Main Board 791.02410.0003 (with LWZ2VWAT Serial). Removed From A New Cracked Screen TV. Before ordering replacement parts please take the time to verify part numbers from the old part. This can only be done by removing the televisions back cover, don’t rely on suggestions. DO NOT use only the model number since there are numerous versions and all use different parts. Order by the exact alphanumerical sequence found on the old part you are replacing.
