I had an RCA L32WD12 LCD HD Television set that would occasionally exhibit a problem that looked like a kernel panic on a Unix computer.
When viewing channel D3-1 (Tampa) and pressing the "Info" button on the remote, the information window would first appear but the screen would immediately be flooded with white text. At that point, you could still see the picture being updated behind the clutter, and hear the sound. However nothing else would work. You couldn't change channels or turn off the power.
The only escape was to unplug the set. Plugging back in after a few seconds, the set would come back up in the "on" state. After the usual initialization, it would be tuned to Channel D10-1 (also Tampa), but the channel label would still be D3-1.
Afterward, everything seemed to be OK except that date and time had been lost. By changing the channel, channel label numbers were corrected. The Info button worked correctly on all other channels, but when returning to D3-1, the problem would recur every time.
Has anyone seen this before? Is it a correctable problem? If I were to purchase another RCA, is it likely to happen again?
