Re: telefunken te32883n17

Re: telefunken te32883n17
hello thanks for the nomoresonys answer, I did some tests with the hairdryer and I was unsuccessful. then checked the electrolytic capacitors and replaced some that didn't convince me and checked the power supplies with an oscilloscope. +24v (25v) , 12v(12.7) have a small ripple. i 5v ( 5.17v), 3.3v ok.
with scart socket ok, but as soon as I put a source on hdm1 or hdm2 the tv goes into standby. the command is not given by 17mb62 (stby_on/off) it goes down after switching off. 5.17v present on the power board.
I do not understand the iss...Leave a comment:

telefunken te32883n17
Hi I have a telefunken te32883 TV that goes into standby by itself, with irregular times, then after several standbys the power supply completely shuts down.
Goes to standby on all sources.
power board vestel 17pw25-4 (23012668),
vestel 17mb62-2-6 (110112) motherboard.
I think it's a bios or firmware issue.
it is currently installed as software v.0.0.9a and application version v.0.2.9a
I look forward to info and eventually firmware. thanks bye -
Re: mytv te32

mytv te32
hi all, I have a tv that remains fixed in stand-by, sw mp022-jd power supply would seem ok. i think about a firmware problem, the mather board is a cv306h-f. the eeprom memory 25q32fvsic.
I would need a firmware via usb, or a bios for eeprom. thanks to all greetings zac. -
