test tda4605
I cant download the file:to few points is the message.
Thanks for the tips.
I would anyway be grateful to know what the starting pulse
at pin 5 of TDA4605 should be without the mosfet connected.
The pulse I messaure with the scope is between 0 volt and 0.25 volt
with a frequensy of...
tranzistor 2sk2545
I shall try to explane more in my bad english.
At the start moment there are a startpulse generator in the TDA4605
to output pin 5.What frequensey and amplitude shall it be.
I have to start the TV without the cmos 2SK2545.
I have two guesses why the mosfet goes S/C at start...
tda4605-3
At the startmoment it shall give pulse out on pin 5 to a CMOS-transistor,
what frequence and amplitude should the pulse have??
It is lokated in the P.S.U of a Beko TV-chassis 11.1,and the
transistor 2SK2545 goes S/C direct with a try to start.

This TV-chassi is a digital 100Hz produced 1998.Does anyone have
the schematic as PDF-file for sale?
The fault:The picture is just around 17",it should be 28",there
are also est/west-fault.The PSU are OK.Grateful for help.
AKAI TV-2561 and TV-2861 has the same chassi.
