Objective
This technical guide was prepared with the following objectives in mind:
• Provide the servicer with a brief overview of the concepts of operation for new
circuits employed in this line of models
• Provide drawings with emphasis on the signal path to simplify the task of signal
tracing and to locate the cause of a defect
• Furnish troubleshooting procedures that contribute to a expeditious repair of the
product
• Provide examples of typical problems that may have occurred in similar types of
circuits
• Provide updated information about changes reflected in the newer versions of LCD
High Definition TVs. The TC-22LR30 LCD TV /DVD Ram combo is basically a TC-
26/32LX20 model with the addition of a DVD Ram.
The DVD Recorder that has been incorporated in the LCD TV High Definition Combo
unit is basically the same as that of the DMR-E65.The equipment used for servicing the
DMR-E65 is same as the one used for servicing this model’s DVD-RAM Drive .The only
difference is that the DVD Recorder (DMR) has been downsized to a physically smaller
drive.
