If I get a good replacement BN94-01442A board should it work regardless of the firmware version the TV set has?
BACKGROUND: I have a Samsung LNT5271F LCD TV that has the MISC FRC BN94-01442A board assembly going out. After warmup both vertical and horizontal lines show up in the display screen. At first it didn't occur very often and was very sensitive to mechanical vibrations (tapping on the plastic TV case would clear up the lines and return to normal operation.) I verified that it was the BN94-01442A board by blowing a heat gun on one of the large IC's on that board; heating the chip up brought on the problem and when heat was removed the problem went away. I think there may be a bad solder joint on one or more of the pins on the "ball grid array" under the chip on that board. Anyway, I purchased a replacement board on-line which had the same look and part number as the board in the set, but the replacement board didn't work at all; the screen was black with it so I returned that board and put the original one back in. In the mean time the original board has gotten worse and needs to be replaced.
QUESTIONS: 1.) Is there firmware in this board and, if so, does the board firmware version need to be the same version as that in the TV set? At first I thought the replacement board I purchased was simply defective but then I wondered later if it may have been a firmware compatibility issue that didn't allow the replacement board to produce a picture. I do remember updating the firmware to a later version in the TV about 6 months to a year after I purchased it.

My LN-T5171F was getting High Def channels but not any longer
When I first hooked up my tv, I was getting about five high def channels but I suddenly stopped getting them. I am on basic cable so I really don't know how I got them to begin with unless there is a built in tuner. I have another high def TV that is still getting the HD channels so I know the cable wasn't changed (or whatever the source is...). Is there a reset feature I can select to get it back to the factory settings?
Tv model is: LN-T5271F Bought in December 2007 Screen started flickering at turn on time (flickering went away after few minutes) This has been going on in September 2008, I did not worry about it I figured I can wait few minutes Today, the flickering started as usual However, it has been 3 hours, the flickering is still there. The flickering is at the bottom right hand corner of the screen. Please help. Steve
