Title: Toshiba 36ZP38B
Post by: markc on June 25, 2010,08:27:46

Hi,
I have one of these that is stuck in standby. I have replaced the module MDFS03, but the fault remains.
The Xtal on the micro is running but there is nothing on the external data/clocks. Not sure if there should be in standby?
Does anyone have any suggestions as to where to go next please.
Thanks
Mark

Thanks for the replies. I had tried removing the text module, but no joy.
I will recheck the CP's. If the micro power on pin is taken low the set will power up, so I don't think it's the scan coils, but its a thought.

An update for those that are interested:
The fault was caused by the remote sensor, although it was sending data to the CPU, the data must have been corrupt or of the wrong level?
