    attached is some service info. Service mode about 1/2 way down list.
    IMPORTANT SAFETY NOTICE
    This information is intended for use by individuals possessing adequate background of
    electrical, electronic and mechanical experience. Any attempt to repair a major appliance may
    result in personal injury and property damage. The manufacturer or seller cannot be
    responsible for the interpretation of this information, nor can it assume any liability in connection
    with its use.
    AIR FLOW AND SEALS
    Proper air flow through the dryer is
    essential for normal operation of the
    temperature control and safety systems.
    Air is PULLED into the cabinet from rear.
    A portion of this air is heated by the gas
    burner in the combustion chamber and
    is pulled up the rear duct into the
    diffuser. The remainder of this air
    enters the diffuser directly through
    vents and is mixed with the heated air.
    This hot air is PULLED through the drum
    rear, across the clothes load, through
    the lint trap and down the trap duct into
    the blower. From the blower the air is
    PUSHED out of the exhaust system.
    Any air leaks between the air inlet and
    the blower such as lower drum front felt
    or trap duct to cabinet front sealing will
    result in improper temperatures. The air
    being pulled down the trap duct to the
    drum outlet thermostat will be cooler
    than normal, giving this thermostat a
    false indication (delayed or no-trip).
    Leaks ahead of the blower will also
    reduce the volume of air across the
    combustion chamber causing hot spots
    and possible premature failure.
    TRAP DUCT SEALING
    To inspect the trap duct for proper sealing, remove the lint filter and look
    down into the duct. With a light examine the trap duct on all sides where
    it meets the dryer front for voids in sealing. Leaks may be sealed with
    permagum.
    • WHEN FLEXIBLE DUCT IS USED. WE STRONGLY RECOMMEND METALLIC FLEXIBLE
    DUCT
    • EXHAUST DUCT MUST BE 100 mm (4 INCH) DIAMETER
    • FOR SPECIFIC EXHAUST SPECIFICATION, REFER
    TO INSTALLATION INSTRUCTION SUPPLIED WITH YOUR DRYER
    DRIVE BELT
    The drum is rotated clockwise and counterclockwise,
    as viewed from the front, at a speed of 47-51 RPM.
    Belt tension is maintained by a spring loaded dual idler
    pulley system and driven by a pulley attached to the
    drum motor shaft.
    WHEN SERVICING THE DRYER
    The igniter functioning and the flame can be
    seen through a viewer hole located in the base
    of the dryer. Use a mirror as shown in these
    figures.

    temperature, gas supply (restrictions), gas pressure.
    2. Small loads: Less than 3 lbs. if not treated with destaticizer could develop a static charge if
    over dried and cling to drum surface (no tumble) causing wrinkles, shrinkage, or melting. Use a
    fabric softener (washer or dryer) or add 2 large bath towels to act as a buffer when drying.

How do i eras factory off a phillips tv 2008, model 21PT9457/85?


Your TV has entered into service mode [Factory] mode by somway, due to improper buttons press on remote control. You have to get out from this mode, and to select the normal mode. It will be best to contact any service technician in this case, as this is a semi-skilled work, and should have knowledge to enter service mode and to exit out from it.

Enter service mode


I'm wondering if you realize what little information you have given us to help you with. I have to make major assumptions just to begin... it must be a digital washer to have a service mode... so its a recent model. Generally, service modes are entered by doing things that a consumer would be unlikely to do, like holding several buttons down while turning the unit on. I assume also it has some sort of display to tell you what is going on.
Really, I can't be much help until you give more info - make and model are essential, and perhaps why you want to enter the service mode.
