Hallo, ik heb een panasonic T.V. type TX-28XD2C. Wie kan mij helpen aan de service code, om het toestel in de test stand te krijgen? Na vervanging van het verticaal ic TDA 8175 is het beeld sterk uitgerekt. Ik denk dit via de service mode te kunnen regelen. Wie kan me helpen?
Uit een andere Panasonic TV service manual (ook een TX28...., maar ik gok dat de manier van servicemenu-benaderen vaak hetzelfde is tussen de diverse modellen):
"The remote control is used for entering and storing adjustments, with the exception of cut-off adjustments which must always be done prior to service adjustment. Perform adjustments in accordance with screen display. The display on the screen also specifies the CCU variants as well as the approximate setting values. The adjustment sequence for the service mode is indicated below.
Set the Bass to maximum position, set the Treble to minimum position Press the Reveal on the remote control and at the same time press the Volume on the customer controls at the front of the TV, this will place the TV into the Service mode Press the RED/GREEN buttons to step down/up through the functions Press the YELLOW/BLUE buttons to alter the function values Press the STORE button on the preset panel after each adjustment has been made to store the required values To exit the Service Mode, press the Normalization button."
