DOE Proposed Rule 

Power Consumption Standards 

For Televisions 

Prepared by D. Traver 
Outline of Arguments Against

Acceptance of the Standard

• The Standard is based on incorrect assumptions

• Rebuttable Presumption requirements are not met

• DOE Technical Support Document incorrect

• Industry had no input into Standards Setting Process

• Combined features are energy efficient 

• "Most Technologically Advanced Set" - is not 

Prepared by D Traver 
DOE Technical Support Document

• The Document content is Incomplete, Inconsistent and

Incorrect in engineering approach.

• Sample Selection - Old Product, Selection procedure

questionable

• Product Classification incorrect

• No data is provided. How can we calculate efficiency?

• Energy Efficiency is not properly addressed

• Design Option assumptions incorrect - Must include CRT

System, Standby Power, Power Supply and Features

• Invalid Power Supply Assunlption On Stereo Effect on

Power consumption

• Po,"'er Supply Efficiency and ability to perform in wide

operation range of mains must be included

• CRT System Power Supply needs must be included

Picture Quality - Deflection, Contrast, etc.

DOE Design Options:

White / Black Level

• The DOE measurement is of basic CRT Systelns

• Manufacturers can defeat DOE over shnplifted Standard

methodology by adjustment and/or design

• Picture Quality has a direct relationship to power

consumption but not measured:

Contrast Brightness level

Color Accuracy Safety - Glass thickness

Geometric accuracy Resolution

others.
