Summary: I just finished writing a review on a GT25 which had stopped working after 2 years (power supply with the red flashing light). I happened to have this model ST30 in a box having bought it in November 2011 for a rec room which still hasn't come about. We unpacked it, put it on the the wall mounts and hung it and hooked it up. Pushed the power bottom and a loud buzzing with no picture. Messed with the cables and still nothing.
Summary: Before I purchased my TV from Amazon I first went to my local Best Buy to see the problem for myself. I figured that since everyone talked about how bad the brightness problem was, I should be able to easily notice it in the store. To my surprise, the image looked great! So, I ordered my TV from Amazon (almost half the cost of Best Buy) and received it a week later only to find out that the TV kept changing the brightness for me, as described here and elsewhere.
Summary: I Researched HDTVS for about four months. Compared many models plasma vs led, and went with the st30, because 1) The pricepoint 2) the overall quality. I recieved the tv in great shape, broke it in 100+ hours and must say, the picture quality, level of blacks..are just incredible. The quality is top notch. But, as time wears on, the defects are now showing, more and more. I have green tint/blobs (not calibration issues) which I can live with. BUT.
Summary: I decided to go with the ST30 after recommendations from several sources on a new TV. I spent well over 100 hours running break-in slides and then calibrated the tv using the D-Nice settings. When I first started using it, I was blown away by the picture quality and thought I had made a great decision on a new TV.
Great PQ, but HORRIBLE (delayed) brightness fluctuations
4 July 2011
Summary: To preface this I have had 2 P50ST30s (one replacement because of the problems I will talk about below) and Amazon was awesome with the whole return and replacement. One of the best companies I have dealt with. This is a very long review as I would like you to understand what you are buying beforehand. ALL VERSIONS OF PANASONIC 2011 TVs ARE EXHIBITING THIS PROBLEM.
Summary: Just got this home and ran it through calibration process. The image is stunning. Buyer beware though-this model and apparently all other 2011 panasonic models have a fluctuating brightness problem. almost every shot changes the brightness of the picture, and often, even in the same shot the brightness flickers. Also the green hue comments are spot on. I followed d-nices settings specifically and still have a ton of green fringing and shading.
