## DOE Proposed Rule Power Consumption Standards For Televisions

Prepared by D. Traver

## Outline ofArguments Against Acceptance ofthe 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

## 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 Prepared by D. Traver

## Design 

## Options: Standby Power

• Standby power is directly affected by features: 

### Memory - Channel, User Settings, Clock Ability 

### to sense Remote

## Design Options: Standby Power

• Standby power is directly affected by features:

Prepared by D. Traver Memory - Channel, User Settings, Clock Ability to sense Remote

## DOE Design Options: Power Supply
• Invalid Power Supply Assunlption On Stereo Effect on Power consumption • Po,"'er Supply Efficiency and ability to perform in wide operation range ofmains must be included • CRT System Power Supply needs must be included Picture Quality - Deflection, Contrast, etc. • Power Supply etliciency data by D()E not. provided

## DOE Design Options: White / Black Level
• The DOE measurement is ofbasic 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.

## DOE Model Assumptions

• Sample l\'Iarket Share not known - assumes homogeneous USA market and equal sales oftest Inodels • Sales ofmost "Technologically" advanced sets will not meet consumer needs (it won't happen .. model is not "Technologically Advanced")
