TP CHASSIS / TELEVISION
If any problem occurs in the flash integrated circuit, the chassis will not function
because the software in the chassis does not start. As soon as the chassis is
energized, LED located on the front panel will start flashing. This means that main IC
has read and started the software. IF LED is constantly illuminated but not flashing,
and the chassis is not turned on even though it is energized, this means either
software was not read due to a problem in flash IC or it could not be started due to a
problem in main IC.
IC501, IC-SMD STA339BWTR POWERSSO-36 T&R, Audio Amplifier:
The integrated circuit of audio amplifier amplifies digital audio data coming from main
IC to the desired level and sends it out. TP chassis' audio output is 2x10W. IC501
audio amplifier is supplied by 24V VCC_AUDIO voltage. A dedicated circuit is used
to avoid POP NOISE when the TV is turning on and off.
IC500, IC-SMD IC-SMD MAX9728AETC+ T&R, Headphone Amplifier:
There is a dedicated IC500 amplifier for headphone output. After the output has been
filtered on main IC, it is sent to headphone socket through IC500 (MAX9728AETC+).
IC500's supply voltage is 5V.
