timer (max 90mins).

Thanks
