LCD TV’s are in a league of their own, since we have been working on the newer lcd panels several things you need to know about these sets. First of all component level repair is virtually impossible. The same set with the same model number may have different components depending on where it was made. In most all the manufacturers sets that I have worked with, the serial number range will determine the parts needed for a repair. In general the reliability of lcd televisions seem to be very good. Out of warranty repairs are more expensive because of the board level repair, some service manuals don’t even come with a schematic any more, just a block diagram so you can determine which board is the culprit. In the latest generation of lcd tv’s they have condensed the circuitry down in most cases to about 3 smaller boards.
